Abstract-- In this paper we propose a scheme referred to as dual-
rate session grouping to improve the service rate granularity for cell-based
schedulers. In this scheme a session is split into two subsessions to provide
the average service rate that a user requires. By applying dual-rate ses-
sion grouping, the utilization of bandwidth and fairness among users can
be improved, while the complexity of the scheduling algorithm remains the
same as the conventional scheme. The overall computational complexity of
the dual-rate session grouping does not increase with the rate granularity
that is only limited by the available memory space. Several implementation
issues are also presented in this paper.
