Abstract:
Network service providers have largely addressed the growth in demand for communications networks in two ways: employing faster and more robust communications protocols through equipment upgrades and increasing use of Operations, Administrations, and Management (OAM) procedures for improved network performance. Typically, OAM operations procedures used by a network protocol are unique to that protocol and are not compatible with other network protocols. Service providers with networks that use multiple communications protocols, such as networks using legacy and newly installed equipment, can have difficulty ensuring optimal performance due to non-compatible OAM operations. A method, and corresponding apparatus, for supporting OAM interworking between first and second communications protocols used in an interworking circuit of a communications network is disclosed. The method, or corresponding apparatus, allows network service providers to ensure optimal network performance in a manner that does not affect customer traffic, is transparent to customers, and can be seamlessly integrated into existing interworking network nodes.
