Preemptive transmission protection scheme for data services

摘要

A method, protection overlay and system in which different service streams are distributed via a plurality of links, comprising logically separating the service streams according to service type profile; allocating resources for working and backup capacity according to the service type profile; and defining a link aggregation group (LAG) including at least one worker link for carrying high priority service streams and at least one backup link for carrying low priority service streams; whereby in response to worker link failure, at least higher priority service streams are transitioned from a failed worker link to a backup link.
