Abstract: A method includes receiving network information for calculating weighted round-robin (WRR) weights, calculating WRR weights associated with queues based on the network information, and determining whether a highest common factor (HCF) exists in relation to the calculated WRR weights. The method further includes reducing the calculated WRR weights in accordance with the HCF, when it is determined that the HCF exists, and performing a WRR scheduling of packets, stored in the queues, based on the reduced WRR weights.

Abstract: A redundant power supply may obtain a rule for increasing mean time between failures (MTBF) for a first internal power supply and a second internal power supply connected to an electronic device, apply the rule to the first and second power supplies, activate the second internal power supply based on the rule to permit the second internal power supply to provide power to the electronic device, and deactivate the first internal power supply based on the rule.

Abstract: Access switches in a switching system may use virtual aggregated links. When a link between an aggregation switch and an access switch fails, the link failure may be reflected in the virtual aggregated link and data traffic to another access switch may be switched away from the failed switch. A forwarding table in the access switch stores a number of entries that each define a correspondence between destination addresses and an output identifier for the switch. At least a first output identifier includes an aggregated link that represents a first set of possible output links. At least a second output identifier includes a virtual aggregated link, associated with a second network switch that represents a second set of possible output links. Destination addresses in the forwarding table for the virtual aggregated link correspond to network devices connected to the second network switch.
