Quality of Service Networking Utilizing Protective Preferential Treatment over a Gigabit Ethernet Environment

A war is being waged within homes, university campus, libraries, government buildings and many other places that appear to be peaceful. The soldiers of this war are highly evolved computer systems, the battlegrounds are aging network environments, and the prize of the war is bandwidth. Computers have grown more powerful from year to year, but networking environments have been hard paced to keep up with the evolutionary changes of CPUs. With the high volume of customers, students, employees and other users that rely on consistent network services; administrators have been plagued with bandwidth woes. Solutions to bandwidth problems are not easy generated or implemented, but by looking at different degrees of network reliability, weakness in current internet protocols, makeup of IP packets and the different transport protocols better understanding of how networks allocate resources can be achieved. Developing quality of service for a particular network environment depends on that individual network, but by implementing preferential treatment to a particular type of network traffic that specified traffic flow could be protected from other programs seeking a higher bandwidth. The research conducted at NASA Ames utilized Gigabit Ethernet connections on two Solaris workstations, a Cisco 7500 router, a Cisco 7206 VXR router, a PCMon system, and a Fast Ethernet connection between another Solaris workstation, the PCMon system, and the two routers. The research conducted was to see weather an isolated flow of data could be protected and guaranteed a specific bandwidth without any regards to other traffic on the network.
