Abstract

Systems and methods for managing interworking protocols are provided. According to one embodiment, a service management system (SMS) communicatively coupled with multiple service processing switches of a service provider provisions transport network interfaces of the service processing switches to provide a transport between subscriber interfaces of the service processing switches. The subscriber interfaces are configured to communicate data in accordance with a first protocol. The transport network interfaces configured to communicate data in accordance with a second protocol. The SMS causes a first-protocol-over-second-protocol (FPoSP) Virtual Private Network (VPN) to be created through which subscriber sites securely exchange data by establishing a virtual router (VR) within the service processing switches corresponding to each subscriber interface. The VRs communicate the data among the service processing switches by encapsulating packets received from the subscriber sites within packets of the second protocol and transmitting the encapsulated packets through the transport network interfaces.
