Abstract
One embodiment disclosed relates to a method of load balancing traffic in a switching mesh. A packet is received at a switch of the mesh. A MAC destination address is gathered from the packet. An entry in a MAC address table is found with the MAC destination address, and a switch identifier associated with the MAC destination address is obtained. An entry in a switch table is found with the switch identifier, and data associated with the switch identifier is obtained. A hash function is used on field data from the packet to generate a hash value, and the hash value and the associated data are used to generate an index value. An entry in the tag table is found with the index value, and a path tag associated with the index value is obtained. The path tag is inserted into the packet. The path tags may be weighted.
