Abstract
Systems and methods for connections on an Automatically Switched Optical Network (ASON) network including an ASON database and path computation algorithm, mechanisms for Ethernet connections over ASON, and mechanisms for label negotiation for SNCs are provided. Advantageously, the present invention provides mechanisms for ASON path computation and virtual topology management, Ethernet connection establishment, modification, and deletion in ASON networks, and label negotiation without requiring binding and releasing of connections before label negotiation.
