Embodiment
Basic thought of the present invention is: when creating teleservice, if professional end points network element belongs to same EMS, the task of then will calculate minimum weights route between the end points network element is handed down to this EMS; If professional end points network element does not belong to same EMS, then the NMS EMS that triggers professional end points network element place calculates end points network element that EMS comprises to the minimum weights route between the network element of border, and trigger other EMS and calculate minimum weights route between the border network element that EMS comprises, afterwards, EMS reports NMS with result of calculation, and NMS is the minimum weights route of the NMS layer between the computing service end points network element again.
Below, be described with reference to the accompanying drawings the realization of P 2 P service establishing method of the present invention by specific embodiment.
Fig. 1 is a P 2 P service establishing method schematic flow sheet of the present invention, and as shown in Figure 1, this method comprises:
Step 101: when trigger creating teleservice, two end points network elements that NMS judges the teleservice of being created whether in same EMS, if, execution in step 102; Otherwise, execution in step 103.
Wherein, specifically how to trigger to create teleservice and how to judge whether the end points network element is in and all belong to known technology in the same EMS, repeat no more here.
Figure 2 shows that a network topology structure that has three EMS, every topology connection all has corresponding weights.With network topology structure shown in Figure 2 is example, is chosen in to create a teleservice between network element A shown in Fig. 2 and the network element Z, and in order to simplify description, constraint is not considered to route here.
At this moment, step 101 is specially: when triggering creates NE A during to the teleservice of network element Z, NMS judges network element A and network element Z whether in same EMS, if, execution in step 102, otherwise, execution in step 103.
Because network element A and network element Z be in an EMS in the topological structure shown in Figure 2, therefore, with execution in step 103.
Step 102:NMS triggers the minimum weights route of EMS layer between the affiliated EMS calculating two-end-point network element of end-to-end business end network element, carry out the establishment of teleservice route according to this minimum weights route, preserve the detailed routing iinformation of the teleservice of creating, and return the establishing route results messages to NMS, current handling process finishes.
Wherein, in the described establishing route results messages, EMS only need notify the NMS route whether to create success, need not to report concrete routing iinformation.
Step 103:NMS triggers two EMS under two end points network elements of teleservice respectively, calculates the EMS layer minimum weights route of self-contained end points network element to self all border network element; Simultaneously, NMS triggers the minimum weights route of EMS layer between per two the border network elements of EMS calculating self that do not comprise teleservice end points network element.
Specific to embodiment illustrated in fig. 2, the EMS under the NMS triggering network element A calculates network element A to the minimum weights route of the EMS layer of all border network elements of this EMS, also triggers the affiliated EMS of network element Z and calculates network element Z to the minimum weights route of the EMS layer of all border network elements of this EMS; Simultaneously, NMS triggers the minimum weights route of EMS layer between per two the border network elements of EMS calculating EMS self that do not comprise network element A or network element Z.
Step 104: the calculation task that each EMS parallel computation NMS issues reports NMS with the end points network element and the minimum weights of the minimum weights route of all the EMS layers correspondences that calculate.
Specific to embodiment illustrated in fig. 2, comprise 2,6,7 three border network elements of network element among the EMS under the network element A, therefore, EMS will calculate network element A to the minimum weights route of the EMS layer of 2,6,7 three border network elements of network element under the network element A.As shown in Figure 3, network element A is a network element A-network element 1-network element 2 to the minimum weights route of the EMS layer of network element 2, PROP[A-2] (expression network element A and 2 abstract weights that are connected) be 2; Network element A is a network element A-network element 3-network element 7 to the minimum weights route of the EMS layer of network element 7, PROP[A-7] be 2; Network element A is a network element A-network element 6 to the minimum weights route of the EMS layer of network element 6, PROP[A-6] be 40;
Do not comprise among the EMS of network element A and network element Z and comprise 9,15,16 3 border network elements of network element, therefore, calculate 9,15,16 3 border network elements of network element minimum weights route between any two, as shown in Figure 3, suppose PROP[9-16] be 3, PROP[9-15] be 4, PROP[15-16] be 3.
In this step, after each EMS finishes the calculation task that NMS issues, each EMS need not to report the details of the minimum weights route of EMS layer that calculates, that is: need not to report the concrete route of EMS layer between the network element to connect, only need corresponding two the end points network elements of the minimum weights route of EMS layer and the minimum weights of the minimum weights route of this EMS layer of reporting to get final product.
Wherein, the details of the minimum weights route of each EMS layer can directly be preserved by each EMS, so that in step 106, when NMS gave corresponding EMS with the part route sending-down of the minimum weights route of NMS layer, EMS can carry out the establishment of EMS layer route faster.
Thus, in this step, after three EMS shown in Figure 2 calculate the minimum weights route of above-mentioned EMS layer respectively, only need two end points network element-network element A corresponding of network element A for example and network element 2 and minimum weights 2 to report NMS with the EMS layer minimum weights route between the network element 2, perhaps, network element A and network element 7 and minimum weights 2 are reported NMS; The minimum weights route of other EMS layers reports with reference to above-mentioned report method.
Wherein, the minimum weights route of EMS layer how each EMS calculates between self-contained two network elements belongs to known technology, repeats no more here.
Weights information between two border network elements that are under the jurisdiction of different EMS of end points network element, minimum weights and the NMS storage of the minimum weights route of the EMS layer correspondence that the EMS that step 105:NMS basis receives reports, create NMS layer network topological structure, calculate the minimum weights route of NMS layer between the teleservice two-end-point network element.
Receive the end points network element and minimum weights of the minimum weights route of the EMS layer correspondence that each EMS reports as NMS after, in conjunction with the weights information of self preserving between two border network elements that are under the jurisdiction of different EMS, set up the network topology structure of NMS layer, as shown in Figure 3, carry out abstract connection between two end points network elements of the minimum weights route of EMS layer correspondence.Afterwards, NMS calculates the minimum weights route of NMS layer between network element A and the network element Z, supposes that the minimum weights route of NMS layer between network element A and the network element Z is specially: network element A-network element 2-network element 9-network element 16-network element 17-network element Z.
Step 106:NMS is with between the teleservice two-end-point network element that calculates, in the minimum weights route of NMS layer, the part route (SNC) that is under the jurisdiction of each EMS is handed down to corresponding EMS respectively, each EMS is parallel to carry out the establishment of teleservice route according to the part route of described minimum weights route in self, the detailed routing iinformation of teleservice in self of creating preserved, and returned the establishing route results messages to NMS.
This establishing route results messages is used for whether creating success by EMS to the part route of NMS notice EMS inside.
For example, NMS sends to EMS under the network element A with the part route network element A-network element 2 in the minimum weights route of NMS layer, part route network element 9-network element 16 is sent to network element 9 and network element 16 affiliated EMS, part route network element 17-network element Z is sent to EMS under the network element Z, afterwards, three minimum weights routes of described part establishing route EMS layer that EMS issues according to NMS, each EMS preserves the detailed routing iinformation of the minimum weights route of EMS layer of the described part route correspondence of creating, and basic routing iinformation is reported NMS.
Step 107:NMS receives the establishing route results messages that each EMS returns, and the minimum weights route between the described teleservice two-end-point network element that calculates in the step 105 integrates, and stores as the establishment result of this teleservice.
Wherein, to be generally the state that identifies the part route of each EMS inside respectively according to the establishing route result be available or unavailable in described integration.
Wherein, EMS can be with the routing iinformation of the teleservice of the inner required foundation of the form of database storage self.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
