Patent ID: 7269131

Claim:
A method for managing a loop network, the loop network including at least two loops, a plurality of devices connected to the at least two loops via ports, wherein at least two of the devices are initiators, the method including: each initiator sending a frame to all other initiators in the loop network identifying any ports which are not to be used; each initiator merging the information from all other initiators with its own information identifying any ports which are not to be used; resulting in all the initiators generating a single set of ports to be used consistent across all the initiators, wherein each initiator applies an algorithm to determine the single set of ports to be used by all the initiators and to balance port accesses across the loop network, wherein the algorithm counts for each loop a number of single port access devices only accessible by a port on that loop and then determines a balance value of accesses across the loops, the method selecting a successive port so as to reduce the balance value towards zero.
