A Method of Bandwidth Allocation Mechanism in ForCES Transport Mapping Layer

This paper proposes a bandwidth allocation mechanism called rate and queue controlled dynamic probabilistic priority (RQ-DPP) based on ForCES transport mapping layer (ForCES TML). We apply this method to counter denial-of-service (DoS) attacks for ForCES router from redirect messages. The algorithm adjusts bandwidths between different messages based on message's kind, per-flow estimated arrival rate and buffer occupancy. By comparing with DRR, the simulation results show the effectiveness of the new bandwidth allocation mechanism.
