1)In this question we consider some of the pros and cons of virtual circuit and
a) Suppose that routers were subject to conditions that might cause them to fail
fairly often. Would this argue in favor of a VC or datagram architecture? Why?
b) Suppose that a source node and a destination require that a fixed amount of
capacity always be a available at all routers on the path between the source and
destination node, for the exclusive use of traffic flowing between this source and
destination node. Would this argue in the favor of VC or datagram networks?
c) Suppose that the links and routers in the network never fail and that routing
paths used between all source/destination pairs remains constant. In this
scenario, does a VC or datagram architecture have more traffic overhead. Why?
