An entry in the switching table of a virtual-circuit network is normally created during the setup phase and deleted during the teardown phase. In other words, the entries in this type of network reflect the current connections, the activity in the network. In contrast, the entries in a routing table of a datagram network do not depend on the current connections; they show the configuration of the network and how any packet should be routed to a final destination. The entries may remain the same even if there is no activity in the network. The routing tables, however, are updated if there are changes in the network. Can you explain the reason for these two different characteristics? Can we say that a virtual-circuit is a connection oriented network and a datagram network is a connectionless network because of the above characteristics?

In what sorts of circumstances would you choose to make use of static route configuration if you were in charge of the management of a network?
A simple network could make use of either static or dynamic routing. The issue that has to be answered is why you would choose one option over the other.
In TCP/IP communication, a session needs to be established before communication and terminated after the communication. With the aid of diagrams critically explain TCP session establishment and termination processes in communication
What does the term "connection status information" mean when applied to a virtual circuit network? A switch's forwarding database must be updated at a rate of one connection per millisecond for the rate at which it generates and removes connections in a VC network (on average).
Draw a sequence diagram for the following scenario. In a network, two nodes communicate with each other. These are the sequence. 1) Node J sends ping message to Node L 2) Node L sends ICMP echo reply to node L. Now Node A is having the MAC address of Node L. 3) Node J starts TCP handshake with Node L by sending SYN message. 4) Node L sends (SYN+ACK) back to node J. 5) Node J sends the ACK to Node L.

A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,500 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?
