Brief description of the drawings：
Fig. 1 is a kind of flow chart of the circuit whole process route computing method of optical transport network of the present invention.
Specific embodiment：
Below in conjunction with the accompanying drawings with specific embodiment to a kind of circuit whole process route computing method of optical transport network of the present invention
It is described further.
Transmission route device type is broadly divided into SDH, MSTP and DWDM, and MSTP equipment is based on SDH expanded functions, therefore will pass
Defeated network route is divided into the calculating of SDH and DWDM device types, and router-level topology algorithm is similar, and device type is different, there is trickle difference
It is different.
The equipment of SDH types annexation in transmission network management system includes interconnection and the species of Topology connection two
Type, interconnection represent the internal port/time slot annexation of network element (equipment), and Topology connection represents the end between network element (equipment)
Mouth annexation.
The equipment of DWDM types annexation in transfers net system connects comprising topology in interconnection, network element (equipment)
The Topology connection three types between network element (equipment) are connect, it is (accurate that interconnection mainly stores board inner port radio frequency channel annexation
To time slot), network element (equipment) interior Topology connection mainly stores the port connection relationship between board, and topology is main between network element (equipment)
Store the port connection relationship between network element (equipment).Annexation between TOM plates and ND2 plates needs spy among interconnection
Different processing.
Refer to the attached drawing 1, a kind of circuit whole process route computing method of optical transport network of the present invention comprise the following steps：
Step 1, starting point two-way search is used as using transmission equipment.Concrete methods of realizing is as follows：
A end and Z end of the SDH types using network element (equipment) port time slot as circuit carry out topology between network element (equipment)
Search, terminate if without result；Carried out if the time slot for adding transparent transmission according to the device port of lookup in the presence of if in network element (equipment)
Interconnection is searched, and takes its network element (equipment) port searched to carry out Topology connection lookup between network element (equipment).Enter in this way
Row recurrence and circulation searching network element (equipment) annexation, untill it can not find out any annexation, by what is found every time
Network element (equipment) link information spliced just obtain to equipment for starting point left and right it is two-way two sections route.Between network element (equipment)
Topology realizes time slot transparent transmission when searching, and network element (equipment) when interior interconnection is searched according to current time slots if search less than needing
Take its high-order time slot or the previous low order time slot of splicing to continue to search for, carried out being split as multiple time slots for multi-slot equipment
Calculating route is proceeded as described above respectively.
SDH type equipments are related to time slot format variation and need alignment processing, and now it is sketched.SDH equipment is usual
The time slot format calculated is shaped like VC4:1-VC12:1, wherein VC4:1 part is as high-order time slot, VC12:1 part is as low
Rank time slot, time slot can be split and be combined as needed, below be carried out time slot format present in circuit router-level topology
List and illustrate, be shown in Table 1：
| Time slot content | Remarks | |
| Form one | VC4:1-VC12:1 | Usual time slot format, actual computation scheme |
| Form two | VC4:1-VC3:1 | Low order time slot VC3 and VC12 equivalent processes |
| Form three | VC4:1 | Only high-order time slot |
| Form four | VC4:1-VC12:1-3 | Low order time slot is multiple and continuous |
| Form five | VC4:1-VC12:33,7,12 | Low order time slot is multiple and discontinuous |
| Form six | VC4:1-VC12:13,24-26,31 | Low order time slot it is multiple it is existing it is continuous also have it is discontinuous |
| Form seven | VC4:3-VC12:5；VC4:5-VC12:1,3,5-6 | High-order time slot is multiple, and low order time slot was multiple both continuous or discontinuous |
Table 1
DWDM types obtain one as starting point using A, Z end network element (equipment) port time slot of circuit and had a try two-way biography
Two defeated routes, the interconnection lookup between network element (equipment) port time slot progress board, the network element (equipment) for taking it to search
Port carries out the interior Topology connection of network element (equipment) and searched.If in the presence of, take its search network element (equipment) port plus transparent transmission when
Gap carries out interconnection lookup, if being searched in the absence of topology between carrying out network element (equipment)；Continue to search for, passed if having result
Return with circulation searching network element annexation, search and terminate if without if, the network element link information found every time is spliced just
Obtain two routes of transmitted in both directions.Specially treated is needed for TOM plates and ND2 plates, is interconnection between the plate, intersection need to be passed through
Annexation is searched, and between other boards is network element (equipment) interior Topology connection, need to pass through network element (equipment) interior Topology connection
Search.
Step 2, the route results for splicing two-way search.Concrete methods of realizing is as follows：
By router-level topology, the circuit of SDH types can obtain two sections of two-way routes, to two sections of route lists progress time
Go through, element position identical value in two lists is spliced, so as to obtain whole routes.
By router-level topology, the circuit of DWDM types can obtain two two-way routes, and Article 2 route is inverted,
So as to obtain whole routes.
Step 3, output routed-format is needed according to application.Concrete methods of realizing is as follows：
By can be calculated whole route, form includes：The structuring of plain text route, each node route, is single
The route of node and a certain section of route, being customized output can be needed according to business scenario.
Embodiment described above is only that the preferred embodiments of the present invention are described, not to the scope of the present invention
