|Between two end PCs in a WAN or between a user and a server in the internet, there lies a vast list of equipment such as switchers, routers, firewalls, IDSs, etc., all working 24 hours a day, seven days a week and following various disparate technologies such as Ethernet, WLAN, E1/T1, DSL, SDH, FDDI, ATM, etc.; and, all aimed at ensuring that the end systems or users send and receive their required data without any loss, disruption or hassle.|
|Understanding how the entire system works seamlessly in the network is always a thrilling experience for students. The Benchmark NetSys-T – Network Systems Lab – brings this system-level experience to users in a lab environment. Diffusing boundaries between voice and data, wired and wireless, LAN and WAN etc., the Benchmark NetSys-T helps its users to get the feel of a realistic end-to-end network service in a lab environment.|
