有线网络中虚拟网络映射算法研究
Research on virtual network embedding in wired network
摘要
Abstract
Network virtualization is recognized as a key technology for the future Internet.It helps to overcome the ossification problem on the current network and can evaluate new protocols and services without the need to make fundamental changes on current network architecture.As a result,multiple virtual networks (VNs) share the same physical network and new problem occurs which is how to allocate limited physical resources to multiple VNs in a reasonable and effective way,namely virtual network embedding(VNE) problem.According to the network environment,VNE includes embedding in wired network and in wireless network.VNE in wired network is the foundation and the key of VNE problem.A lot of algorithms have been proposed.To provide a comprehensive view of the problem,this paper presented a survey of current VNE algorithms in wired network from the aspects of the definition of the problem,the challenges and embedding objects.It proposed the classification of VNE algorithms according to their characteristics and compared several typical VNE algorithms.At last,it discussed the future research trends.关键词
