摘要
目前,Internet路由器中拥塞控制机制研究的热点在于:在不破坏网络可扩展性的前提下,如何在路由器上提供拥塞控制机制。该文从信息与激励的角度出发,以部分流状态、核心路由器状态无关、拥塞计费等为3个基本思路,对该领域中已提出的主要研究方案进行了分类阐述和比较分析,总结了其最新研究进展,为下一步的研究提出了新的课题和设想。
This paper summaries the recent research advance in the field providing congestion control mechanisms as powerful and flexible as the ones implemented by a stateful network. In a partial stateful or stateless network, three kinds of mechanisms are introduced for Internet routers: partial per-flow state, stateless core, congestion pricing and their representative implementation schemes are discussed in detail. The paper summaries this research field from the information and incentive point of view, discusses the internal relationships between these mechanisms and analyzes their performance characteristics.
