Abstract
In the method, initialization configuration is carried on for virtual cascade set first and then virtual reservoir number in the virtual cascade set is automatically adjusted according to each virtual reservior state. The method is used to reduce service interruption posibility greatly.
Description
Technical field
This patent relates to processing method professional in the virtual concatenation group of SDH (Synchronous Digital Hierarchy) (SDH:Synchronous Digital Hierarchy) optical transmission device.
Background technology
In recent years, multi-service transport platform (MSTP:Multi-Service TransportPlatform) technology based on SDH has obtained extensive use in metropolitan area network.The core concept of this technology is organic combination is carried out in the carrying of the basic function of SDH and Ethernet service, two layers of processing.How with the effectively combination of virtual container (VC:Virtual Container) of data service and SDH, wherein the very important point adopts the VC virtual concatenation exactly.But concerning virtual concatenation group, if all can cause the interruption of whole cascaded series business when any one VC alarm occurs or the situation of big error code occurs in the virtual concatenation group.The characteristics that the present invention is directed to virtual concatenation have proposed a solution.
Summary of the invention
Technical problem to be solved by this invention is the influence that overcomes single unavailable VC in the virtual concatenation group, thereby forgo this VC, can utilize other available VC in this virtual concatenation group, utilize operable bandwidth to greatest extent, guarantee that to greatest extent the business in the virtual concatenation group can not interrupted.
Technical scheme of the present invention is: at first virtual concatenation group is carried out initial configuration, adjust the number of virtual container in the virtual concatenation group then according to each virtual container state automatically.
1, dispose in the following manner during initialization:
The time slot configuration situation of all VC in A, the current virtual concatenation group of search, if the time slot of this VC of network management configuration then adds it in virtual concatenation group, even otherwise this VC belongs to this cascaded series, also with its rejecting;
B, all VC that disposed time slot in the virtual concatenation group are joined in the virtual concatenation group, dispose the uplink-downlink configuration of this VC correspondence.
2, normally in service, configuration mode changes as follows:
A, judge whether current VC disposes time slot,, otherwise forward D to if there is time slot just to change next step over to;
Whether B, cascaded series bandwidth are adjusted function automatically and are enabled, if enable then change next step over to, otherwise forward D to;
Alarm and the performance information of current VC in C, the detection virtual concatenation group, when detecting this VC alarm indication signal AIS (AIS:Alarm Indicator Signal) or Loss Of Pointer LOP (LOP:Loss OfPointer) alarm arranged, close the uplink-downlink configuration of this VC, it is rejected from virtual concatenation group, send remote bug indication RDI (RDI:Remote Defect Indicator) to far-end simultaneously; Whether there is error code to surpass threshold value otherwise then detect this VC,, it rejected from virtual concatenation group, send Far End Bit Error indication REI (REI:Remote ErrorIndicator) to far-end simultaneously if surpass thresholding then close the uplink-downlink configuration of this VC; Otherwise then detect this VC whether RDI is arranged,, it is rejected from virtual concatenation group if RDI is arranged then close the uplink-downlink configuration of this VC; Otherwise then detect this VC whether REI is arranged,, it is rejected from virtual concatenation group if REI is arranged then close the uplink-downlink configuration of this VC; If above-mentioned condition does not satisfy, if then this VC once closed in the past, just its uplink-downlink configuration is opened, this VC is joined in the virtual concatenation group;
Whether the VC in D, the cascaded series all detects finishes, if not intact, then detects next.
Adopt method of the present invention, solved the problem that the service disconnection of whole virtual concatenation group appears influencing when unavailable in one of them VC in the virtual concatenation group.Through checking, the unavailable VC that in use can forgo effectively, efficiently is to the influence of virtual concatenation group, and this VC recover normal after, can recover this VC ground use again soon.The use of the method greatly reduces the possibility of service disconnection, has promptly reduced the operation risk of operator, can improve competitiveness of product again.

Embodiment
As Fig. 1, virtual concatenation bandwidth method of adjustment of the present invention is divided into two parts: the one, and the initial configuration of virtual concatenation group; The 2nd, normally in service, adjust the number of VC in the virtual concatenation group, circular treatment automatically according to each vc state.
Fig. 2 shows the initiated configuration method of virtual concatenation group.Remove earlier the sign of closing of all VC in the virtual concatenation group, whether the VC that detects one by one then in the virtual concatenation group disposes time slot, if having, joins in the virtual concatenation group, finishes up to all VC are detected.
Fig. 3 is the bandwidth adjustment figure automatically of virtual concatenation group.
Normally in service, configuration mode changes as follows:
A, judge whether current VC disposes time slot,, otherwise forward D to if there is time slot just to change next step over to.
Whether B, cascaded series bandwidth are adjusted function automatically and are enabled, if enable then change next step over to, otherwise forward D to.
Alarm and the performance information of current VC in C, the detection virtual concatenation group, when detecting this VC alarm indication signal AIS (AIS:Alarm Indicator Signal) or Loss Of Pointer LOP (LOP:Loss OfPointer) alarm arranged, close the uplink-downlink configuration of this VC, it is rejected from virtual concatenation group, send remote bug indication RDI (RDI:Remote Defect Indicator) to far-end simultaneously; Whether there is error code to surpass threshold value otherwise then detect this VC,, it rejected from virtual concatenation group, send Far End Bit Error indication REI (REI:Remote ErrorIndicator) to far-end simultaneously if surpass thresholding then close the uplink-downlink configuration of this VC; Otherwise then detect this VC whether RDI is arranged,, it is rejected from virtual concatenation group if RDI is arranged then close the uplink-downlink configuration of this VC; Otherwise then detect this VC whether REI is arranged,, it is rejected from virtual concatenation group if REI is arranged then close the uplink-downlink configuration of this VC; If above-mentioned condition does not satisfy, if then this VC once closed in the past, just its uplink-downlink configuration is opened, this VC is joined in the virtual concatenation group.
Whether the VC in D, the cascaded series all detects finishes, if not intact, then detects next.
To whole VC detect finish after, delay time one section, the repetition above-mentioned steps detects again.
Fig. 4 is a professional schematic diagram under the virtual concatenation group multi-path transmission in the example.
In virtual concatenation group, comprise 10 VC12 according to mode configuration ethernet business shown in Figure 4 in the virtual concatenation group, to the another one network element, wherein 5 VC12 are by tabula rasa group 1 by multi-path transmission for virtual concatenation group, and other 5 VC12 are by tabula rasa group 2.If when light path 1 and light path 2 were all normal, virtual concatenation group can normally be used 10 VC12, the bandwidth of virtual concatenation group is 20M.When for a certain reason, when light path 1 was intercepted as shown in the figure, the method for the application of the invention can be rejected the influence of 5 VC12 of light path 1 rapidly, and the bandwidth of virtual concatenation group is reduced to 10M (only using 5 VC12 of light path 2) automatically.When light path 1 recover normal after, virtual concatenation group again can be automatically added 5 VC12 of light path 1 in the cascaded series to, bandwidth becomes 20M.
When any one VC12 error code occurred and transfinites in detecting cascaded series, the present invention also can close this VC12 automatically, and the assurance business is not subjected to that single VC12 is abnormal to be influenced, as long as professional have a VC12 to talk about normally, and can both normal operation.
