Ethernet performance testing method and device based on point-to-point testing

Abstract

The invention discloses a method and device for testing Ethernet real-time service quality on the basis of point-and-point testing, and belongs to the field of Ethernet performance testing. According to the method, testing data packets with timestamp values are sent back and forth between a master device and a slave device, so that measurement of a one-way delay value and one-way delay jitter is achieved, and synchronous operation is accomplished; according to the device, the master device and the slave device are connected through an intermediate network, the master device is used for generating the testing data packets and leading the testing process, the salve device is used for receiving the data packets, and the testing process of the slave device is controlled by the master device. According to the method and device, due to the fact that delay measurement of the master device and delay measurement of the slave device are carried out according to relative clock adjustment of the master device and relative clock adjustment of the slave device respectively, the synchronizing process of the testing time can be accomplished in two steps, a whole network synchronous clock is not needed, special processing of a middle node device is not needed, the testing environment is simplified, precision, achieved by hardware, of a local timer can be at the microsecond level, and the testing process does not have any influence on the normal service.

Description

technical field [0001] The invention relates to the field of Ethernet performance testing, in particular to an Ethernet performance testing method and device based on point-to-point testing. Background technique [0002] Today, Ethernet transmission technology has gradually developed into the network of choice for people, and the focus of network applications has changed from just transmitting data in the past to providing entertainment applications and new applications in the interconnected environment. Ethernet-based services such as mobile backhaul, business services, and large-scale services need to carry a variety of applications such as voice, video, email, online transactions, and more. [0003] Generally speaking, network information flow can be divided into three categories: data information flow, real-time information flow, and high-priority information flow. Since each type of information flow is affected by network characteristics differently, each type of inform...
