Software features
|
- Per-virtual circuit (VC) and per-virtual path (VP) traffic
shaping
- Unspecified bit rate (UBR) traffic shaping
- Fine-grained variable bit rate (VBR) traffic shaping
- Circuit cross-connect (CCC)
- ATM Inverse Address Resolution Protocol (ARP), which enables
routers to automatically learn the IP address of the router on the
far end of an ATM permanent virtual circuit (PVC)
