Embodiment
The embodiment of the invention provides a kind of method of obtaining end-to-end circuit information in the network management system, the data that the data that this method derives according to the producer webmaster and the Corba interface of producer's webmaster provide are obtained the end-to-end circuit information that can use for the various application of network management system.Below in conjunction with Figure of description the embodiment of the invention is described in further detail, referring to Fig. 2, detailed process is as follows:
Step 201: the resource information of obtaining end-to-end circuit.
Transmission network management collects the resource information of the whole network by the Corba interface, and described resource information comprises that network element, port, machine dish, PTP, CTP, time slot, interconnection, topology connect the information that is connected with subnet etc.The information that has also comprised Virtual NE in these resource informations, Virtual NE is meant and is present in same producer, by plural Element management system (Element Management System, EMS) network element of management simultaneously.In the side circuit, this network element should only belong to an EMS management, only exists in other EMS because certain particularity is arranged for it.Such as, in order to write down a complete circuit information of striding a plurality of EMS management, need in an EMS, write down under this circuit at border network element that another EMS managed, this border network element is not the true network element of this EMS management, its configuration information, intersection information such as this network element, configuration information when being networking, when again transmission network being adjusted, the information of this network element only changes under its actual place EMS, and the configuration information about this network element all no longer changes among all the other EMS.
Transmission network management can collect the information of this network element during from the Corba northbound interface image data of producer's webmaster from different EMS, be real but have only the information of this network element that an EMS reports, and remaining all is false.When carrying out the circuit serial connection, if do not get rid of this class deceptive information, will cause data corruption, will be influential to sequential circuit.Therefore the information that these Virtual NE are arranged in SNMS after the information of derivation Virtual NE, will could obtain the resource information of end-to-end circuit accurately behind the information deletion of these Virtual NE from SNMS.
Step 202: in end-to-end circuit, select a network entity as the current network entity arbitrarily, and obtain the information of current network entity in the resource information of the end-to-end circuit that from step 201, obtains.Can select any one network element as the current network entity in this step, perhaps select subnet to connect that (Sub-network Connection, SNC), the network element of the starting point that this subnet is connected is as the current network entity.When the information that gets access to the former end of circuit paths from producer's network management system, just the starting point network element that producer's network management system can derived circuit and this circuit also can select described source end as the current network entity when the initial port information of this network element.
Step 203: the information of record current network entity, network element, port, machine dish, PTP, CTP, time slot, interconnection, the topology that comprises the current network entity connect the information that is connected with subnet etc.
Step 204: according to the information of current network entity, determine the all-network entity be connected with the current network entity, and obtain the information of described all-network entity in the resource information of acquisition from step 201.
In transmission network, have many circuit routes and will pass through the current network entity, therefore have a plurality of network entities and link to each other, also may have only a network entity to be connected certainly with the current network entity with the current network entity.
The path of a circuit generally is according to circuit source end-interconnection-topology connection-interconnection in transmission network ...-interconnection-circuit place this principle of end is carried out the circuit serial connection, therefore according to the information of described current network entity, carry out one or more network entities that interconnection and the sequential search that is connected of topology are connected with described current network entity, thereby from resource information, obtain the information of described one or more network entities.
From step 201, get access to all topology link informations of obtaining the current network entity in the resource information, here the topological link information that gets access to can be a topological link information, also can be many topological link informations, the information that has comprised a network entity identical in every topology link information with the PTP information of current network entity, like this, according to every topological link information obtain one with the topological network entity that is complementary that is connected of current network entity.The topology link information of current network entity has one or more of, therefore has one or more network entities to be connected with the topology of current network entity and is complementary.
Network entity inside be connected to interconnection, when carrying out circuit serial connection coupling, determine a network entity and current network entity topological be connected be complementary after, also need the cross-coupled source end CTP of this network entity and the cross-coupled place end CTP of current network entity are mated, determine the CTP information between current network entity and this network entity.
When if the CTP of the cross-coupled Su Duan of the cross-coupled source end CTP of this network entity and current network entity is identical, then this network entity and current network entity low order interlace algorithm are mated.The place end CTP "/sts3c_au4-j=3/vt2_tu12-k=1-1=4-m=3 " of current network entity for example, and the source end CTP "/sts3c_au4-j=3/vt2_tu12-k=1-1=4-m=3 " of this network entity, then this network entity and current network entity are 2M low order interlace algorithm coupling, then, from resource information, know the CTP information of this network entity and current network inter-entity.Here, this network entity and current network entity situation also may occur, just no longer describe in detail for 34M low order interlace algorithm coupling.
When if the CTP of the cross-coupled source end CTP of this network entity and the cross-coupled Su Duan of current network entity can not be identical, need that then this network entity and current network entity are carried out high-order and intersect break-through and mate.The place end CTP "/sts3c_au4-j=3/vt2_tu12-k=1-1=4-m=3 " of current network entity for example, and the source end CTP "/sts3c_au4-F=3/ " of this network entity, then this network entity and current network entity high-order cross-matched, this network entity and current network entity are 155M high-order cross-matched, then, from resource information, know the CTP information of this network entity and current network inter-entity.
