组播拥塞控制的研究(英文)

Study On Multicast Congestion Control

组播拥塞控制在避免网络拥塞崩溃和确保在必要带宽单播的公平竞争中是必不可少的。本文在现有的组播拥塞控制方案上提出一类方法。本文的主要贡献是,我们描述了带参数元组{交通法规,分组管理,数据分层和编码,路由器的功能}的组播拥塞控制。同时,优点和缺点也在不同的参数值的选择下被观察,例如基于速率还是基于窗口的,接收器驱动还是发送者驱动。

Multicast congestion control is essential to avoid congestion collapse and ensure fair competition in bandwidth with unicast. This paper presents a classification on existing multicast congestion control schemes. A main contribution in this paper is that we characterize multicast congestion control by a parameters tuple {traffic regulation, group management, data layering and coding, router function}. Meanwhile, the advantages and disadvantages are also investigated in the selection of different parameter values, e.g. whether rate-based or window-based, receiver-driven or sender-driven.
