Abstract:
Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions. The systems and methods prioritize packets and make discard decisions based upon the prioritization. Some embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, other embodiments provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, others provide a proactive response by discarding packets based on predicted oversubscription, and others provide a combination thereof.

Claim (Index 20):
A non-transitory storage medium which records a plurality of computer executable instructions loaded into a processor of a network device to execute functions comprising:\n determining that one or more of the communication services is a video service having packets carrying video frames; determining, for each of the one or more determined video services, a plurality of video frame discard levels each of which has an associated frame discard criteria and a maximum degradation threshold; and scheduling transmissions to one or more of the plurality of subscriber stations by:\n determining whether an anticipated bandwidth consumption for supporting all of a plurality of currently operating communication services in their current operating states is greater than a total available bandwidth of the network device, \n selecting, in the case that the anticipated bandwidth consumption for supporting all currently operating communication services in their current operating states is greater than the total available bandwidth of the network device, one of the plurality of video frame discard levels for each of the one or more determined video services by calculating, for each of the one or more determined video services, an estimated quality degradation level to be below the maximum quality degradation threshold by applying the one of the plurality of video frame discard levels as long as the adjusted bandwidth consumption for supporting all currently operating communication services is reduced to fit within the total available bandwidth of the network device, \n selecting, for each determined video service, all packets carrying video frames that meet the discard criteria associated with the selected video frame discard level for the determined video service, and \n discarding the selected packets prior to a time for their transmission to one or more of the plurality of subscriber stations.
