Smart control plane for information centric network-internet service provider networks

The information centric network(ICN)has been widely discussed in current researches.The ICN interoperation with a traditional IP network and caching methods are one of the research topics of interest.For economic reasons,the capability of applying the ICN to internet service providers(ISPs)with various traditional IP protocols already implemented,especially IGP,MPLS,VRF,and TE,does not require any change on the IP network infrastructure.The biggest concern of ISPs is related to their customers’contents delivery speed.In this paper,we consider ICN caching locations in ISP by using the concept of locator/ID separation protocol(LISP)for interoperation between a traditional IP address and name-based ICN.To be more specific,we propose a new procedure to determine caching locations in the ICN by using the cuckoo search algorithm(CSA)for finding the best caching locations of information chunks.Moreover,we create the smart control plane(SCP)scheme which is an intelligent controlling,managing,and mapping system.Its function is similar to the software defined network concept.We show how the proposed SCP system works in both synthetic small network and real-world big network.Finally,we show and evaluate the performance of our algorithm comparison with the simple search method using the shortest path first algorithm.

基于OTN技术下智能光网络相关技术研究

近些年来网络通讯技术不断的更新升级,其发展前景也越来越广。但在通信技术发展的过程中也会遇到一些问题,例如当前的相关技术发展的还不太完善,通讯速度以及信号质量还有待提高等,对于这些问题经过研究人员不断的努力,最终研发出了OTN技术,该技术也逐渐成为传输网组网技术中的一部分。OTN技术主要是为了实现全光组网,在通信网络内部进行合理地调整。本文主要在我国通信智能光网络技术发展现状的基础上,进一步对OTN技术在智能网络中的应用进行研究,主要从该技术的检测、智能控制平面技术、OTN交叉技术的角度出发进行深入研究,不断促进我国网络通信技术的发展。
