Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048] figure 1 The structure diagram of the measurement system of the present invention is given. It includes a measurement server and n+1 measurement entities obtained by expanding the local log function and clock synchronization function from n switches and a controller. The measurement server performs centralized management on each measurement entity. For the convenience of description, in the OpenFlow network, the switch is called the switch entity, and the controller is called the controller entity; It is abbreviated as measurement entity C1.

[0049] figure 2 The working flow chart of the measurement system of the present invention is given.

[0050] The process starts with initialization step S101, the measurement system expands the local log function and clock synchronization function to the controller entity and n switch entities...

Abstract

The invention discloses a measuring system and method for supporting the analysis of the OpenFlow application performance. The measuring system and method are based on an OpenFlow network and a measuring server. The OpenFlow network comprises a controller and n exchangers connected with the controller respectively. The n exchangers are controlled by the OpenFlow of the controller. The controller and the n exchangers become measuring entities to be controlled by the measuring server in a centralized mode after expanding the local journal function and the clock synchronization function. The measuring system and method for supporting the analysis of the OpenFlow application performance have the advantages that a centralized performance bottleneck does not exist, the interference on the network application by measuring is small, information of a data plane and a control plane can be obtained comprehensively, and an interactive relationship between the control plane and the data plane can be obtained.

Description

technical field [0001] The invention belongs to the field of network communication, and specifically relates to a measurement system and method for supporting quantitative analysis of OpenFlow application performance. Background technique [0002] With the rapid development of technologies such as cloud computing, the Internet of Things, and mobile communications, the fundamental problems faced by the Internet, such as the surge in traffic, support for mobility, multi-homing, and security, cannot be solved under the current Internet framework. It is imperative to redesign and plan the future Internet architecture. OpenFlow-based software-defined networking (Software Defined Networking, SDN) technology provides an innovative platform that can be used to research and deploy new protocols and new algorithms in the network, and provides a new solution to the rigidity problems existing in the existing IP network. The OpenFlow network is mainly composed of two parts: an OpenFlow ...
