A system and method for realizing virtualization of traffic generator based on SDN

Abstract

The invention provides a flow generator virtualization realization system and a flow generator virtualization realization method based on SDN, wherein the system and the method belong to the field of communication technology. The system comprises an interaction layer, a control layer and a data layer, wherein the control layer is composed of a topology representing module, a network virtualization module and a flow probe control module. A user performs self definition of a topology experiment according to a self requirement through network topology information which is sensed by the topology representing module. The network virtualization module constructs a flow table with a VLAN identification according to the user-defined topology and self specific characteristics, and transmits the flow table with the VLAN characteristic to an SDN exchange cluster. Network nodes with same VLAN identification form a logical virtual network. A data flows which are generated by the user re transmitted in respectively established virtual logical networks, thereby realizing data isolation of multiple experiment users in parallel operation, satisfying parallel operations of more experiment users, further improving network testing efficiency and reducing fund investment.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to a system and method for realizing virtualization of a traffic generator based on SDN. Background technique [0002] In recent years, business fields such as mobile Internet, cloud computing, and big data have developed rapidly, and the scale of the network has continued to expand. Many problems have emerged in the traditional Internet, such as the high complexity of traditional network configuration. This shows that the network architecture of the traditional Internet needs to be innovated. Software Defined Networking (SDN) was born under this background. SDN is a brand-new network architecture. By separating the control plane of network equipment from the data plane, flexible control of the network is realized, which provides good support for the innovation of the core network and applications. At present, SDN technology has become a hot topic in global network resear...

Problems solved by technology

However, when multiple experimental users need to operate the traffic generating device in parallel, the existing traffic generating system cannot effectively divide the traffic of different experimenters in the same experimental environment due to the different experimental contents.

This makes the experimental process of different users may interfere with each other, and ultimately affect the experimental results of each user
