Virtualization Technology for Trustworthy Network Research

Trustworthy network is a new direction of Internet research.This paper analyses current challenge on trustworthy network and points out that virtualization is one of the most efficient way to carry out the research.The authors overview the network virtualization technology and its application in trustworthy network research.Because current network virtualization technology has some shortages for trustworthy network,such as resource management,the authors propose a new virtual network element model—VBN(Virtual Big Node).In this model,multiple network nodes can be aggregated to one VBN,and many virtual mechanisms are applied on it.VBN can decrease network complexity efficiently and enhance survivability and controllability of network transport service as well.
