Abstract

In accordance with one embodiment, a method and system are provided for determining the connectivity of switches in a computer network. The switches include multiple ports for connection to other switches and network elements. Connectivity of the switches is determined by determining all the possible port pairings, determining a score for each port pairing, and selecting the port paring having the highest score.

Claims (7)

1. A method of determining the connectivity of switches in a computer network, each switch including a plurality of ports for connection to other switches and network elements, comprising:

determining all the possible port pairings;

determining a score for each port pairing; and

selecting the port pairing having the highest score.

2. The method of claim 1 wherein the score for each port is determined by determining how well the pairing conforms to a set of given properties.

3. The method of claim 1 wherein said steps are performed by a computer in the network.

4. The method of claim 1 wherein selecting the port pairing having the highest score includes determining a threshold, and discarding scores below the threshold.
