Abstract

Method and apparatus for a distributed switching system supporting a plurality of services. A service request is initiated by an initiating customer. The service request is then executed using, for example, a user-to-network interface setup. A terminating setup is then performed to either accept or reject the requested service. Multiple service requests are correlated with respective services to enable at least one appropriate policy and logic. Data related to the requested service is obtained using at least one of a push procedure, a pull procedure, a query procedure, and a procedure in which requests are associated with the issuance of certificates

Claims

1. A system for controlling access to a communications network associated with a network service, the system comprising:

a service controller, comprising at least one session initiation protocol (SIP) proxy server, that receives a request for the network service from an initiating end system to access the network service, provides the initiating end system with an enabling certificate, comprising information relating to the permitted setup, and service policy or logic representing service capabilities or service permissions, associated with the network service, and a unique setup identifier, and instructs the initiating end system to perform a connection setup request that includes the certificate and the unique identifier; and

at least one switching device that receives the connection setup request from the initiating end system, the switching device processing the connection setup request based on the certificate and the unique identifier and performing one of establishing a network connection and rejecting the connection setup request based on the processing, in accordance with at least the certificate.

2. The system according to claim 1, the at least one switching device comprising an Internet protocol router.

3. The system according to claim 2, in which the connection setup request is in accordance with resource reservation protocol (RSVP).

4. The system according to claim 1, the at least one switching device comprising a multi-protocol label switching (MPLS) label switching router.

5. The system according to claim 4, in which the connection setup request is in accordance with one of RSVP-te and constraint-based routed label distribution protocol (CR-LDP).

6. The system according to claim 1, the at least one switching device comprising an optical switching device controlled by general multi-protocol label switching (GMPLS).

7. The system according to claim 6, in which the connection setup request is in accordance with one of RSVP-te and constraint-based routed label distribution protocol (CR-LDP).

8. The system according to claim 1, the at least one switching device comprising a time division multiplexing (TDM) switching device controlled by generalized multi-protocol label switching (GMPLS).

9. The system according to claim 8, in which the connection setup request is in accordance with one of RSVP-te and constraint-based routed label distribution protocol (CR-LDP).
