Embodiment Construction

[0047] As mentioned in the background art, how to obtain the network service quality analysis information of packets in the SDN network is a problem generally concerned by those skilled in the art.

[0048] Therefore, the present invention receives the user message sent by the SDN switch through the SDN controller, obtains the protocol type in the user message, and the SDN controller notifies the SDN switch to test according to the protocol type, and then the SDN switch measures the network quality in the message forwarding process information, and report it to the SDN controller. The SDN controller analyzes the information based on the obtained network quality to better provide network service quality. For example, the forwarding path of the message can be optimized according to the transmission delay of the message, and the packet loss rate, etc.

[0049] The implementation of the present invention will be described below through specific examples and in conjunction with the...

Abstract

The invention discloses a network quality analysis method based on SDN and a SDN system. The analysis method comprises the following steps: a SDN controller receiving a user message sent by a SDN switch, acquiring a protocol type in the user message; the SDN controller notifying the SDN switch to test according to the protocol type; the SDN switch measuring the network quality information in the message forwarding process, and reporting to the SDN controller to finish the testing. The network service quality analysis information of the message is acquired, thereby preferably providing the network service.

Description

technical field [0001] The invention relates to the technical field of SDN network, in particular to an SDN-based network quality analysis method and an SDN system. Background technique [0002] In data communication networks, network service quality analysis is very important and commonly used. Service quality analysis includes bandwidth, packet loss rate, message transmission delay, etc. Traditional test methods construct test packets through test instruments, and obtain network performance and network quality parameters provided to users by analyzing test packets, such as transmission delay, transmission rate, etc. service quality analysis, and cannot optimize the data forwarding path, such as figure 1 shown. [0003] SDN (Software Defined Network) is an emerging software-based network architecture and technology, and its core technology is OpenFlow technology. The core technology of SDN, OpenFlow, separates the network device control layer and data layer. The SDN con...
