Embodiment Construction

[0061] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0062] The embodiment of the present invention provides a kind of packet loss measurement method that is used for SPN network IOAM function, and it is used for carrying out the packet loss measurement to the monitoring flow that has the two-color marking block that intersperses with each other, comprises the following steps:

[0063] Send the 1588 time synchronization protocol configuration to the SPN devices in the entire network, so that the system time of all SPN devices and each single disk of the distributed device can reach the time synchronization state;

[0064] Select the input side or output side of several nodes through which the monitoring flow passes as the measurement point, and issue IOAM configuration information respectively. The IOAM configuration information includes acquisition cycle, offset time and measurement point locatio...

Abstract

The invention discloses a packet loss measurement method and system for an IOAM function of an SPN network, relates to the technical field of communication. The packet loss measurement method and the system realize coordination and consistency of mark switching action and data acquisition action of each single disk of each equipment through adopting a scheduling method based on time synchronization, ensure alignment processing of the performance data points of the same mark block among the equipment, and solve the problem of synchronization and coordination of performance acquisition actions and mark switching actions among the equipment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a packet loss measurement method and system for the IOAM function of an SPN network. Background technique [0002] SPN (Slicing Packet Network, Slicing Packet Network) is a new generation of multi-service integrated bearer network oriented to 5G. The in-band detection function of service flow is a necessary means for intelligent operation and maintenance of SPN network, among which packet loss measurement is the most basic service. The flow in-band detection function can monitor the service quality and locate faults in real time from the perspective of end-to-end, link-by-segment, or node-by-node. The SPN network adopts the IOAM technology combined with the timing cycle alternate marking method to realize the in-band packet loss detection function of the detected service flow (monitoring flow). The principle of end-to-end packet loss measurement is as follows: figure 1 s...
