Here is a silly question that I am amazed I dont have an answer for.
If a router has a 1Gbps LAN connection and all the outbound LAN traffic is heading out the router's serial interface, which is only a T1, how does the router handle the disparity in speeds?
In other words, lets say the router is receiving LAN traffic at a rate of 800 Mbps, and all of it is going out the serial interface, which is only 1.5 Mbps, the router will have to buffer a lot of traffic....right? It may drop a lot of it, correct? Lets imagine no QoS applied, just a vanilla set up.
