Abstract

A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interface directly with the optical communication network.
