SVC Connections

An SVC is modeled in Cisco 12000/10720 Router Manager as an object deployed beneath two interfaces (see Figure 12-2). The remote endpoint can be a non-Cisco EMF endpoint (that is, outside Cisco EMF)) or a Cisco EMF-endpoint (that is, within Cisco EMF). Deploying and creating an SVC creates a connection between the outgoing port (or source) on one device and the incoming port (or destination) on a second device.

SVCs are similar to PVCs in setup; however, they function differently. The PVC is always operating and is always up. On the other hand, the SVC shuts down when it is not in use. It does not cease to exist, but only goes down until traffic occurs, then it re-establishes again. The SVC saves bandwidth as opposed to the PVC, but is generally slower in operation.
