Question

Consider a network including two clients and three network routers. In this example, client C1 is connected to router R1, R1 is connected to router R2, R2 is connected to router R3, and R3 is connected to client C2. Suppose in this example C1 and C2 have 10 simultaneous UDP connections for data transfer. Explain how each of the scenarios listed below influences the data transferred between the clients.

(a) All routers have infinite buffer space, 10Mbps links between clients and routers.

(b) All routers have finite buffer space, 1Gbps links between clients and routers.

(c) All routers have finite buffer space, 10Mbps link between (C1, R1) and (R3, C2), 1Gbps link between (R1, R2) and (R2, R3).

Explanation / Answer

All routers have finite buffer space, 10Mbps link between (C1, R1) and (R3, C2), 1Gbps link between (R1, R2) and (R2, R3).
