When is TTL decreased? 1- only at routers? 2- any device having network layer (including hosts in between the path) : example: source subnet has ethernet and destination subnet has token ring : all hosts and routers that come in packets.s path will decrease TTL or only router will decrease TTL?

a) Assume each router implements FIFO queuing. If each flow consists of an identical, 1-Mbps constant bit rate UDP flow with equal packet sizes, what will the resulting rate be for each flow? You can assume that FIFO drops packets with uniform probability. b) Now consider ... and each flow is assigned a weight equal to its number (i.e., flow F4 gets weight 4). What are the resulting throughputs?

If the end hosts in both networks try to send the same set of ... can be successfully transferred simultaneously between the end hosts. The nodes in Network B can be further apart than the nodes in Network A.
