Method and system for ring topology discovery and forwarding database flush nullification

A node of a communication network ring, the ring including a plurality of nodes, the node comprising:

• a first port and a second port, each first port connected to a second port of a neighboring node through a link, each port operable to receive and transmit data;
• and
• a processor electrically connected to each port, the processor operates to:
• determine a topology of the ring;
• populate static entries in a forwarding database table according to the topology;
• and
• responsive to receiving notice of a failed link, the notice including a source address of a node adjacent to the failed link, the processor further operates to:
• use the topology and the source address of the node adjacent to the failed link to reconfigure the forwarding database table;
• and
• forward data using the reconfigured forwarding database table.

A system for rerouting data in a communication network ring, the system comprising:

• a plurality of nodes interconnected in a ring configuration, each node including:
• a first port and a second port, each port operable to receive and transmit data;
• and
• a processor electrically connected to each port, the processor operating to:
• determine a topology of the ring;
• populate static entries in a forwarding database table according to the topology;
• and
• responsive to receiving notice of a failed link, the notice including a source address of a node adjacent to the failed link, the processor further operating to:
• use the topology and the source address of the node adjacent to the failed link to reconfigure the forwarding database table;
• and
• forward data using the reconfigured forwarding database table.
