In recent years, there is a growing interest in using SDN, which uses virtual networks, rather than developing physical technologies of networks. In other words, the virtual network utilizes existing physical resources to construct a software network. In this case, the minimum physical network resources must be supported in order to be used for the purpose. When using the resources provided by the PIP, if there is no physical connection or if the capacity is insufficient, it may not provide the desired performance. In this paper, we assume that survivability of a virtual network are implemented using only existing PIPs and that additional resources utilization of physical connection (link addition) is utilized The efficiency of each of them was compared and analyzed. The efficiency here is about the coverage and cost of survivability. That is, it analyzes the survivability of the virtual network according to the physical structure of the network. When the number of virtual networks is small, survivability is greatly influenced by the physical network structure. However, as the number of virtual networks increases, it is confirmed that survivability is not significantly influenced by the physical network structure. |
