A communication channel can be described in terms of four attributes:
- Performance – dictated by the network latency and bandwidth
- Reliability
- Validity - a message put in the outgoing buffer is eventually delivered to the incoming message buffer
- Integrity – the message received is identical to the one sent, and no messages are delivered twice
- Ordering
- A channel is ordered if messages are delivered in the order in which they were sent
- A channel is ordered if messages are delivered in the order in which they were sent
- Synchronicity
- Synchronous – each message transmitted over a channel is received within a known bounded time
- Asynchronous – message transmission time is unbounded
