| 中文摘要 | 现有家庭网络服务质量(QoS)增强方案中一部分采用简单的优先级机制,无法提供参数化QoS特性;另一部分采用集中的轮询调度机制,容易导致单点故障和性能瓶颈问题.针对这一问题,提出了一种用于有线共享信道的多令牌环媒介访问控制机制,设计了复杂令牌调度算法及相应的调度步长分配和准入控制算法,实现了分布式的参数化QoS控制.所提出的复杂令牌调度算法从根本上克服了单令牌环调度能力差和服务区分能力弱的缺陷.仿真结果表明,这一方法可以有效提高网络带宽资源的利用率.; Some of current available quality of service(QoS) enhancement mechanisms for home network are too simple to provide parameterized QoS features,and the others adopt central polling mechanism which may result in single-point fault and performance bottleneck.Aiming at this situation,a new media access control(MAC) mechanism based on multiple token-rings was proposed.The complex token-scheduling algorithm as well as the corresponding resource allocation and admission control algorithms was designed.The distributed parameterized QoS control was realized.The proposed complex token-scheduling algorithm radically overcomes the drawbacks of simple token-scheduling and has stronger resource-scheduling and service-differentiation capabilities.Simulation results showed that the proposed method can effectively improve utilization efficiency of network bandwidth. |
