Packet transport network service detecting and measuring method, device and system

Abstract

The application brings forward a packet transport network service detecting and measuring method, device and system, and relates to the realization and application field of a packet transport network service test technology. The method comprises the steps: sending a data stream to access loopback equipment through a packet transport network (PTN), the data stream including a test message formed according to a preset condition; receiving a loopback message returned by the access loopback equipment through the PTN; and determining the bandwidth quality of a current PTN link according to the flow of the sent data stream and the flow of the received loopback message. The method checks the correctness of service configurations, enables a user to conveniently make fault diagnosis for PTN services, and helps to ensure that the quality of services actually provided to a user is as good as what a service provider promises to the user when the user is buying the services.

Description

Technical field [0001] The present invention relates to the realizing application field of PTN (Packet Transport Network, packet transport network) service test technology, in particular to a method, device and system for packet transport network service detection and measurement. Background technique [0002] With the rapid rise of mobile Internet services, PTN (PacketTransport Network, packet transport network) networks are widely used in various operators. PTN equipment with more Ethernet characteristics is used in large quantities. The opening and management put forward higher requirements. At present, it is difficult to start the PTN business, and there is a lack of necessary test methods and technologies to detect the business configuration to ensure that the quality of the service actually received by the user is consistent with the operator's commitment to the user at the time of purchase. Moreover, in the process of PTN business operation, in addition to QoS (Quality of...

AI Technical Summary

Problems solved by technology

At present, the deployment of PTN services is relatively difficult, and there is a lack of necessary test methods and technologies to test service configurations, so as to ensure that the service quality actually obtained by users is consistent with the operator's commitment to users at the time of purchase.

Moreover, in the process of PTN business operation, in addition to guaranteeing the user's SLA (Service-Level Agreement, service level agreement) through technologies such as QoS (Quality of Service, service quality) and protection switching, there is a lack of a technology and method that can provide service performance indicators to verify whether it meets the SLA signed with the user

At present, generally speaking, PTN service tests are completed with special test and measuring instruments. The use of these instruments is relatively complicated and requires high technical level of users.

Therefore, operators need to purchase expensive meters and have special personnel responsible for them, which is costly

On the other hand, both ends of the PTN service need to coordinate operations, and sometimes need to interrupt user services. The efficiency of service detection and fault location is low, and the maintenance personnel have high requirements for troubleshooting themselves, and the maintenance cost of the PTN network is also high. raised
