Abstract
Abstract: In network function virtualization (NFV), the placement of the virtual network function (VNF) significantly affects the load on switches and the efficiency of bandwidth utilization. Suboptimal placement of VNFs in service chains increases the flow rules in the switches and the ping-pong traffic among the VNFs. This paper presents LightChain, an efficient polynomial run time approach for optimizing VNF placement and service chaining in NFV. LightChain forms the directed acyclic graph of the given service chains and applies ...
