Embodiment
The OTN cluster skewing mechanism of the embodiment of the present invention as shown in Figure 1, mainly comprises one or more business subrack, one or more intersection subrack, business subrack with intersect between subrack and can be connected by interconnection line.As: service board is connected with interconnect crosspoint plate, and interconnect crosspoint plate is then undertaken interconnected by the interconnection line such as optical fiber, cable between subrack (or each cross board intersected in subrack) with intersecting, and realizes business subrack and intersects the business transmission of subrack.Certainly, interconnect crosspoint plate also can independently be arranged, and can be positioned at business subrack and also can be positioned at intersection subrack; And business subrack (or each service board in business subrack) is connected with interconnect crosspoint plate by interconnection line, interconnect crosspoint plate is then undertaken interconnected by interconnection line between subrack (or each cross board intersected in subrack) with intersecting.In addition, business board also can be connected by other means with interconnect crosspoint plate.
Specifically, business subrack is primarily of service board (quantity is one or more) and interconnect crosspoint plate composition.See Fig. 2, the side of service board is light mouth, is connected with client or OTU transmission equipment, and opposite side is electric mouth, the business of electric mouth can pass through backboard, cable or other modes and interconnect crosspoint plate mutual.
It should be noted that in traditional cross system, there is no interconnect crosspoint plate.Interconnect crosspoint plate in the embodiment of the present invention is different from traditional cross board, and traditional cross board is mainly used in dispatching services, and the engagement plate that interconnect crosspoint plate is equivalent to business subrack and intersects between subrack.Such as: the business from service board enters interconnect crosspoint plate, by interconnect crosspoint plate business gathered and interweave, the object interweaved each business can be evenly distributed to intersect on each cross board of subrack, and the business after intertexture is redistributed to corresponding cross board.In addition, the business carrying out Self-crossover subrack enters interconnect crosspoint plate, carries out deinterleaving by interconnect crosspoint plate to business, will be assigned to corresponding service board after the Service recovery of intertexture;
Subrack of intersecting forms primarily of cross board (quantity is one or more).Cross board carries out bit slice cutting and scheduling to the business from business subrack, thus realizes the timeslot scheduling of business.Cross board in the embodiment of the present invention can dispatch the business that multiple difference is intersected between subrack.
Show the cluster device comprising two business subracks and three intersection subracks see Fig. 3, Fig. 3, through this cluster device, cross-capacity can be 2 times during business sheet subrack.Setting business subrack number is m=2, and the subrack number that intersects is n=3.Usually, the relation between m and n meets following two requirements: 1) cross-capacity of n intersection subrack is more than or equal to the volume of business of m business subrack; 2) the maximum time slot bit slice number that cross unit number <=all cross chips of cross board number × each cross board of n × each intersection subrack can cut.
Describe known in conjunction with above, the present invention realizes operation thinking that OTN cluster intersects can represent flow process as shown in Figure 4, and this flow process comprises the following steps:
Step 410: for the service board and the cross board that form cluster, by interconnect crosspoint plate, the business between described service board and cross board is interweaved or deinterleaving process.
Step 420: interconnect crosspoint plate will complete the traffic assignments of described process to corresponding service board or cross board.
Visible in sum, no matter be method or the device comprising service board and cross board, the present invention realizes the technology that OTN cluster intersects, and can realize ultra-large cross-capacity by OTN service board and cross board cluster.Supposing in conventional cross system one, to intersect the limit cross-capacity that subrack can accomplish be aT (T is the unit of cross-capacity), if so the present invention realize OTN cluster intersect device have n business subrack, the capacity of each business subrack is identical with the capacity of intersection subrack single in conventional cross system, then the present invention realizes the device that OTN cluster intersects and makes cross-capacity expand n doubly, becomes n*aT.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
