To enhance greater understanding on the extent the new technology provides benefits for Oak Creek Healthcare; the study reviews the previous work.

1.2: Review of the Previous Work

Vasudh and Jindal (2011) demonstrate the importance of routing for the successful operation and good performances of network. A routing protocol determines the standard and rules the routers communicate with one another, and it selects the exchange of topology information and the best path for the network information flow. Typically, a routing protocol selects the exchange of information to be achieved within the network system without interruption. Within the network information system, delivery of packets is only possible through router. To facilitate the delivery of packets, a router has a routing table that selects exchange of network topological information and the best path router forwards information to different destinations. To enhance the network reliability and availability, a router may make use of (EIGRP) Enhanced Interior Gateway Routing Protocol or IGRP (Interior Gateway Routing Protocol).

However, Fetterolf & Anandalinga (1992) demonstrate that transparent bridges perform much better than router for the interconnection of LANs across WAN. Typically, bridges could provide higher performances devices that could be used to connect LAN at Medium Access Control (MAC) level. The major reason that makes many organizations to consider using bridges is to address the problem of network interconnection for the LAN (Local Area Network) and WAN (Wide Area Network). In the last few decades, there has been an explosive growth in the use LANs (Local Area Network). The LAN provides high-speed data communication for different corporate organizations notable healthcare organizations. However, within large facilities, it is a common procedure to interconnect multiple LANs with transparent bridges. One of the major advantages of bridge is that it monitors LAN automatically in case an unauthorized user attempts to have access to the corporate network. Many corporations are now choosing the bridge technology for the interconnection of LANs for the following reasons:

Bridges have ability to forward packets at much higher rates than routers.

Bridges offer high degree of flexibility and having ability to configure themselves automatically as well as learning IP addresses of the entire host over the internet.

Bridges could better deal with the heterogeneous traffic. Since a bridge operates at Medium Access Control (MAC) level, it could effectively ignore higher level of networks.

Based on the network architecture demonstrated by Fetterolf et al. (1992), the LAN-WAN are interconnected by the transparent bridges. Each bridge has a fixed number of port and within the network system, the two bridges could be used if the number of connections exceed number of ports on the bridges. Thus, within the LAN-WAN connection, WAN has line interface that consists of Tl lines (1.5 Mb), and DDS lines (2.4-56 kb). Despite the benefits of derived from using the bridges for the interconnection of LAN, the routing algorithms of bridges is relatively unsophisticated.

On the other hand, Xu, Papavassilio & Narayana (2004) take different position by pointing out that many organizations have started deploying WLANs (Wireless local area networks) for the network needs. "The IEEE 802.11 speci-cation is becoming the de facto standard for deploying WLANs. However the high data rates achieved by contemporary WLAN technologies are restricted to very short ranges." (P 460). To increase the range of access point of WLAN, the authors propose layer-2 bridging architecture. The bridging architecture aims to address the hotspot communication problem and allow large number of users to have access to network connection. From the performances evaluation, it is believed that layer-2 bridging provides a significant improvement for WLAN compared to a conventional 802.11.

Khalil et al. (1995) demonstrated the methodology that Bellcore organization used to connect WAN topology through LANs. In a contemporary technological environment, LAN plays important role in the network environment and WAN provides distributed network application that connects multiple LANs technologies over large geographical areas. In the last few decades, several organizations make use of different WAN technologies ranging from X.25 of operating rates of 56 Kbits/s to SMDS, BISDN operating to establish scalable network connections. Additionally, many organizations widely use the Ethernet LANs to establish connection on the same geographical area. However, Bellcore organization upgraded the existing LAN and a WAN technology to increase the network bandwidth from 10Mb/s to 100 Mb/s. Bellcore facilitates the modification of the company current network to achieve the following goals:

To support the growing need of network connection within the organization.

To improve the network reliability for the organization

To eliminate the isolation that the company is currently facing.

To enhance reliable protocol using FDDI (Fiber Distributed Data Interface).

Guillen and Chacon (2009) in their own case demonstrate the use of VoIP over the traditional WAN and LAN environment. The use of VoIP is growing in the contemporary business environment and VoIP provides the cost effective and reliable voice communication for many organizations. The growing use of VoIP is due to the quality of service (QoS) that it provides for the enhancement of the organizational efficiency. Despite the benefits derived from the use of VoIP, the authors argue that VoIP is characterized by the delay, packet loss and jitter in its parameters, which affect its quality of service.

The authors further argue that adequate security measure is critical to achieve saved voice communication within an organization. The use of encryption has been identified as an effective strategy to enhance safe communication of data within the network environment. Secured real time protocol (SRTP) is also being identified to enhance the security parameter of WAN and LAN network elements. "SRTP provides protection with encryption keys for wired and wireless networks including bandwidth limited channels." (Guillen and Chacon 2009 P. 690). There is also a growing use of IP secure to protect organization from the interception of data over the LAN and WAN environment.

To enhance network security, Chen, Horng, & Yang (2008) postulate the use of public key cryptography. While there is a growing use of public key cryptography, there is still a shortcoming identified with the use of public key cryptography in the LAN and WAN environment. Since the public key is being kept in a public file, it is possible for an active intruder to forge the contents of the public key and use it to get access onto the data kept within the network system. To overcome the shortcoming identified with the public key cryptography, the private key cryptography is proposed because it has continued to gain recognition in the WAN and LAN security environment.

"The public key is normally used for encrypting messages and is publicly known while the private key is used for decrypting messages and is kept secret. However for generating ? digital signature, the private key is used to sign ? message that can be verified by the corresponding public key" (Murthy & Sudheendra 2008 P. 690).

With the importance of the private key, the security of the private key is important because there could be an unauthorized access to data, if the private key is compromised. The shortcoming of a private key is its large size because it may not be possible for a user to remember the private key each time it is required. Moreover, a sophisticated network attacker could exploit the password-based encryption. To address the shortcoming, the authors propose the use of a biometric security system to enhance the security of cryptographically strong key system. The benefit of a novel biometric-based technique is that a user does not need to "regenerates the private key by using his password, fingerprint and information stored in ? smart card." (Murthy & Sudheendra 2008 P. 690).

Based on the review of the previous work, the study provides the rationale of the project and analysis to arrive at deliverables.

1.3: Project Rationale

The rationale behind the project is to enhance the quality of service delivered by the Oak Creek Healthcare. Based on the project implementation, the company also aims to implement the cost effective and error free healthcare service using the latest technology. The company also aims to achieve better accuracy and higher productivity as well as breaking the distance between patients and physicians using tale-consultancy. Typically, Oak Creek Healthcare attempts to improve its efficiency through the Electronic Health Record (EHR) to store patient information and automated medical records.

More rational behind the project is as follows:

Use of Clinical Decision Support System (CDSS) to provide physician and nurses real time support for diagnosis of patients and treatment.

1.4: Systems Analysis

The major objective that makes Oak Creek Healthcare to implement the new project is that the previous network system could not satisfy the company growth. Hostlinks telecommunication provides system design for Oak Creek Healthcare in accordance with the design methodology, and the Hostlink makes use of Private IP to sustain WAN connectivity for the company. The WAN makes use of provisioned router and a Cisco 7204 to support multimedia as well as maintaining future system development. The Cisco 7204 consists of 4-slot that allows Oak Creek to support multiple protocol as well as connecting LAN across WAN interface.

The WAN design consists of 155 Mbit/s OC-3 circuit being provisioned by the Hostlinks telecommunication to enhance network connection of:

Fairfax Virginia Data Center

Miami Florida Data Center

The Ethernet Gigabit is used to establish LAN connection because of its superior scalability, manageability, its affordability and its ability to provide high quality of service. The WAN and LAN routing protocols consists of Enhanced Interior Gateway Routing Protocol (EIGRP) to allow summarization on interface basis. The EIGRP is also implemented to provide support for the network connection for Oak Creek Healthcare. The LAN architecture of each center consists of Cisco 6509E. For the secured access, the WLAN (Wireless local Area Network) is connected to WLC (Wireless LAN Controller), and there is an implementation of UPS to maintain constant power supply.

IDS (Intrusion Detection System), IPS (Intrusion Prevention System) and firewall are integrated in the network system to enhance the network security. The system also incorporates anti-virus in all the company computers to achieve secured communication and system security. The Cisco router is used for the WAN connection, and the Cisco 7200 is used to connect the 6509E through dual copper Gigabit in order to establish the Ethernet connection. The Gigabit Ethernet of Cisco 7200 is connected to port 5/2 core switch to establish network connection.

B. Project Goals and Objectives

Based on the project development, Oaks Greek Healthcare has attempted to achieve its goals and objectives. However, there are still listed goals and objectives that the organization has not been able to achieve. Some of the listed goals that the Oaks Creek Healthcare has been able to achieve are as follows:

1. Assisting the Oak Creek Healthcare to achieve competitive market advantages with the increase of market shares by 34%:

In the contemporary healthcare sector, the integration of it has proven to be an effective tool to enhance market advantages. While it has been an effective tool to enhance market shares within a healthcare sector, there are still small percentages of healthcare providers embracing network technology to achieve market advantages. Based on the gap identified within the healthcare sector, Oak Creek Healthcare will take the advantages of new technology to increase the market shares by 34%. Through the implementation of new technology, the organization will be able to improve the quality and safety of patients. The report provided by the Medipac (2004) shows that the huge costs of design and implementation of latest network technology has been the major setback that makes many healthcare providers to be unable to integrate the latest network technology to enhance the quality of the service. Thus, the implementation of the latest technology will make Oak Creek Healthcare to enjoy following benefits, which makes the organization to achieve increase in the market shares.

Infrastructure: The company has been able to make use of wireless network to enhance communication. The company has also been able to employ the new technology for the drug transcription using voice recognition system. The new infrastructure has also enhanced the service of physicians as well as overall organization because Oak Creek has been able to employ new inventory control to increase the company market shares.

Administrative Billing and financial: The new technology has been able to improve the billing system within the organization. The waiting time before a patient will see a physician has been greatly reduced since a patient could rapidly pay online, and the system has increased the total number of customers patronizing the organization daily. The new technology has also facilitated patients' registration, and personnel payroll. With the introduction of these new devices, the organization has been able to enjoy increase in the market shares.

Clinical: Within the clinical settings, the computerized order entry for drugs and electronic health record offer improvement on the method the company implements test because the new system has integrated error-alert transcription that is used to reduce and eliminate errors in the clinical settings. With the Clinical Decision Support Systems, the organization has been able to monitor patients electronically. With the implementation of the new system, the company has been able to increase the market shares by 34%.

2. Enhancement of the efficiency of Oak Creek employees

The new project has been able to enhance the efficiency of employee through the creation of electronic health record (EHR). The EHR is the electronic file that integrates text, image, voice and handwritten notes in the electronic file for the creation of patient data. The EHR is also being viewed as a patient tracking system and automated order entry, which enhance the real-time access to data. The new technology enhances the efficiency of employee by several methods:

First, the new technology with the integration of EHR has enhanced the systematic collection of patients' health information thereby reducing the incident of medical errors. Since patient data is now in form of digital format, it would be easy to access patient information in all the clinical setting. Thus, the system has been able to reduce the time taken to access patients' data and the time taken to implement patient care.

Additionally, the new technology enhances the accuracy and clarity of the medical records thereby reduces the incidence of medical errors. The new system also facilitates the method employees carry out their work because the technology has reduced the duplication of tests as well as reducing the delay in carrying out the treatment. Despite the benefits derived from the EHR, there is still a debate on the overall benefits derived from the EHR. There is no doubt that the new system enhances efficiency of employee, however, there is still a debate among the stakeholders whether the new system has actually increased the revenue of the organization to the maximum level because of the inability to carry out the duplicated tests. Before the integration of the new technology, Oak Creek Healthcare had been able to increase the revenue by implementing the duplicated tests. Despite the debate, the organization is still being able to derive overall benefits from the systems.

3. Assisting Oak Creek Healthcare to increase revenue by 45%.

There are several methods by which Oak Creek Healthcare employ to increase the revenue by 45%. First, the electronic billing that the organization has adopted generates additional saving for the organization by decreasing the costs of creating bill thereby speeding reimbursement. Additionally, the decline in the waiting time of patients also enhances the patients' patronage to the organization. Typically, the organization has been able to generate additional revenue from the voice recognition software because the system has been able to lower the transcription costs.

4. Improvement of corporate outlook towards the stakeholders.

The new technology has been able to improve the corporate outlook towards the stakeholders because the company has been able to increase the quality of service as well enhancing the safety of people life. Typically, the new system has offered a significant improvement in the quality of care because patients' information could be accessible to all health providers. One of the major issues that annoy patients within the healthcare sector is to wait for a long time before they receive the Medicare. Since the waiting time has been greatly reduced, the issue has improved the corporate outlook towards the stakeholders. Additionally, the new system has improved the efficiency of employee. With the new technology, employee could now use lesser time to locate the patient data. With traditional filing system, an employee always used longer time to locate employee data, however, with the integration of new technology, the time taken to locate the patient's data has significantly decreased, and the new system has enhanced the efficiency of employees and satisfaction towards their job.

5. Provision of excellent service to patients

The project has enhanced the ability of healthcare providers to provide excellent service to patients because of the decline in the medical error and drug error. In the United States, between 44,000 and 98,000 people die yearly due to the medical errors, and it is one of the critical forces to eliminate medical errors and enhance quality of health and safety. Thus, "linking it to improved quality and patient safety has contributed to a widespread belief that adoption of it in health care will improve quality and safety." (Medpac, 2004 P. 161). Thus, integration of it has enhanced the ability of physicians, clinical technician, and nurses to have ready access to the right information in order to improve the patient's care. Additionally, the new technology has assisted patients to have access to the right information to better manage their conditions as well as communicating with healthcare providers in order to efficiently provide them with high quality of care.

6. Achieving the latest technology for network support

The new system makes use of latest technology such as Cisco 7200 router for the LAN-WAN connectivity. The Cisco 7200 is connected with Gigabit in order to establish the Ethernet connection. The LAN connection also makes use of Cisco 7204 to connect Miami site and Fairfax site, and through WAN technology, Oak Creek Healthcare has been able to connect the two sites together. Additionally, VoIP integrated into the new system has assisted the company to achieve effective communication without interruption. Within the healthcare setting, effective communication is very critical to achieve quality healthcare delivery. Integration of VoIP into the new system has enhanced organizational ability to deliver quality healthcare.

7. Achieving excellent corporate strategy through integration of latest technology

Integration of the latest technology has improved the strategy by which Oak Creek Healthcare manages their business. For example, it is now possible to monitor the performances of employee remotely, and management could now monitor patients online. The new system has also changed the pattern of work because it is now possible for management to implement the e-procurement of medical supply. With e-procurement, it is now possible for management to locate wide number of qualified suppliers, making Oak Creek Healthcare to have power over suppliers.

8. Achieving a state-of-the-art operations at Miami and Fairfax centers

The new technology has made Oak Creek Healthcare to connect Fairfax site and Miami site using WAN technology. While each site possesses the latest technology such as Cisco 7204 to establish LAN, the new technology also makes use of Cisco 7204 for the WAN technology. VoIP technology has also been installed in each site to facilitate easy communication.

9. High-speed network connectivity between Miami and Fairfax.

WAN technology has been integrated to establish high-speed network connection between the two sites. "End site WAN connectivity is sustained over the Hostlink Private IP (PIP) network through the carrier provisioned routers; a Cisco 7204 is provisioned for the primary (OC3) circuit. Each end site is equipped with a Cisco 6509 Multi-layer Catalyst Switch at the core MDF." (Rough Draft, P 3).

10. Achieving a real-time and online videoconferencing that would take place smoothly and transparently

As being discussed previously, the installation of video conferencing is established using Cisco 3845 Voice Gateway to achieve effective communication between the two sites. Typically, communication is very critical to enhance smooth running of organization. Despite the effort of management to integrate the VoIP communication, the VoIP traffic has not yet been configured, and the VoIP Gate way has been configured at minimal level to support management. It is hoped that the design of VoIP will be detailed in the future.

11. Achieving a scalable (LAN) Local Area Networks

The project has implemented a scalable LAN for each site. At Miami and Fairfax site, there is installation of LAN that consists of Cisco 6509E with Core Switch, multiple Cisco 3750E/3560E switches, and MDF (multiple Cisco 3750E/3560E switches) distributed at the end site. The new technology has also facilitated the integration of WLAN (Wireless Local Area Network). A secured WLAN is achieved through WLC (Wireless LAN Controller).

However, the project has difficulties in achieving the following objectives based on the increase in the budget.

Achieving a considerable bandwidth that would support the future networking needs.

Achieving high-level network reliability.

Achieving a flawless LAN to WAN interfaces.

Achieving a secure network with IDS, IPS and firewalls at extranet and internet levels.

Provision of anti-Virus software at the server and desktop levels.

Provision of disaster recovery planning for all serve and network components.

The project manager faces difficulties in achieving the above-named goal and objectives because of the shortage of materials. To overcome the problem, the budget needs to be increased from $1.5 Million to $1.8 Million before the above named goals and objective could be achieved.

C. Project Timeline

Below is the project milestone and based on the stated milestone, the Oak Creek Healthcare ha been able to meet stated timeline for the project:

Preliminary Activities: The project has been able to meet the timeline for the preliminary activity because the company has set aside the budget of $1.5 Million, which is the crucial aspect of the project. Analysis of the whole project reveals that the company will need to $1.5 Million to complete the project. Thus, the management has already engaged for the service of Hostlinks for the implementation of network configuration. Essentially, the Hostlink has large number of it experts who have been assisting Oak Creek in the implementation of the project and this has been achieved within 4 weeks.

Assessment of information security risks is critical to analyze the strategy to protect the new technology against unauthorized intruders. Hotlinks it experts have analyzed the security procedure of the new technology and have identified the necessary security plan that would protect the new technology and this has been done within a week. Moreover, the information security policy has been drawn for the Oak Creek Healthcare to enhance greater understanding of employee about the security procedure they should follow with regard to the new technology. This has also been achieved within a week. Business continuity plan such as disaster recovery plan has also been drawn within 2 weeks. Procurement of hardware & Software such as servers, firewalls, workstations, cable, and anti-virus has also been implemented within 4 weeks. The major factors that make the Oak Creek Healthcare to complete the preliminary activities on time is due to sufficient budget and availability of it experts who are ready to be deployed for the implementation of the project.

Miami LAN upgrading takes 28 days to complete. Within the 28 days, the upgrade of Miami LAN has been achieved due to the following reasons:

First, the Oak Creek Healthcare outsourced the upgrading of the project to an it service provider. Hostlinks Telecommunication is an it service provider that has long years of experience in the upgrading the LAN technology. Typically, the company has capacity to implement the service efficiently and at lower costs. The company decides to offer the upgrading to the external provider because Hostlinks specializes in the implementation of it project. While Oak Greek has a small it department within the hospital, the personnel within the it department could not efficiently carry out the project development.

Moreover, management of Oak Creek Healthcare has drawn a solid contract agreement that stipulates that Hostlinks should deliver the project within the time limit, and if the Hostlinks is unable to deliver the project within the stipulated time, Hostlinks will pay for the inconveniencies caused by the delay in the project delivery. Adding these factors together, the project has been delivered within the stipulated time.

Fairfax LAN Upgrade also takes 20 days to complete. Similar to the Miami LAN upgrading, Hostlinks also completes this project for Oak Creek Healthcare. The solid agreement between the two companies facilitates the completion of the project on time. Typically, outsourcing the non-core business activities is one of the strategies that many organizations implement to achieve competitive advantages. Since the it business is not the core business activities of Oak Creek Healthcare, outsourcing this tasks to the it service providers will make the company to enjoy lower costs in the project implementation and this will make the project to be delivered on time. Based on this believe, upgrading of Fairfax LAN is outsourced to an it service provider, and this has made the project to be delivered within the allotted time frame.

WAN Connectivity to LAN takes 11 days to complete. This project was able to complete within the allotted time frame because all the software and hardware that would be used for the connection are available at Cisco organization. The sufficient budget allotted for the project makes Hostlinks to implement the project with rapidity and on time. The WAN connection to LAN is very critical to enhance communication of the two sites. Availability of necessary hardware such as 7200 WAN router, and 6509E switch and available human and financial resources enhance the completion of the project within the allotted time frame.

Installation and encryption of WLAN (Wireless Local Area Network) take approximately 4 days to complete and this was facilitated using (LWAP) lightweight access points. The installation and encryption is possible thanks to the support provided by the Hostlinks. Moreover, it experts at Oak Creek Healthcare offer support for Hostlinks to ensure that the implementation of the project is completed within the allotted time.

E: PROJECT DEVELOPMENT

The project has accomplished several achievements. First, the project has been able to upgrade LAN technology for the Oak Creek Healthcare. In the contemporary healthcare environment, LAN technology has assisted organizations to share the expensive resources such as printers and PC without necessarily go into the wiring problem. One of the major impacts that LAN has offered to the business performances of Oak Creek company is the easy of transfer of data. The technology has assisted the company to enjoy lower costs with reference to its business activity. Additionally, the project has assisted Oak Creek to easily automate its business operation. With the new technology, the company has been able to use EHR to store patients' data and business information. Using this method, the company has been able to reduce the time taken in accessing the data. The whole process has not only improve the efficiency that the company access data for business operation, the company has also been able to lower cost with the installation of new technology. Since the Ethernet has been used to establish LAN connection for Oak Creek Healthcare, the technology requires the necessary bandwidth requirement that the company will need for the business operation, and this has been installed. Despite the benefits that the project has accomplished with the installation of LAN technology, the project encounters a problem. The troubleshooting encountered is cable testing, protocol analysis, and network management.

The project has also been able to accomplish WAN technology for Oak Creek company. Within the it environment, the LAN network connection is only limited within the limited geographical area. When an organization is attempting to expand into wider geographical area, it is critical to implement WAN technology to enjoy constant network connection across the large geographical area. Since Oak Creek, company has two sites at Miami and Fairfax, WAN technology is the most appropriate technology that will connect the two sites together without having the network interruption. The project has been able to establish WAN technology for the Oak Creek company using the Cisco 7200, and there are several benefits that the company will enjoy from the WAN technology. First, the two sites will enjoy flow of communication and this will allow the company to provide high quality healthcare for patients. Additionally, WAN technology also allows the company to lower the costs of operations and increase the company revenue.

More achievement that the project has also been able to accomplish is the establishing network security to protect the new technology. In the contemporary it environment, new technology is very critical for the business operation, however, there is a need to implement the necessary security procedure to protect the it infrastructure from unauthorized access. This project employs different strategy to protect the new technology from an unauthorized individual. First, the project uses IDS (Intrusion Detection System) and IPS (Intrusion Prevention System). The two technologies are effective to detect and prevent the unauthorized access into the system. More security procedure integrated in the system is the Firewall for the security of the new technology. Firewall is a security procedure that blocks unauthorized traffic that attempts to penetrate into the corporate network. Some unauthorized individual may attempt to sniff the network and steal valuable information if appropriate security procedure is not put in place. To address the problem that might have caused from the security threat, the project installs adequate security protocol onto the new technology. Typically, the firewall technology installed in the project could block, encrypt, permit, or proxy the entire network.
