Network congestion occurs when there is an overwhelming level of packet-based traffic on a network and the Quality of Service (QoS) degrades to the point of users not being able to complete tasks (Wen, Wang, Yang, 2007). The use of Carrier Sense Multiple Access / Collision Avoidance (CSMA/CA) and Carrier Sense Multiple Access/Collision Detection (CSMA/CD) have been designed as protocols to minimize the potential for network congestion to occur. The IBM Token Ring network protocol relies on the CSMA/CA-based approach to mitigate packet collisions and therefore alleviate network congestion. Conversely TCP/IP, which is based on the Ethernet II standard (Chang, Lin, Jin, 2009) relies on the CSMA/CD standard for collision detection of packets on a network. Of these two approaches, the CSMA/CD approach to controlling network congestion is far more prevalent due to the ubiquity of the Internet today. The use of packet analyzers and performance analysis systems and advanced instrumentation give network administrators the opportunity to analyze network traffic over time and understand its causes (Balamash, Krunz, Nain, 2007). Attempts to alleviate or at least reduce network congestion including using Run length Encoding (RLL) for packet size reduction, the use of abbreviated headers for optimizing their path through networks, and the development of protocols that seek to optimize path selection through a network (Wen, Wang, Yang, 2007). The challenge of continually enhancing and increasing network performance through better optimization of paths throughout a network is being made more challenging with the en masse adoption of WiFi as well (Wen, Wang, Yang, 2007).

Congestion in Seaports, Literature Review Overview- Globalization and modern technology over the past 20-30 years has increasingly caused complexity and overcrowding with the world's seaports. In fact, in 2008, the IAPH World Port Conference was so alarmed by trends in the industry that it outlined what it say to be three critical issues and challenges facing global seaports: In the increasingly complicated global environment, it is vital for port executives and experts
In actual fact, because of STCP's option of multiplicative amplify, STCP have to in stable state persuade congestion actions approximately all 13.4 round trip times, in spite of the connection speed. HSTCP encourages packet losses at a slower speed than STCP, but still much quicker than RCP-Reno. 3. Problems of the Existing Delay-based TCP Versions In contrast, TCP Vegas, Enhanced TCP Vegas and FAST TCP are delay-based protocols. By relying upon
Assign to Occupy CONGESTION ISSUES AND SOLUTIONS Prolonged or increased waiting time for patients at the Emergency Department lead to an increase in both morbidity and mortality among critically ill adult patients admitted for inpatient beds. The gathering of ED records of the St. Margaret Mary Healthcare Centers of Dyer, Indiana, aimed at developing a report on overcrowding, identified the main causes as the lack of available inpatient beds and the lack
Networking This report is a follow up to troubleshoot the multimillion-dollar life insurance firm Evco Insurance's corporate headquarters network. "Complex, converged, global networks are the critical underpinnings to today's business processes, communications, and productivity enabling applications." (Networkscouts.com) Initial information provided implies that there are network communication congestion problems and the marketing director stated that at some points of the day there can be 10 minute lags for emails.

Title: Exploring the Basics of Wireless Local Area Networks Introduction In today's digital age, connectivity plays a crucial role in how we communicate and interact with the world around us. One of the technologies that enable this connectivity is Wireless Local Area Networks, commonly known as WLAN or Wi-Fi. A Wireless Local Area Network is a type of network that allows devices to connect and communicate wirelessly within a limited area, such
Disaster Management Communications and Technology in Disaster Management The Importance of Communication and Technology in Disaster Management With the ever increasing chances of disasters occurring in different levels of our societies, the need for institution appropriate disaster management procedures go without saying. The strategic application of processes within organizations and regions, mainly with the aim of protecting the most critical of its assets is a prerequisite (Haddow & Bullock, 2003). With the increasing
