Scheduling and admission control support for MPLS service granularity constraint

MPLS services sometimes require that an LSP (label-switched path) be guaranteed a minimal service rate with certain granularity constraint. To support such a service requirement, proper scheduling and admission control mechanisms are needed. We propose two solution that are based on WF/sup 2/Q and DCS, respectively. The corresponding scheduling and admission control policies are designed. The two solutions are compared both analytically and numerically.
