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...
