Abstract:With the advent of software-defined networks, network virtualization becomes a key technology to implement softwaredefined networks. Network virtualization requires a path computation element (PCE) to calculate virtual paths to connect virtual network nodes. The Dijkstra's algorithm has been widely used in the PCE to calculate the shortest path between two virtual nodes. In this paper, we address that the Dijkstra's algorithm cannot be applicable when a non-linear cost metric is used in the path cost evaluatio… Show more

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
