  • Method and apparatus for network OAM interworking
    Patent number: 8897145
    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.
