摘要:

内容中心网络(content-centric networking,CCN)作为一种全新的网络体系结构,对路由算法的设计提出了许多新的挑战。针对CCN的特点,提出了一种基于温度场的路由(temperature field based routing,TFBR)算法,将物理学中稳态温度场的概念引入CCN,并采用有限元法求解稳态温度场,形成路由转发决策。仿真实验表明,TFBR 算法能够充分利用CCN 的路由节点缓存功能,在降低网络平均时延性能的同时,提高了CCN 的负载均衡性能。

Abstract:

Content-centric networking(CCN)is a novel network architecture which presents new challenges for the design of routing. Aiming at the characteristics of CCN, a temperature field based routing(TFBR)algorithm was proposed. This scheme introduced the conception of temperature fields in physics into CCN and applied a finite element method(FEM), which is one of numerical analysis techniques, to assign a temperature value to each node of CCN in a distributed way. Simulation results show that TFBR can adequately utilize the cache in CCN nodes and decrease the network average delay while improving the performance of load balancing.

Key words: content-centric networking, routing, cache, temperature field
