Multi-criteria based Optimization of Placement for Software Defined Networking Controllers and Forwarding Nodes

摘要

Placement of Software Defined Networking (SDN) controllers and forwarders in large networks contexts is still a research open issue, given the different network contexts, providers' policies and possible optimization criteria. Multicriteria decision algorithms can provide valuable solutions. This paper is an extension of a previous preliminary work, considering here large network environments and the additional problem of forwarding nodes assignment to SDN controllers.
