A packet-switching network is using a virtual circuit to transmit data from the source to the destination
Question:
A packet-switching network is using a virtual circuit to transmit data from the source to the destination node. In a given instance of data transmission, a message of size 56 octets is to be transmitted from node X to node Y. The virtual circuit designed has 3 intermediate nodes, a, b, and c. Each packet in the network has a 4-octet header that contains the control information. Determine the time of transmission of the message sent from X to Y in each of the following cases:
1. The entire message is sent as a single packet.
2. The message is sent by dividing it into two packets.
3. The message is sent using 7 packets.
4. The message is sent using 14 packets.
5. What conclusion can you draw from the above observation? Assume that the transmission time in each hop is the same.
