Abstract:
Abstract. One building block to provide service quality is queueing disciplines such as Random Early Detection (RED). Besides the topic of service dierentiation (e.g., Dierentiated Services), data ows within a service class are expected to receive the same service quality which is expressed in the service quality metric `fairness'. This document evaluates trac phase eects when using RED gateways in conjunction with UDP-based constant bit rate sources. These eects can lead to an unfair division of the available bandwidth among CBR data ows with the same bandwidth share. It is shown that the introduction of randomization may help to improve the fairness.
