Example Embodiment

[0041] Embodiment 1: This embodiment is for a one-way performance measurement situation. Figure 1 is a schematic diagram of the network performance measurement method of Embodiment 1 of the present invention. The source node A sends an OAM message to the destination node D, and the destination node D performs the measurement as a measurement node. Network performance measurement based on OAM messages to obtain one-way performance indicators between the source node A and the destination node D. Commonly, the clock synchronization between the source node A and the measurement node D is maintained.

[0042] Fig. 2 is a flowchart of the network performance measurement method according to the first embodiment of the present invention. Before the measurement starts, the destination node D presets its own measurement period T. The network performance measurement method according to the first embodiment of the present invention includes:

[0055] Embodiment 2: This embodiment is for a one-way performance measurement situation. FIG. 3 is a schematic diagram of a network performance measurement method of Embodiment 2 of the present invention. The OAM message sent by the source node A to the destination node D passes through the intermediate node B and the intermediate node C is forwarded to destination node D. Intermediate node B is used as a measuring node to perform network performance measurement based on OAM messages to obtain one-way performance indicators between source node A and intermediate node B. Commonly, source node A and measurement node B Keep clock synchronization between.

Abstract

The method includes steps: continuous receiving at least one operation, administration and maintenance (OAM) message carried with sending time stamp from source node, measurement node records time stamp of receiving OAM message, saves the sending time stamp carried by OAM message, and self recorded receiving time stamp; based on saved sending time stamp and receiving time stamp, measurement node calculates network performance index. Without need of inpouring probe message to network, the method can keep consistent network performance index between performance measure period and not performance measure period so as to raise accuracy for measuring network performance.

Description

technical field [0001] The invention relates to network performance measurement technology, more specifically, to a network performance measurement method based on operation, administration and maintenance (OAM) messages. Background technique [0002] In order to improve network service quality, current network operators will regularly conduct network performance measurement and submit performance measurement reports to users, so that users can truly understand the network service level, thereby improving user service satisfaction. At the same time, the results of performance measurement are also helpful. For network operators to better maintain the network. According to current protocols, indicators used to measure network performance usually include: time delay (TD), delay jitter (DV), packet loss rate (LR) and unavailability (UA), etc. [0003] In the prior art, when performing network performance measurement, a performance measurement message is usually specially constr...
