Abstract

The invention provides an SDN route performance testing device and method. The device comprises a matching field distribution module, a data message generation module, a data message matching module and a time information recording module. The invention also discloses an SDN tester. Under the condition that no special measuring protocols and clock synchronizer are included, data messages are identified accurately, each test access point is highly synchronous with a clock, and the accuracy of a transmission performance testing result is ensured.

Description

technical field [0001] The present invention relates to a network path performance testing device and method, in particular to a software-defined network path performance testing device and method. Background technique [0002] Software-Defined Networking (SDN) strips the distributed control plane in the traditional network and puts it in a logically centralized controller, which allows the network status to be obtained directly through the dialog controller; and due to its programmable nature , we can easily realize the unified management of all network devices, and at the same time, we can develop some new functions according to our own needs, such as network diagnosis. However, SDN is still in the early stages of development, and currently there is only one widely used implementation (OpenFlow), and the lack of performance of the controller and the compatibility of network equipment have resulted in no real commercial SDN environment. At the same time, the research and a...
