Implementation of Open Flow-based Virtual Network
GU Xian-fen · Communications technology · 2015
SDN( Software Defined Networking)is a software programmable network framework and technology featuring decoupled data and control planes,and some procotols represented by Open Flow are usd by the control plane to realize central control of the forwarding plane.With these characteristics,SDN framework could fairly meets the demands by cloud-computing for centralized,standardized and automutized configuration and management of virtual network.Aiming at the deficient support for cloud computing platform by traditional virtual network technology,this paper proposes a design of virtual network based on Open Flow-based SDN technology,describes the principles and and processing flows of several virtual network solutions,and finally discusses the modular software design and functions of some key codes.
