A logical connection that is made to a virtual circuit.
an endpoint-to-endpoint connection in an ATM network. A virtual connection can be either a virtual path or a virtual channel.
The end-to-end communication path in an ATM network, providing sequential bidirectional transport of ATM cells.
Class of network traffic that defines traffic classification criteria and policies.
A link that seems and behaves like a dedicated point to point line or a system that delivers packets in sequence, as happens on an actual point to point network. In reality, the data is delivered across a network via the most appropriate route. The sending and receiving devices do not have to be aware of the options and the route is chosen only when a message is sent. There is no pre-arrangement, so each virtual connection exists only for the duration of that one transmission.
