The VLSI Implementation of A Usage Parameter Control based on Cell Loss Priority

셀손실 우선순위 기반의 사용 변수제어의 VLSI 구현

In this paper, we propose an enhanced usage parameter control algorithm, which is one of the preventive traffic control method in ATM networks and implemented it with VLSI Proposed algorithm is based on the cell loss priority bit in the ATM cell header. This algorithm can solve the measurement phasing problem in cell conformance testing in ATM networks. Proposed algorithm can minimize the cell loss ratio of high priority cell(CLP=0) and resolve the burstiness of cells which may be introduced in traffic multiplexing and demultiplexing procedure. The result of performance evaluation shows that the performance of proposed algorithm is better than that of ITU-T usage parameter control algorithm.
