Abstract:
A method of scheduling packets for transmission through a Multi-Link Transmission Group (MLTG) of a System Network Architecture network, the method comprising:obtaining link quality information from links in the MLTG;determining delay factors for the links in the MLTG for which link quality information is obtained, the delay factors being calculated by:DELAY=PS/(LS*MLE)+PD+(QL/2)/(LS*MLE)wherein DELAY is an estimate of a delay (in seconds) that a packet experiences over the link, PS is a packet size measured in bits, LS is a link speed for the link, MLE is a measured link efficiency, PD is a propagation delay of the link and QL is an estimate of a current queue level of the link; andscheduling data packets to the links of the MLTG so as to schedule packets to the available link with the lowest delay factor.
