Abstract:
A method of media access control for packet transmission over a buffer insertion ring, comprising steps performed by each node in the buffer insertion ring of:computing at regular intervals a local packet add rate based on information collected over an interval TSTAT, the regular intervals having a duration T, wherein TSTAT, using the formula: Add_Rate(nT)=(Add_Rate(nTâˆ’T)+DS_Rate(nT))/2 wherein:Add_Rate(nTâˆ’T) is the add rate of the immediately preceding interval T; and DS_Rate is the advertised rate of a downstream link partner node; computing at the same time an advertised packet add rate for an upstream link partner node and communicating the advertised add rate to the upstream link partner node; and adding packets to the ring at a rate that does not exceed the local packet add rate until a new local packet add rate is computed.
