MultiPoint Link Aggregation
A point-to-point-only technology that extends link aggregation to offer dual-homed resiliency similar to that provided by FDDI, but with the added benefit of load sharing. MPLA protects against both link failure and equipment failure and allows for full use of resources since all physical links are active. MPLA dramatically increases the capacity of connections and availability for high-speed Ethernet-based campus LANs.
