Question
Packet-based switches use one of three methods for routing traffic. Describe the THREEmethods. (
Solution
Packet-based switches use one of three methods for routing traffic:
-
Circuit Switching: This is the traditional method of communication in which a dedicated communication path is established between two hosts. The path is exclusively reserved for this connection, and the entire message follows this path. This method is reliable but not very efficient as the path remains idle if no data is being transferred.
-
Packet Switching: In this method, data is broken down into packets and each packet is sent individually. Each packet may take a different path to reach the destination. At the destination, the packets are reassembled to form the original data. This method is more efficient than circuit switching as it allows the network to be shared among multiple users.
-
Message Switching: This is a hybrid of circuit and packet switching. In this method, the entire message is sent to the network at one time, but it is still broken down into packets. However, unlike packet switching, all packets follow the same path. This method is less efficient than packet switching but more efficient than circuit switching.

1.3-2 Packet switching versus circuit switching (1). Which of the characteristics below are associated with the technique of packet switching? Select all correct answers. [Hint: more than one of the answers is correct].Group of answer choicesThis technique is used in the Internet.Resources are used on demand, not reserved in advance.Reserves resources needed for a call from source to destination.Data may be queued before being transmitted due to other user’s data that’s also queueing for transmission.Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) are two approaches for implementing this technique.This technique was the basis for the telephone call switching during the 20th century and into the beginning of this current century.Congestion loss and variable end-end delays are possible with this technique.
