1. Failure: when a node or a trunk fails, it can no longer be used as a part of the rout.2. Congestion: when a particular portion of the network is heavily congested , it is desirable to route packets around rather than through the area of congestion.
In a network switching subsystem, a mobile switching center is the centerpiece. The function of the mobile switching center is to perform the telephony switching functions and serves as a network node.
circuit switching
there are three types of switching techniques 1) circuit switcching 2) Packet switching 3)Message switching
Ethernet
switching complexity
it is very cheap
PSTN
Packet-switching
Switching in data communication refers to the process of directing data packets through a network from a source to a destination. It involves the use of devices, such as switches and routers, to determine the optimal path for data transmission based on factors like network topology and traffic load. There are various switching methods, including circuit switching, packet switching, and message switching, each with distinct advantages and use cases. Effective switching enhances network efficiency and reduces latency in data transfer.
