Abstract: In one embodiment, primary circuits may be established on a network link, where each primary circuit individually allocates primary bandwidth of the network link and is assigned to one of either a respective primary weighted queue of the network link corresponding to a size of the respective primary circuit or a shared primary weighted queue of the network link corresponding to a total size of the individually allocated primary bandwidth for the network link. In addition, protection circuits may also be established on the network link, where the protection circuits collectively allocate shared backup bandwidth of the network link and are assigned to a shared backup weighted queue of the network link corresponding to a size of the shared backup bandwidth for the network link. As such, primary and backup packets may be forwarded on the network link according to the primary and backup weighted queues (e.g., allowing 1:1 protection).
