Abstract
A system for passive alarm propagation and suppression in a communication network is disclosed. The system includes a packet based network including one subset of network providing connectivity to other set(s) of network. The network includes a first edge node and a second edge node; a first customer node connecting to the first edge node and a second customer node connecting to the second edge node; and a replicated alarm suppression table (RAST) residing in the first provider edge node.
Claims26
A system for passive alarm propagation and suppression in a communication network, comprising:
- a packet-based network, having a first set of domains providing connectivity to a second set of domains, and a plurality of edge nodes;
- a plurality of customer nodes, wherein each of the plurality of customer nodes connects to at least one of the plurality of edge nodes;
- and
- a table correlating a plurality of connections between each of the plurality of customer nodes and at least one of the plurality of edge nodes;
- wherein the plurality of edge nodes comprises:
- a first edge node connecting to a first customer node;
- and
- a second edge node connecting to a second customer node;
- wherein the first edge node checks the table to determine the connection between the first edge node and the second edge node when the first customer node sends a message to the first edge node indicating a connection failure between the first customer node and the second customer node.
A method of passive alarm propagation and suppression in a communication network, comprising the steps of:
- providing a packet-based network, having a first set of domains providing connectivity to a second set of domains, and a plurality of edge nodes;
- providing a plurality of customer nodes, wherein each of the plurality of customer nodes connects to at least one of the plurality of edge nodes;
- and
- providing a table correlating a plurality of connections between each of the plurality of customer nodes and at least one of the plurality of edge nodes;
- wherein the plurality of edge nodes comprises:
- a first edge node connecting to a first customer node;
- and
- a second edge node connecting to a second customer node;
- wherein the first edge node checks the table to determine the connection between the first edge node and the second edge node when the first customer node sends a message to the first edge node indicating a connection failure between the first customer node and the second customer node.
A method of passive alarm propagation and suppression in a communication network, comprising the steps of:
- providing a packet-based provider network, having a first provider edge node and a second provider edge node;
- providing a first customer node connecting to the first provider edge node and a first set of peer customer nodes, and a second customer node connecting to the second provider edge node and a second set of peer customer nodes;
- and
- providing a table correlating a connection between the first provider edge node and the first customer node, and a connection between the second provider edge node and the second customer node;
- wherein the first provider edge node checks the table to determine a connection between the first provider edge node and the second provider edge node when the first customer node sends a message to the first provider edge node, indicating a connection failure between the first customer node and the second customer node.
