VPC advantages
Simplified network architecture
- easy separation of network transport functions into those related to a single logical connection (virtual channel) and those related to a group of logical connections (virtual paths).
- Increased network performance and reliability
- reduces the aggregate number of entities that the network has to deal with.
Reduced processing and short connection setup time.
- bulk of control work is done at virtual path setup.
- capacity reservation on VPCs for anticipated future calls allows for VCC establishment with minimal control functions at the end points of VPC.
- transit nodes do not have to do call processing for new calls.
