Access link aggregator

摘要

One or more virtual access nodes manage multiple physical links connecting a digital subscriber line access multiplexer and an intelligent network interface device by logically bonding physical ports together into a group. Physical ports bonded in a logical group have equal priority with respect to one another. Thus, no master-slave relationship exists between the physical ports in the logical group. Traffic associated with a site is transmitted over physical links associated with the logical group of physical ports to a customer premises network interface device. The customer premises network interface device subsequently aggregates the received traffic and provides an increased bandwidth to the site over the physical links. The quality of communication is based on the number of operational physical links associated with the logical group. As long as at least one physical link associated with the logical group remains operational, communication will be enabled.
