- Abstract:
- The explicit rate flow control mechanisms for ABR service are used to share the available bandwidth of a bottleneck link fairly and reasonably among many competitive users and to maintain the buffer queue length of a bottleneck switch connected to the link at a desired level in order to avoid and control congestion in ATM networks. However, designing effective flow control mechanisms for the service is known to be difficult because of the variety of dynamic parameters involved such as available link bandwidth, burst of the traffic, the distances between ABR sources and switches. In this paper, we present a fuzzy explicit rate flow control mechanism for ABR service. The mechanism has a simple structure and is robust in the sense that the mechanism’s stability is not sensitive to the change in the number of active virtual connections(VCs). Many simulations show that this mechanism can not only effectively avoid network congestion, but also ensure fair share of the bandwidth for all active VCs regardless of the number of hops they traverse. Additionally, it has the advantages of fast convergence, low oscillation, and high link bandwidth utilization.
- 面向ABR服务的显式速率流量控制机制用于公平和合理地分配瓶颈链路可提供的带宽, 保持与瓶颈链路连接的交换机缓冲区队列长度在所希望的程度, 从而可以预防和控制ATM网络中的拥塞.然而, 设计有效的流量控制机制较为困难, 这主要是由于网络中的动态参数, 如可提供的链路带宽、业务量的并发以及ABR源-目的之间距离等变化的影响.对此, 本文提出了一种面向ABR服务的模糊显式速率控制机制, 该机制结构简单, 鲁棒性强.仿真实验表明:该机制可以有效地避免网络拥塞, 公平地分配链路带宽并且具有快速收敛、低振荡、高链路带宽利用率的特点.
