Abstract
Discrete non-virtualized network elements are characterized by large costs, limited functions, vendor lock-in, and limited orchestration. Network Function Virtualization (NFV) changes the way of creating, deploying, and operating networks by decomposing hardware elements into software components that run on virtualized servers. Two virtualization technologies - Virtual Machines (VM) and containers - have the capability to host Virtual Network Functions (VNFs). These virtualized solutions offer varying results when compared with VNF provisioning time, runtime performance, throughput, and portability depending on the VNF application. Although prior research has identified these results, they lack evaluation of a VNF serving as a Software Defined Network (SDN) controller. In SDN, these parameters serve as a vital criterion for selecting an optimum virtualized solution for hosting an SDN controller, which serves as the control plane for the underlying infrastructure layer. This research paper aims to evaluate an ONOS SDN controller application in a Docker container environment versus a VM environment per the NFV Research Group (NFVRG) testing guidelines. This will help an operator identify an optimum platform to host SDN-VNF microservice.
