Abstract
A flow of packet or cell-based communications traffic is monitored by: setting a first time interval over which measurements are to be made; counting number of packets flowing during that time interval and using the count to derive parameters which are indicative of the traffic meeting a sustained cell rate (SCR) requirement. Use of this cell counting method rather than a per-cell computation of a generic cell rate algorithm (GCRA) reduces computation requirements in monitoring traffic. Preferably the cell count is used to derive a running difference between the counted number of packets and an expected number of packets.
