摘要
针对WTRP网络中令牌只能按节点地址依次传递的现状,论文提出一种新的令牌传递算法,能够根据网络中各节点的报文负荷情况,动态调整令牌在逻辑环上的传递顺序,最大限度地减少令牌在逻辑环上空传的次数。OPNET仿真结果表明,该算法提高了网络吞吐量,降低了报文丢失率,减少了平均服务延时,优于WTRP协议原有的令牌传递算法。
With the actuality of token can only be passed according to the station's address orderly, a new token passing algorithm is proposed. This algorithm adjusts the token passing order on the logic ring dynamically according to the message distribution of stations in the WTRP network, to minimize the times of token passing over the logic ring. OPNET simulation results show that the algorithm has reduced the average service delay, decreased the message drop rate, and increased the network throughput. It is better than the original token passing algorithm of WTRP protocol.
