CSC Architecture Benefits

The CSC architecture can provide several benefits:

• The CSC backbone carrier can be used by the customer carrier to connect multiple point-to-point POP sites.

• MPLS VPN can be used to separate traffic from different carriers' POP sites.

• A single CSC backbone can provide multiple services, such as MPLS VPN or Internet service, to the customer carrier.

• The MPLS VPN backbone CSC feature removes from the customer carrier the burden of configuring, operating, and maintaining its own backbone.

• The customer carrier can use any addressing scheme because MPLS VPN is used to separate customer carriers.
