Abstract

The performance is compared of first-in-first-out and round-robin packet service disciplines at the trunk nodes of byte-stream networks, including priority service for single-packet messages. Delay and throughput characteristics are surveyed as a function of traffic mix, packet size, traffic intensity, and the ratio of trunk speed to access line speed. Exact and approximate analyses are compared with the results of simulations. Under normal traffic conditions, most disciplines will give acceptable mean delay if the ratio of trunk speed to access line speed is sufficiently high. Under congestion, round-robin disciplines have better fairness properties than first-in-first-out disciplines, in that they protect well-behaved users against hogs.<>
字节流网络中的排队规则和被动拥塞控制
比较了字节流网络中继节点上先进先出和轮循报文服务原则的性能,包括单包消息的优先级服务。时延和吞吐量特性是业务混合、分组大小、业务强度和中继速度与接入线路速度之比的函数。将精确和近似分析结果与仿真结果进行了比较。在正常交通条件下,如果干线速度与接入线路速度的比率足够高,大多数规程都会给出可接受的平均延迟。在拥塞情况下,循环规则比先进先出规则具有更好的公平性,因为它们保护行为良好的用户免受“猪”的侵害。
