Gulfstream IV Network Proposal

Customer Relations

In less than one hundred years, air travel and networking and computing communications have evolved from the Wright brothers and the UNIVAC housed in several huge rooms to fully functional in-flight Gulfstream network communications. Passengers today expect their palm pilots, laptops and PC's to work as seamlessly as the flight itself. The modern day concerns are mired in the fact that digital conversation now entails a two way link that has inadvertently opened up a can of worms for airline network administrators. Network security and key distribution and management authenticating and authorizing ad-hoc networks have taken on new meaning in the realm of personal aircraft.

The objective here is to tender a viable design regarding the configuration of a fully integrated local area network (LAN) and entertainment system for the Gulfstream IV private business jet. This proposal and design takes in to consideration nothing but the best available equipment that is both cost effective and extremely efficient. There is little doubt that the G4 is a very popular mid-sized business jet which is typically used for mid-range flights lasting up to 6 hours, so passengers will require both entertainment and business functionality. As with most business jets, the passengers require access to Internet connected computers while in flight and the aircraft should permit customers to connect to this network from their own personal Wi-Fi enabled devices. The goal is to allow passengers the flexibly to either use the plane's computers or their own.

Project Proposal


Stage 1 -- Selection of Equipment and Services


8 PC MONITOR -- MIRACLE Business, LD117A 10.4 in Black LCD MonitorMax Resolution: 1024 x 768 / 75 Hz, Image Contrast Ratio: 300:1, Response Time: 40 ms

1 Printer -- Dell Color Laser 3130cn, Print Speed (Actual print speed will vary with use) Up to 31 ppm mono and up to 26 ppm color, Ports10/100BaseT-TX Ethernet, IEEE 1284 Parallel Port, USB 2.0 High speed supported (Type-B connector) Ports Print Speed (Actual print speed will vary with use), Dimensions (W x D. x H) 15.8" x 19.8" x 18.5" Dimensions (W x D. x H)


External communications will utilize the DIRECTV High-Speed Internet bundled packages that utilize the WildBlue Satellite Internet Service for in flight sending and receiving both television and internet connections where DHCP protocol will automatically obtain IP address schemems. This provides access connections for either MAC or Windows-based systems. This service is also extremely fast and reliable, available virtually everywhere in the nation at any altitude and is very affordable. The on-plane CD tower provides a 28 piece CD tower that has 8 drivers per tower outlet which provides almost endless streams of music and movies. The on-board FTP server can receive full/long file structures for file sharing service of all documents, blueprints and oversized data files and will not interfere with bandwidth usage for other outlets.

Propose Network Layout

This proposed network layout is a multicast system where nodes send a packet addressed to the special group address. Devices that are interested in this group register and then receive packets addressed to the group. The Cisco routers send all updates to all of the other Cisco routers throughout the aircraft. The LAN (Local area network) utilizes a short-range star topology that has 8 in seat PC's with internal Network Interface Cards (NIC) and Ethernet cards normally 10 or 100 Mbps as needed, plugged into motherboard. Thus all peripheral nodes are connected via network through individual NIC. There is 1 network color laser printer, 1 multi-read write CD-ROM tower with 28 disk loading capability, 1 dedicated 'large file' FTP receiving server, 2 DirecTV television/Internet in-flight satellite antennas and connection receiving services, all required switch, bridge and routers to connect to internal and external nodes of the network. The backbone of the system entails main cabling based on the Star topology and has a transfer rate of 10 Mbps (megabits per second), while the backbone operates at 100 Mbps. Media Access Control (MAC) address will be maintained via DNS server table for security data capture and are based two equal parts 6 bytes long with the first 3 bytes identify the company that made the NIC and second 3 bytes the serial number of the NIC itself.

Stage 2 Plan the installation

Once the equipment has been selected and the required services planned, the physical installation is as follows.

Floor plan layout

This floor plan is potential assistance layout for the installation of the network. The Network rack holds two routers and 2 servers and all hardware for the AVP cloud Internet connection system to the external DirecTV Satellite receiving antenna on the tail of the plane. The Color Printer and FTP monitor/keyboard will be in the Front left closet. All power outlets, network ports, cable runs, will consist of under the floor wiring schematics from the network closet in the rear of the fuselage to the undersides of each seat for the headrest monitors and food tray keyboards and virtual mice and Bose sound eliminating headsets, and also directly into the front left closet for the printer and the FTP file server monitor. Any necessary wireless link antennas that are needed will be hidden in plain sight via under seat setup or in the roof of the inside of the plane.

Wireless Security -- D5 10 marks

Because Gulfstream is concerned that passenger's files and resources may be vulnerable through the wireless network, network security for the internet and networked environment will have three main objectives. The goals are to meet the basic security needs that entail the mix of internal and external data access, all necessary Internet confidentiality, integrity, and availability needs and to meet the needs of the customer's entertainment needs of television, music and movie interaction systems.

The security objectives of the system entail balancing the information in regard to system authentication, authorization, and nonrepudiation. The system's security software will therefore stop illegal entry into the network and provide levels of data access via a permission table that is regulated and maintained on the DNS server, but will allow for low level access of non-classified data.

IP addressing Scheme

The centrally located DNS server acts in two capacities, to connect to the outside world via a DirecTV Satellite/Internet connection and as the central hub for the internal network utilizing a single static address and allows all other hosts to be configured via DHCP. The DNS server will be a Dell PowerEdge T310 tower server with at least 2Tb of hard disk space, a processor no less than 2 GHz, at least 4Gb of memory, and Gigabit Ethernet. It will have the ability to house all required routing tables and DNS server table connections for both internal and external network communications and also have a separate Dell PowerEdged that act in the capacity of a FTP large file server. The beauty of this type of connection is that the Gulfstream will only require 2 IP addresses for the entire process to work properly, one for the plane to access the internet, the internal cloud technology provides a seemingly virtual connection to the DNS server and parses out the internet bandwidth to each of the internal subnet IP connections. This process will make it seem as though every PC workstation or node has its own direct internet connection similar to a house with a single internet connection and through an antenna provides connections for any PC within range of the signal. A proposed but not final routing scheme is as follows:

DNS Server routing table [IP, seat1 =, seat2 =, seat3 =, seat4 =, seat5 =, seat6=]

Node Router Address table [ Router Table for seat connections, printer1, entertainment system, television,]

FTP 1 Subnet Server [ Router Address,, Router Table, FTP File Server, color printer, Extra]

Packet Tracer Prototype -- D7 20 marks

****** Do not have access to this information or software specs

Use Packet Tracer to prototype the planned network. You don't need to have all 19 computers connected in the simulation, 3 at most…
