FR VPN vs. IP VPN
“Traditional” Frame Relay
- Carrier manages & user pays for multiple PVCs of his virtual network
- Multiple DLCIs required to link each enterprise site to the carrier
- Routed carrier infrastructure - less PVCs to manage and pay for
- Single DLCIs links each enterprise site to the carrier
- No tandem links, flatter network faster, less latency
- End-user traffic is IP/FR
- Carrier terminates FR, routes IP to destination
- Carrier delivers IP/FR back to user
