Datagram subnets route each packet as a separate unit, independent of all others. Virtual-circuit subnets do not have to do this, since each data packet follows a predetermined route. Does this observation mean that virtual-circuit subnets do not need the capability to route isolated packets from an arbitrary source to an arbitrary destination? Explain your answer.
Answer to relevant QuestionsGive three examples of protocol parameters that might be negotiated when a connection is set up.Consider the subnet of Fig. 5-13(a). Distance vector routing is used, and the following vectors have just come in to router C: from B: (5, 0, 8, 12, 6, 2); from D: (16, 12, 6, 0, 9, 10); and from E: (7, 6, 3, 9, 0, 4), the ...Compute a multicast spanning tree for router C in the following subnet for a group with members at routers A, B, C, D, E, F, I, and K.Give an argument why the leaky bucket algorithm should allow just one packet per tick, independent of how large the packet is.Tunneling through a concatenated virtual-circuit subnet is straightforward: the multi protocol router at one end just sets up a virtual circuit to the other end and passes packets through it. Can tunneling also be used in ...
