Description
Technical field
The utility model relates to the technical field of OTN network protection rings, especially a kind of protection rings based on the G.873.1 OTN network of specification.
Background technology
Along with the development of the communication technology and the sharp increase of traffic demands, network transmission speed is more and more faster, and capacity is increasing.OTN mesh network assume responsibility for the transformation task on backbone network, it can provide the one-tenth of the huge network bandwidth, stable performance and cheapness originally to support the current and following any business and signal, becomes and supports the infrastructure the most flexibly and effectively of Next Generation Telecommunication Networks and the direct supplier of new wavelength business.
Along with the dependence of modern society to communication is increasing, any one network failure all may cause economic loss difficult to the appraisal.Efficiently, stable, flexibly optical network protection means are the prerequisite features of New Generation Optical network.Existing optical network protection means are mainly protection & restoration two kinds, and the former uses comparatively extensive.Conventional network protection method is divided into line protection reverse and ring protection to switch, and two kinds of modes are widely used in existing OTN equipment.
But along with OTN network topology becomes increasingly complex, existing line protection reverse and ring protection switch the demand that gradually can not meet mesh topology protection.1998, a Canadian scholar proposed the special protection algorism of mesh network---and P encloses algorithm.This algorithm thinking is novel, and protective efficacy is high, is a kind of protection algorism being specifically designed to mesh network.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provides a kind of protection rings based on the G.873.1 OTN network of specification.
The utility model solves the technical scheme that its technical problem adopts: a kind of protection rings based on the G.873.1 OTN network of specification; there is root optical fiber between two; they are respectively outer ring optical fiber and inner ring optical fiber, described every root optical fiber has two wavelength at least, and occurs in pairs.
Further restriction, the outer ring optical fiber described in technique scheme has the operation wavelength F1 be positioned at above outer ring and the protection wavelength P1 be positioned at below inner ring; Described inner ring optical fiber has the operation wavelength F2 be positioned at above inner ring and the protection wavelength P2 be positioned at below outer ring.
Further restriction, the network signal transmission direction of the outer ring optical fiber described in technique scheme is contrary with the network signal transmission direction of inner ring optical fiber.
Further restriction, the network signal transmission direction of the outer ring optical fiber described in technique scheme is that the network signal transmission direction of described inner ring optical fiber is counterclockwise clockwise.
The beneficial effects of the utility model are: a kind of protection rings based on the G.873.1 OTN network of specification of the present utility model, it is one distinctive protection form on OTN network, apply comparatively extensive, can the protection shared network of highly effective and safe, the feature had is: 1, two subrings work/protection relation each other, and business can be configured in any subring; 2, business can two-way flexible configuration, and resource utilization is high; 3, switching of passage/passage group level is needed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of protection rings based on the G.873.1 OTN network of specification of the utility model as shown in Figure 1, have root optical fiber between two, they are respectively outer ring optical fiber and inner ring optical fiber, described every root optical fiber has two wavelength at least, and occurs in pairs.Wherein, described outer ring optical fiber has the operation wavelength F1 be positioned at above outer ring and the protection wavelength P1 be positioned at below inner ring; Described inner ring optical fiber has the operation wavelength F2 be positioned at above inner ring and the protection wavelength P2 be positioned at below outer ring.The network signal transmission direction of described outer ring optical fiber is contrary with the network signal transmission direction of inner ring optical fiber.The network signal transmission direction of described outer ring optical fiber is that the network signal transmission direction of described inner ring optical fiber is counterclockwise clockwise.
When the working service AC on the fiber optic wavelength of outer ring is when breaking down across section AB and BC, this business is switched on the wavelength of inner ring optical fiber by Air conduct measurement point A and C, completes the protection to this business.And the business CA on inner ring fiber optic wavelength is also in like manner, transmitted by the protection wavelength of outer ring.Like this, by two optical fiber and two wavelength, just achieve the pretection switch of optical network service, and without the need to the wavelength shifter of costliness.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
