Abstract
A network management systems (NMS) queries network elements (NEs) and receives information on cross connects set up at the NEs and other circuit information. Multiple NMS systems can manage the network at the same time. If one NMS changes a cross connect on an NE, the NE will inform the other NMS systems. The cross connect information is used to provide up-to-date information on circuits set up in the network and to facilitate elimination of “orphaned” cross connects which should have been deleted but have not been deleted due to some network failure.
Claims79
A computer readable medium comprising one or more computer instructions to be executed by a network element (NE) operable to implement each of:
- storing, for at least one cross connect configured on the NE, a circuit ID of a circuit that uses the cross connect,
- indicating to a first network management system (NMS) when (i) a cross connect on the NE has been added, deleted, or modified, and (ii) a circuit passing through the NE has been added, deleted or modified, and
- indicating to the first NMS when a cross connect or a circuit on the NE has been added, deleted, or modified on the NE in response to a command issued by a second NMS.
A network system comprising:
- a first and a second network management system (NMS);
- and
- a network element (NE), coupled to the first NMS, comprising circuitry, wherein the circuitry is configured to:
- configure one or more circuits passing through the NE,
- configure one or more cross connects, each cross connect switching an input signal received from a network onto at least one output signal transmitted to the network,
- provide, to the first NMS, information regarding the one or more cross connects and one or more circuits passing through the NE,
- store, for at least one cross connect, a circuit ID of a circuit that uses the cross connect,
- indicate to the first NMS at least one of an addition, a deletion, and a modification of one of a cross connect and circuit on the NE, and
- indicate to the first NMS at least one of an addition, a deletion, and a modification of one of a cross connect and circuit on the NE in response to a command issued by the second NMS.
