The three major operational characteristic of an interconnect network are
- Timing
- Switching
- control
Timing control can be synchronous or asynchronous.
Synchronous networks controlled by a global clock that synchronizes all network activities .
Asynchronous network use handshaking or interlocking mechanism to coordinate fast and slow devices.
Network can transfer data using either circuit switching or packet switching.
Network control strategy can be centralized or distributed.
In centralized control, a global controller receives requests from all the device attached to the network and grants the network one or more requests.
In distributed system, requests are handled by local devices independently.
