ATM and Frame Relay SVCs and SPVCs

With a co-located Extended Services Processor (ESP), the BPX switch adds the capability to support ATM and Frame Relay switched virtual circuits (SVCs) in addition to support for permanent virtual circuits (PVCs) as shown in Figure 8-1.

The Private Network to Network Interface (PNNI) protocol is used to route SVCs across the network. PNNI provides a dynamic routing protocol which is responsive to changes in network availability and will scale to large networks.

BPX switch resources, such as port VPI range and trunk bandwidth are partitioned between SVCs and PVCs. This provides a firewall between the two types of connections so that any SVCs that come on-line and off-line do not affect the availability of existing PVC services.

The following connections are supported with Release 9.1:

•Frame Relay SVC connections between Frame Relay end users over an ATM network (Network Interworking)

•

•

ATM SVC connections between ATM end users
