AN EFFICIENT POLICER BASED WEIGHTED FAIR BANDWIDTH DISTRIBUTION SYSTEM

摘要

An efficient policer based weighted fairness bandwidth distribution system is disclosed. The system is based on a plurality of policcrs and a single queue. To achieve fairness, the rate for queuing packets is adaptively controlled. Specifically, first the queue occupancy is determined and it then is used for computing an attenuation (Attn) value. This value is multiplied by the excess information rate (EIR) of each policer to get a new EIR to be enforced.
