Problems solved by technology

The root cause of this problem is that the G node cannot automatically insert the AIS according to the LTC. In addition, for the relationship between different levels of TCM functions and the setting of the relationship with the cross-connection, such as which TCMs are implemented before the cross-connection and which ones are implemented after the cross-connection Realization, which TCMs affect other TCMs or are affected by other TCMs, will lead to different TCM monitoring ranges and different protection switching results, and some of the results are correct and desir

Embodiment 1

[0078] FIG. 4 is a structural diagram of a device for monitoring network quality in Embodiment 1 of the present invention, including a branch unit 1 , an ODU cross unit 2 , a line unit 3 , a splitter unit 4 and a multiplexer unit 5 . The branch unit 1 and the line unit 3 are collectively referred to as a monitoring control module. In the present invention, the monitoring and control module mainly executes various functions of the present invention to monitor network quality. Referring to Fig. 4, the monitoring control module may be at least one branch unit and / or at least one line unit.

[0079] Referring to Figure 4, the branch unit 1 receives the signal sent by the client side during the uplink service, performs adaptation and inserts the overhead and then sends it to the ODU crossover unit 2; during the downlink service, receives the signal sent by the ODU crossover unit 2, After performing de-adaptation and terminating the overhead, it is sent to the client side. It also...

Embodiment 2

[0137] In this embodiment, the network shown in FIG. 7 is taken as an example to specifically describe the method for monitoring network quality by using the TCM.

[0138] In Figure 7, there are 16 nodes from A to P. The part enclosed by the oval indicates that this part belongs to a certain domain. This domain generally refers to a certain operator, and it can also be any part of the user who wants to be divided and can carry out signal independently. Network scope for quality monitoring. The three domains included in this embodiment are: domain 1 includes node BCDFGH, domain 2 includes FGHJKL, and domain 3 includes GHKL. Among them, service A goes from node A to node E, F, G, H, L, and finally to node P, as shown by the thick solid line in the figure, and service B is a two-way service, one direction is from node A to node B, F, J, N, O, finally to node P, the other direction from node P via nodes O, N, J, F, B, and finally to node A, as shown by the short dashed line in th...

Abstract

The present invention discloses a method for monitoring the network quality, which comprises the steps of: prearranging series-connection monitoring at the network node equipment, arranging the successor action enabling with a lost series-connection or avoiding and/or enabling or avoiding the series-connection of each level, and doing series-connection monitoring by the network equipment with the prearranged content. The present invention also discloses a device for monitoring the network quality, which includes the following component: a monitoring control module which is used to prearrange the series-connection monitoring, arranging the successor action enabling with a lost series-connection or avoiding, and/or, enabling or avoiding the series-connection of each level, and doing series-connection monitoring with the prearranged content. The invention can increase the accuracy of monitoring the network quality.

Description

technical field [0001] The invention relates to network monitoring technology, in particular to a method and device for monitoring network quality. Background technique [0002] There are many different network operators all over the world. They each have their own laid optical fibers and network equipment. Within their own subnets, the operators themselves are fully responsible for the management, maintenance, and fault location of network equipment. However, in order to obtain greater coverage, it is necessary to connect network devices of multiple different operators to form a larger network to serve users. In this case, an end-to-end user service may be transmitted through subnets of multiple different operators. At this time, there needs to be some mechanism capable of distinguishing the quality conditions of the respective networks of different operators. [0003] In order to be able to evaluate the network quality of subnets of different operators, the concept of Ta...
