In this question, we consider some of the pros and cons of virtual-circuit and datagram networks.
a. Suppose that routers were subjected to conditions that might cause them to fail fairly often. Would this argue in favor of VC or datagram architecture? Why?
b. Suppose that a source node and a destination require that a fixed amount of capacity always be 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 favor of a VC or datagram architecture? Why?
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 control traffic overhead? Why?
Suppose there is a Certificate Authority (CA) with well-known public key. Further suppose every user is issued a certificate for his/her public key.
