Problems solved by technology

[0008] In this method, the difference between the receiving time and the sending time includes the processing time of the nodes in the RPR ring network to the echo message, such as the processing time of the CPU in the node. The transmission delay of the RPR ring network is large, so that the link evaluation parameters such as transmission delay and jitter of the link in the RPR ring network are inaccurate

Embodiment Construction

[0042] Link evaluation parameters are important parameters for evaluating link transmission performance. In order to improve the accuracy of link evaluation parameters, it is necessary to fully consider the RPR (Resilient Packet Ring) ring network when determining the link evaluation parameters of data packet transmission links. The processing time of the nodes in the data packet.

[0043] The core of the present invention is: the sending node sends each request data message to the peer node, and the sending node obtains the sending time of sending each request data message, the receiving time of receiving the response data message returned by the peer node, and the peer pair For the processing time of each request data message and response data message, the sending node determines link evaluation parameters according to the sending time, receiving time, and processing time.

[0044] The technical solution provided by the present invention will be further described below based...

Abstract

The invention supplies a method to gain the link evaluate parameter based on elasticity group circle. It sends data file to end node from sending node, the sending node gaining the sending time, receiving time of responding data file, and process time to the data report and responding data report. The link evaluate parameter would be determined by the sending time, receiving time, and process time. The invention could rapidly and accurately determine the link evaluate parameter and improve the RPR circle network maintainability.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for acquiring link evaluation parameters based on an elastic grouping ring. Background technique [0002] RPR (Resilient Packet Ring) technology integrates the intellectualization of IP (Internet Protocol), the economy of Ethernet, and the high bandwidth efficiency and reliability of optical fiber ring network, providing broadband IP metropolitan area network operators with A good networking solution. [0003] RPR technology makes it possible for operators to provide carrier-class services at low cost in the metropolitan area network, and it reduces transmission costs while providing SDH (Synchronous Digital Hierarchy)-level network reliability. The most attractive feature of RPR, which is different from traditional MAC (Media Access Control), is that it has carrier-class reliability. RPR is not limited to processing data-oriented service transmission requ...
