Method for detecting transmission delay and related equipment

Abstract

The embodiment of the invention discloses a method for detecting transmission delay and related equipment. One of the methods comprises the following steps: enabling destination end routing equipmentto receive a first IP data message sent by source end routing equipment, wherein the first IP data message carries a first timestamp of sending the first IP data message by the source end routing equipment; according to the first timestamp and a second timestamp of the destination end routing device for receiving the first IP data message, calculating one-way transmission delay from the source endrouting device to the destination end routing device. Therefore, Ethernet data service transmission channel resources are saved, and the service channel use efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to Ethernet technology, and more specifically relate to a method and related equipment for detecting transmission delay. Background technique [0002] The current Ethernet technology has been widely used in the transmission system due to its good economy, interoperability and ease of use. With the rapid development of carrier-class Ethernet technology and standards, Ethernet gradually extends to the metropolitan area network and wide-area network, and then provides multi-service bearer as a carrier-class transmission technology. The complexity of Ethernet technology in network operation continues to increase, and its functions continue to increase. The core data switching technology has developed from simple circuit switching to layer 2 switching, and from layer 2 switching to today's more mature layer 3 switching. The different Ethernet network layers have different requirements on th...

[0007] 1. For the Ping mode, the IP address configured on the network device is pinged on the host, because generally a slightly high-end network device will be protected by the CPU (Central Processing Unit, central processing unit) of the control layer, and the response processing of this ping packet is given priority The level is very low, so the delay test value is generally high or even packet loss occurs, but this does not reflect the real network performance, and on many network devices, IP packets with option fields also need to be sent CPU processing will also cause a high delay in the test;

[0008] 2. For the DMM / DMR message mode, the DMM / DMR control message and the data service message share the transmission channel. When the traffic is congested or overloaded, it is easy to be adjusted by QoS (Quality of Service) and even discarded.

Thus affecting the accuracy of delay statistics
