Physical-virtual topological visualization of OF@TEIN SDN-enabled multi-site cloud

Infrastructure visualization based on monitored resource status is essential for the effective operation of modern SDN (Software-Defined Networking)-enabled cloud. More specifically, collecting and visualizing visibility information about both physical & virtual (p+v) types of resources is one of key requirement for multi-site cloud operators. However, most existing visualization tools fall short in effectively providing the p+v topological visualization of multi-site cloud infrastructure. Thus, in this paper, by taking an example of OF@TEIN (OpenFlow @ Trans-Eurasian Information Network) multi-site experimental cloud, we attempt to realize visualization software to assist both developers and operators in capturing the p+v topological visualization of infrastructure resources.
