Computer Networking: Worst Case Scenario

[sleepycorey]

Homework Statement

Router architecture. Consider a router with a T1 serial interface and two 100 Mbps Ethernet interfaces. The router has a 1 GB buffer for storing packet traffic. Calculate, in the worst case, how long the router can sustain loss-less operations. Define carefully what traffic pattern will result in the worst case scenario.

The Attempt at a Solution

It has been a while since I've done anything with networking. I am pretty sure this is not as simple as if the two interfaces are both inputting 100 Mbps, the queue would get filled in 5 msec. I know the cpu will process some of the packets, but I do not quite remember everything

If you think you can download 1GB of data in 5 msec over 2 100Mbps lines you are going to be disappointed next time you download a movie...

100Mbps is how many MBps? And how many MB in a GB?
