Adaptive load balancing (ALB) for Aggregated Ethernet

Adaptive load balancing (ALB) uses a feedback mechanism to correct a genuine traffic imbalance. To correct the imbalance weights, the bandwidth and packet stream of links are adapted to achieve efficient traffic distribution across the links in an aggregated Ethernet bundle. Network administrators use this feature to manage uneven or overloaded data flows on member links. The algorithm determines which link to use by considering the scanned packet or bit rate associated with each hash value in conjunction with the mapping of hash values to a given link. ALB is applied to IPv4, IPv6, and MPLS packet headers. ALB is disabled by default.
