Comparison of Datagram and Virtual Circuit Subnet
Issue Datagram Virtual CircuitConnection SetupNoneRequiredAddressingPacket contains full source and destination addressPacket contains short virtual circuit number identifier.State informationNone other than router table containing destination networkEach virtual circuit number entered to table on setup, used for routing.RoutingPackets routed independentlyRoute established at setup, all packets follow same route.Effect of router failureOnly on packets lost during crashAll virtual circuits passing through failed router terminated.Congestion controlDifficult since all packets routed independently router resource requirements can vary.Simple by pre-allocating enough

What is the Difference between datagram network and virtual circuit network?
Not a whole answer but a small try :)In a Datagram Network, there's no "network-layer-connection" between the two hosts. So Theres no garuanteed bandwith and the packets may take different paths.In a Virutal Circuit network, its oppositly and a connection is established.------------------------------------------------------------------------------------------------------------ •There are a number of important differences between virtual circuit and datagram networks. •The choice strongly impacts complexity of the different types of node.•Use of datagrams between intermediate nodes allows relatively simple protocols at this level,-but at the expense of making the end (user) nodes more complex when end-to-end virtual circuit service is desired.•The Internet transmits datagrams between intermediate nodes using IP. •Most Internet users need additional functions such as end-to-end error and sequence control to give a reliable service (equivalent to that provided by virtual circuits).•This reliablility may be provided by-the Transmission Control Protocol (TCP) which is used end-to-end across the Internet,-or by applications such as the trivial file transfer protocol (tftp) running on top of the User Datagram Protocol (UDP).
Differentiate SVC'S and PVC's?
Difference between a PVC-Permanent Virtual Circuit and SVC-Switched Virtual Circuit is that an SVC must be reestablished each time data is to be sent. After that SVC disappears.
