Pros and Cons of Message Switching

Message Switching

ADVANTAGES
1. It provides efficient traffic management by assigning priorities to the messages to be switched.
2. No physical connection is required between the source & destination as it is in circuit switching.
3. It reduces the traffic congestion on network because of store & forward facility. Each node can store the message until communication channel becomes available.
4. Channels are used effectively and network devices share the data channels.
5. It supports the message length of unlimited size.

DISADVANTAGES of Message Switching
1. As message length is unlimited, each switching node must have sufficient storage to buffer message.
2. Storing & forwarding facility introduces delay thus making message switching unsuitable for real time applications like voice and video.
