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.
Figure 12-2 SVC Connection
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.
