Frame loss measuring method, frame loss measuring device and frame loss measuring system

Abstract

The invention discloses a frame loss measuring method, a frame loss measuring device and a frame loss measuring system, which are used for realizing message counting in LM (Loss Measurement) through the counting function of a switch chip port, realizing the LM through a CPU (Central Processing Unit) and increasing measuring accuracy. The frame loss measuring method provided by the invention comprises the following steps of: informing a monitoring port on a switch chip of counting message quantities in an input direction and an output direction respectively; transmitting an access control list (ACL) rule to the switch chip, wherein the ACL rules specifies the types of messages required to be counted by the monitoring port in the input direction and the output direction respectively; acquiring the message quantity counted in the input direction and the message quantity counted in the output direction through the monitoring port on the switch chip; and determining the quantity of lost frames on network equipment according to the message quantity counted in the input direction and the message quantity counted in the output direction.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method, device and system for measuring frame loss. Background technique [0002] The Operation Administration Maintenance (OAM) function is very important in the public telecommunication network, it can simplify the network operation, test the network performance and reduce the network operation cost. In a network that provides guaranteed quality of service, the OAM function is particularly important. At present, operators have a sharp increase in the demand for the OAM function of their respective networks, and international standard organizations such as the International Telecommunication Union Telecommunication Standardization Sector (ITU Telecommunication Standardization Sector, ITU-T) and the Internet Engineering Task Force (Internet Engineering Task Force, IETF) require The OAM standard has been formulated. At present, ITU-T Y.1731 is a more comprehensive prot...

Problems solved by technology

In the prior art, there are switching chips that realize the LM function through hardware, but for product lines that are very cost-sensitive, the cost of purchasing such chips is very high, and independent development also requires a lot of manpower and financial resources

[0029] To sum up, in the prior art, the CPU cannot complete the counting of TxFCl and RxFCl for realizing the LM function, and the cost of realizing the LM function through hardware is relatively high
