摘要
域间路由中每个自治系统都是独立的理性主体,它们策略性地选择行为,进行路由.倘若自治系统的路由策略不加限制则会引起网络运行异常.借助于专门研究理性主体自利行为的机制设计理论,激励自治系统,可以在保证每个自治系统利益的前提下,实现域间路由网络系统的整体目标.首先概述了机制设计理论,接着将目前域间路由中的机制设计研究归纳为最小代价路由机制设计和策略路由机制设计,总结了研究现状.最后指出未来研究方向.
Every autonomous system in interdomain routing is an independent rational agent. They choose actions strategically to route. If all agents are allowed to act arbitrarily, the network will work abnormally. Based on mechanism design theory in microeconomics, the whole network's target can be realized through incentive. At the same time, the interests of autonomous systems are also satisfied. Firstly, mechanism design theory is introduced briefly. Mechanism design models in interdomain routing are classified into two models: lowest-cost-path mechanism design and policy based routing mechanism design. These two models" research advances are summarized. Finally, future research directions are proposed.
