Link capacity sharing for throughput-blocking optimally in a mixed rigid-elastic traffic environment by dividing the bandwidth into common and dedicated parts

摘要

Link capacity sharing and packet scheduling normally reside in the Internet protocol router (20) and cutoff parameters are forwarded to a call admission control unit (22) from a control unit (21), which accepts or rejects new flows based on the parameters. For each requested new flow, the traffic class is determined so that admission control can be performed and accepted packets are forwarded to an output port buffer (23) for scheduling to the output port scheduler (25), where the output link is bandwidth allocated into common and dedicated parts, the latter for elastic traffic only. Independent claims are included for a link capacity sharing device and for a method for determining a steady distribution of a Markov chain of dynamics in a network link.
