Carrier Supporting Carrier: With Customer Carrier Providing MPLS VPN Services to User Sites

To connect geographically separated customer sites and to implement VPNs, most service providers are adopting MPLS technology. MPLSVPN is a service provides quality of service and secured private connection to exchange the information between two customer's sites connected to the ISP situated in distinct geographical areas. If the ISP doesn't have interconnectivity of their own areas where the customer sites are available, the provision of MPLSVPNs can be done by using the transport services of another ISP i.e. Carrier Supporting Carrier. In this project, we threw some light on a new method of providing MPLSVPN service between the branches of a customer connected to one ISP using Carrier Supporting Carrier methodology. The Carrier, who is supporting the other Carrier in the interconnection of their areas will treat this connection as an MPLSVPN at both ends and delivers traffic from one area to other area. Carrier can use that link to send internet / VPN Traffic as per their requirement.
