摘要
针对ATM网络中不同业务的需要 ,提出了一种采用FIFO机制的易于实现的单队列缓存分配方案 ,但该方案为了获得较高的链路利用率就需要较大的缓存空间·因此进一步提出了旨在减少信息对缓存的占用的多队列链路速率分配算法 ,并求解了链路速率的分配规则表达式·理论分析表明 ,该算法能够在一定程度上克服单队列缓存分配算法对缓存空间的耗费 ,并保证链路速率的合理分配·
A single buffer allocation scheme based on FIFO, was proposed according different service needed in ATM networks. Although the schemewhich may be easy to implement,it would cost very large buffer in order to achieve flow rate guarantee and high link utility. Then in order to decrease the buffer share, a multi buffer link rate allocation algorithm was provided, and its exact expression onto a link rate allocation rule was investigated also. The multi buffer link rate algorithm can decrease the disadvantage of the single buffer allocation scheme,at the same time it remain the reasonable link rate allocation.
