网络拥塞在分组无线网(PRNET)中是一个潜在的问题,为减轻或避免拥塞的摧毁效应,在PRNET中,有必要对拥塞进行控制。本文首先分析了以往的拥塞控制中存在的问题,然后介绍了两种新的相互合作的拥塞控制技术——建立长期最大—最小端到端流率的端到端拥塞控制算法以及链路层拥塞避免算法,最后对这两种机制的性能进行了相应的分析与评价。 Network congestion is a potential problem in the packet radio network (PRNET). To reduce or eliminate the destructive effects of congestion, it is necessary to control congestion in PRNET. This paper first analyzes the existing problems in congestion control and then introduces two new collaborative congestion control techniques: establishing long-term maximum-minimum end-to-end flow rate end-to-end congestion control algorithm and link layer congestion Avoid the algorithm, and finally analyze and evaluate the performance of these two mechanisms.
