GFR 서비스를 위한 퍼지기반 버퍼관리 기법
Fuzzy Based Buffer Management Scheme for ATM-GFR Service
초록
To support Internet traffic efficiently over ATM \networks, Guaranteed Frame Rate(GFR) has been proposed in tile ATM Forum to ensure minimum rate guarantees to VCs. In this paper, we proposed fuzzy logic based buffer management algorithm that provides MCR guarantee and fair sharing to GFR VCs. A key feature of proposed algorithm is its ability to accept or drop a new incoming packet dynamically based on buffer condition and load rate of VCs. This is achieved by using fuzzy logic controller for the production of a drop factor. Simulation result shows that proposed scheme significantly has improved fairness and TCP throughput compared with previous schemes.
