A netflow-based sdn network traffic statistics device and method

Abstract

The invention discloses a Netflow-based SDN network flow statistics device and method, the device includes an SDN controller, a first Netflow collector, a Netflow transit network, and an Influxdb database, and the first Netflow collector collects and sends Netflow flow data of network equipment To the Netflow transit network, the Netflow transit network aggregates and filters the Netflow flow data collected and stores it in the Netflow buffer of the second Netflow collector; Stored in the Influxdb database. The invention not only can count the network traffic without additional traffic monitoring equipment and traffic analysis equipment, but also simplifies the SDN network networking scheme.

Description

technical field [0001] The invention relates to a Netflow-based SDN network traffic statistics device and method, belonging to the technical field of communications. Background technique [0002] SDN (Software Defined Network, software defined network) network is a new type of network architecture, which has three basic characteristics of separation of transfer and control, centralized control, and open interface. The core idea of ​​SDN is to separate the control plane and forwarding plane of network equipment, and centralize the distributed control plane in the traditional network to the SDN controller, so as to realize flexible control of network traffic. With the rapid development of Internet technology, the network structure has become more and more complex, and various network applications have different requirements for the network. Therefore, the possibility of problems in the network has greatly increased, and network maintenance has also become more complicated. As...

Problems solved by technology

However, the above scheme has the following disadvantages: 1) additional traffic monitoring equipment and traffic analysis equipment are required, which increases the complexity of the system, thereby increasing the cost of deployment and maintenance; 2) the SDN controller needs to perform information matching with the SDN forwarding equipment, and Generate group table entries and guide flow table entries; 3) cannot export historical traffic data, cannot generate traffic statistics reports
