HASH-BASED MULTI-HOMING

摘要

A method for communication between first and second nodes (24, 28) via a communication network (32) including assigning multiple communication ports (40A, 40B, 40C) between the first and second nodes to serve as member ports of a multi-homing group (MHG) (44) as shown in Figure 1. Each of the member ports is associated with a different, respective communication path between the first and second nodes via the communication network. A frame transmitted for the first node to the second node is accepted at the two or more network nodes. The frame has a header including header fields. A single port is selected form among the member ports by applying a hashing function to one or more of the header fields at each of the two or more network nodes. The frame is forwarded via the selected port over the respective communication path that is associated with the selected port.
