Abstract
A node in a mobile ad-hoc network or other network classifies packets (a) in accordance with a first set of priority levels based on urgency and (b) within each priority level of the first set, in accordance with a second set of priority levels based on importance. The node: (a) queues packets classified at highest priority levels of the first and/or second sets in high-priority output queues; (b) queues packets classified at medium priority levels of the first set in medium-priority output queue(s); and (3) queues packets classified at low priority levels of the first and/or second set in low-priority output queue(s). Using an output priority scheduler, the node serves the packets in order of the priorities of the output queues. In such manner, orthogonal aspects of DiffServ and MLPP can be resolved in a MANET or other network.
