Permanent Virtual Connections
A PVC is a permanent connection established by a network administrator between two end-points
pertaining to the network, as opposed to an SVC, which is a connection established dynamically on an
end-user station request, and between two end-user devices.
A PVC is established between 2 (more if multicast) end-points pertaining to the network, with specific
traffic characteristics (best effort, reserved bandwidth...).
There are two types of PVC:
Point-to-point, which has one source end-point and one target end point
Point-to-multipoint, which has one source end-point, and several target end-points. Each additional
end-point is called a party or a branch of the multicast tree. The traffic characteristics are common for
all the parties of a PVC.
The two end-points of a PVC may be on the same 8265, or on different 8265s. In the latter case, the path
may be selected either by the routing protocol (PNNI, for example) or by creating several PVCs in each
8265 until the final end point is reached.
PVCs are created, and deleted, via the terminal dialog. Between these 2 events, the PVC is active, unless
a network failure occurs. If this happens, up to 20 attempts (with 15 second intervals) are made to
re-establish the connection.
PVC's are automatically established when an 8265 is reset or powered on.
A PVC is automatically saved after it has been activated successfully.
The 8265 supports a maximum of 512 PVCs.
