Method and apparatus for determining communication path over network by using spanning tree and circuit detection
First Claim
1. A method of determining a communication path over a network, the method comprising:
- (a) generating a spanning tree having connection devices over a network as vertices and having links among the connection devices as edges;
(b) allotting predetermined vertex information to each vertex on the spanning tree;
(c) detecting all circuits having a plurality of communication paths among the connection devices over the network corresponding to the spanning tree; and
(d) applying rapid ring spanning tree protocol (RRSTP) to links corresponding to the detected circuits and applying rapid spanning tree protocol (RSTP) to links not corresponding to the detected circuits.
