长路径链路调度的统计分析

Statistical Analysis of Link Scheduling on Long Paths

Yashar Ghiassi-Farrokhfal, Jorg Liebeherr, Almut Burchard

摘要:

我们研究如何选择的数据包调度算法的影响端到端的性能长的网络路径。以网络演算的方法,我们认为确定性和统计性能指标。我们的分析的一个关键的贡献是一个显着锐化的方法计算的统计界限的服务流作为一个整体的网络。对于一个适当的吝啬的交通模型,我们开发了封闭形式的表达式的端到端的延迟,积压,输出突发。我们的边界的确定性版本产生端到端的积压和输出突发的最佳界限,为一些路由器,并高度准确的端到端的延迟界限。

英文摘要:

We study how the choice of packet scheduling algorithms influences end-to-end performance on long network paths. Taking a network calculus approach, we consider both deterministic and statistical performance metrics. A key enabling contribution for our analysis is a significantly sharpened method for computing a statistical bound for the service given to a flow by the network as a whole. For a suitably parsimonious traffic model we develop closed-form expressions for end-to-end delays, backlog, and output burstiness. The deterministic versions of our bounds yield optimal bounds on end-to-end backlog and output burstiness for some schedulers, and are highly accurate for end-to-end delay bounds.
