FLOW DISTRIBUTION ALGORITHM FOR AGGREGATED LINKS IN AN ETHERNET SWITCH

摘要

Link aggregation is a practice that uses multiple Ethernet links between two end points in order to obtain higher bandwidth and resiliency than possible with a single link. A flow distribution technique is provided to distribute traffic between the two end points equally across all links in the group and achieve greater efficiency. The flow distribution technique generates and sub-divides a hash value based on received packet flow. The divided portions of the hash value are used in a hierarchical fashion to select a link to use for this packet.
