Patent number: 10523458Abstract: A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations.Type: GrantFiled: February 12, 2019Date of Patent: December 31, 2019Assignee: Extreme Networks, Inc.Inventors: Liwu Liu, Jianlin Zeng
