Topology discovery and identification of switches in a three-stage interconnection network

摘要

Topology discovery and identification of switches enables a user to determine the topology of a three-stage switch network. The method includes ascertaining an intended topology of the three-stage switch network, creating a list of switch boards that are present in the three-stage switch network, and determining a switch board connection pattern by obtaining information indicating how each switch board is connected to neighboring switch boards. The method further includes classifying each of the switch boards on the list of switch boards as a node switch board, an intermediate switch board, or a jump switch board, and creating a list for each type of switch board. The method further includes grouping the intermediate and node switch boards into sectors, and numbering each type of switch board, thereby obtaining a determined topology, and validating the determined topology by comparing it to the intended topology.
