Virtual Network Mapping Model and Embedding Algorithms
Zou Xiaohu · Intelligent Computer and Applications · 2014
Virtual network mapping is one of the key problems of network virtualization,the target of which is to allocate appropriate physical nodes and links of substrate network to virtual network requests,and construct multiple heterogeneous virtual networks isolated from each other on the shared physical network infrastructures,in order to provide an experimental platform for innovative research of network infrastructures and carry new network applications. The paper formulates the virtual network mapping models,overviews the virtual network embedding algorithms,and proposes that the minimal cut set theory can be employed for embedding virtual networks to substrate network infrastructures.
