Method 3: Choose one of the shortest business paths.

In this embodiment, a third mode is selected, and one of the shortest service paths is selected, and the subject performing the operation may be a user or a system. The shortest service path represents the shortest distance from the client layer service start information to the termination information. The shortest service path includes, but is not limited to, the number of channels through which the service path passes and the service channel endpoint, which is referred to as a service endpoint. In this embodiment, the shortest service path is preferred, and the service created according to the shortest service path is more resource-saving during use.

In this embodiment, the created client layer service and the corresponding service layer service include the client layer service and the service layer service. Service layer services and services required by the customer layer business At least one of the service layer services required by the layer service, where the corresponding service layer service includes a service layer service required by the client layer service and a service layer service required by the service layer service.

In this embodiment, since there is no hierarchical relationship between the client layer service and the service layer service in the selected shortest service path, only a service path from the start information of the client layer service to the termination information is used, in order to create a hierarchy between services. The process of creating a client layer service and/or a corresponding service layer service according to the selected shortest path includes: obtaining information of all nodes through which the shortest service path passes, the node including the service channel endpoint, and creating a client layer according to the information of the node Business and corresponding service layer business.

Preferably, the node information further includes information that is multiplexed or demultiplexed between adjacent nodes; the neighboring node includes two nodes that can be multiplexed or demultiplexed with each other. In this embodiment, The information that is multiplexed or demultiplexed between neighboring nodes includes the number of times of multiplexing or demultiplexing between adjacent nodes or the number of neighboring nodes where multiplexing or demultiplexing occurs, as long as the node or The information obtained by the neighboring nodes to achieve the same functions as the present application belongs to the scope of protection claimed in this embodiment. Preferably, when a node is multiplexed once, the system count is incremented once, and when a node is demultiplexed once, the count is decreased once.

In this embodiment, the client layer service node to the service layer service node or the service layer service node to the required service layer service node is once multiplexed for the node, and the service layer service node is connected to the client layer service node or the service layer service node. The service layer service node to the service layer service node is demultiplexed once for the node; when the node is multiplexed to the service layer service node or the node is demultiplexed to the client layer service node or the service layer service required service layer service node is solved When the service layer service node is used, the node is said to be adjacent to the other node to be multiplexed or demultiplexed.

In this embodiment, the definition of the node is extended, and the node is no longer the existing network element node, but further includes the service end point. At the same time, the meaning of the adjacent node is also extended in this embodiment, and the adjacent node is not only The endpoints of the two sides of the existing service are further multiplexed from the client layer service endpoint to the service layer service endpoint, or the service layer service endpoint is demultiplexed to the client layer service endpoint, for example, as shown in FIG. When traversing from the starting point A to the ending point Z, The nodes that have passed have endpoints 2, 3, 4, 5, · '11; the neighboring nodes they pass through have Endpoint 2 and Endpoint 3, Endpoint 3 and Endpoint 4, Endpoint 5 and Endpoint 6, Endpoint 6 and Endpoint 7, Endpoints 7 and Endpoint 8, Endpoint 9 and Endpoint 10, Endpoint 10 and Endpoint 11. That is to say, these endpoints are also used as neighboring nodes of the service side, thus expanding the range of adjacent nodes, and facilitating the system to quickly create the client layer service and the corresponding service layer service according to the service information.

Preferably, the client layer service and/or the corresponding service layer service process are created according to the information of the node, including:

Determining the client layer service and the corresponding service layer service according to the start information and the termination information; determining the hierarchical relationship between the client layer service and the service layer service according to the information of multiplexing or demultiplexing between adjacent nodes, and according to the hierarchy The relationship between the neighboring nodes in the present embodiment is the number of times of multiplexing or demultiplexing between neighboring nodes.

In this embodiment, the client layer service and the corresponding service layer service are preferably created by means of node traversal. The node traversal method first determines that there is a client layer service and a service layer service in the service path according to the start information and the termination information of the client layer service, and only the client layer service can be determined in the service path, but the client There is no hierarchical relationship between the layer service and the corresponding service layer service. It is not known that the service layer service required by the client layer service and the service layer service required by the service layer service belong to the first service level. In this embodiment, it is preferable to determine the service hierarchy relationship by the number of times the neighboring node performs multiplexing or demultiplexing, starting from the starting point of the client layer service, and when the node is once multiplexed, the client layer service is indicated. The node to which the starting point is multiplexed is its service layer service node. If no multiplexing or demultiplexing occurs, the node is a peer service node, and so on, until the termination point of the client layer service, so that The service layer service required by the client layer service, the service layer service, the client layer service, and the service layer service required by the service layer service are determined, thereby creating a business hierarchy relationship.

In this embodiment, how to create a client layer service and/or a corresponding service layer service by traversing is specifically introduced. Referring to FIG. 2, for better description, the endpoints 3 and 4 are selected in this embodiment. The channel is defined as the first channel, the channel where the endpoints 5 and 8 are located is defined as the second channel, the channel where the endpoints 6, 7 are located is defined as the third channel, and the channel where the endpoints 9, 10 are located is defined as the fourth channel, where the endpoint A- 2 and the channel where the endpoint 11-Z is located is set as the client layer service channel, and the first channel, the second channel, the third channel, and the fourth channel are service layer service channels respectively, and the first channel, the second channel, and the fourth channel are the same The channel of the diameter is defined as the channel of the same layer. When traversing from A to Z, the nodes that pass through include: 2, 3, 4, 5, - - - 11; the adjacent nodes passing through include: 2 and 3, 3 and 4, 5 and 6, 6 and 7, 7 and 8, 9 and 10, 10 and 11, during the traversal process, the system records each passing node (also the channel end point), and the system Record the number of times each node is multiplexed or demultiplexed. The system records the passing nodes through naming, measuring the length of the path, and measuring the bandwidth. Of course, it is not limited to the above. Type, in the present embodiment, preferably preclude be recorded by the node after naming the channel number and node number in combination. Each time a node passes, the channel number of the node and the corresponding node number are recorded, and then the position of the next adjacent node of the current node is determined. If it is necessary to perform multiplexing once and then reach the next adjacent node, the count is incremented by one. Bit, if a demultiplexing is required to reach the next adjacent node, the count is reduced by one bit, and traversed in this way, for example, node 5, where node 5 is named 2.1 (2 represents the second channel) , 1 represents the first endpoint of the second channel. After recording the naming of the node 5, the neighboring node of the node 5 is judged again. At this time, the neighboring node of the node 5 is the node 6, and the node 5 is the node. 6 needs to occur once for multiplexing, then the count is increased by one. In Fig. 2 of the present embodiment, two times of multiplexing and two times of demultiplexing need to be performed separately to complete the traversal of the entire process.

In the process of completing the entire traversal, according to the starting point A and the ending point Z of the customer layer service, it can be determined that the service corresponding to the node connected to the starting point A and the ending point Z is the customer layer service, that is, the customer layer service A- 2-11-Z; wherein, the first multiplexing occurs when the slave node 2 enters the node 3, the number is incremented by one, and the node 3 is determined to be the service layer service. According to the node naming, the node 3 is named 1.1. The name of node 4 is 1.2, so that it can be determined that node 3 and node 4 belong to the same channel, that is, node 4 also belongs to the service layer service node. In this embodiment, the node The naming rules are as follows: Node 4 is named 1.2, where 1 indicates that the channel number is 1; 2 indicates the second endpoint of the first channel. The system further determines that no demultiplexing occurs between the node 4 and the node 5, and it is determined that the node 4 and the node 5 belong to the service layer service of the same level, and it is determined that the node 5 to the node 6 need to occur for the second time. Reuse, increase the number by one, and determine that the service layer service where the node 6 is located is the service layer service of the service layer service where the node 5 is located, and again according to the node naming, the node 7 that belongs to the same channel as the node 6 can be determined. It is judged again that the node 7 needs to be demultiplexed to the node 8 once, and the count is reduced by one bit. When the count is decreased by one bit, it is judged that the node 8 and the node 5 belong to the same level of the service layer service, and the node 8 to the node 9 determine the manner and the node. 4 to node 5 are the same, node 9 to node 10 are judged in the same manner as node 3 to node 4, and node 10 to node 11 are judged in the same manner as node 7 to node 8, so that the client layer service A-2 is finally determined. In addition to -11-Z, there are service layer services 3-4-5-8-9-10; and service layer services required for service layer services 6-7.

At the same time, the meaning of the adjacent node is also extended in this embodiment, and the adjacent node is not only And then the endpoints of the two sides of the existing service, but further include multiplexing from the client layer service endpoint to the service layer service endpoint, or the service layer service endpoint demultiplexing to the client layer service endpoint, that is, the endpoints are also As a neighboring node of the service side, the range of adjacent nodes is expanded, and the system can quickly create a client layer and a corresponding service layer according to service information.

Preferably, the processor 402 creates a client layer service and/or a corresponding service layer service process according to the information of the node, including:

Determining the client layer service and the corresponding service layer service according to the start information and the termination information; determining the hierarchical relationship between the client layer service and the service layer service according to the information of multiplexing or demultiplexing between adjacent nodes, and according to the hierarchy The relationship between the neighboring nodes in the present embodiment is multiplexed or demultiplexed between the neighboring nodes. The number of times of demultiplexing.

In this embodiment, the client layer service and the corresponding service layer service are preferably created by means of node traversal. The node traversal method first determines that there is a client layer service and a service layer service in the service path according to the start information and the termination information of the client layer service, and only the client layer service can be determined in the service path, but the client There is no hierarchical relationship between the layer service and the corresponding service layer service. It is not known which service level the service layer service required by the client layer service and the service layer service required by the service layer service belong to. In this embodiment, it is preferable to determine the service hierarchy relationship by the number of times the neighboring node performs multiplexing or demultiplexing, starting from the starting point of the client layer service, and when the node is once multiplexed, the client layer service is indicated. The node to which the starting point is multiplexed is its service layer service node. If no multiplexing or demultiplexing occurs, the node is a peer service node, and so on, until the termination point of the client layer service, so that The service layer service required by the client layer service, the service layer service, the client layer service, and the service layer service required by the service layer service are determined, thereby creating a business hierarchy relationship.

Preferably, the processor 402 obtains all possible service paths according to the service information, where the service information further includes condition constraint information, and the system creates the client layer service and service according to the start information and the termination information of the client layer service, and the condition constraint information. Layer service, the condition constraint information is added to be more ready to create a service required by the user, and the condition constraint information includes information that the signal must pass and/or prohibit, and the condition constraint information includes but is not limited to any one of the following : Service layer endpoints, ports, boards, NEs, and service layer services. Embodiment 4:

In order to further explain the above service creation, FIG. 5 is a method for creating a WDM GE layer service provided by the example.

The service layer of the GE layer service is the ODU service, the service layer of the ODU layer service is the OCH service, and the service layer of the OCH layer service is the OMS service. In the normal creation, the service layer service of each layer needs to be created first, and then the required GE layer service is created. In this embodiment, the application is used. Applying the method in the first embodiment to create a GE layer service, where the method includes: Step 501: Setting basic data including a service start endpoint and a terminating endpoint;

Step 502: Obtain calculation data.

Step 503: Create a service route.

Step 504: Determine whether the created service route is suitable. If yes, go to step 505. If no, go to step 501;

Step 505: The device is delivered to the device to enable the created service route.

In step 501, in addition to the starting and ending endpoints of the service, the created hierarchical GE may be set. Before the service is created, the service level GE to be created and the starting point and the ending point of the service need to be planned in advance. There may be more than one starting point for this business;

In step 501, in order to make the service more suitable for the user's needs, the constraint information may be set, and the constraint information is generally divided into information that must be passed and/or prohibited.

In this embodiment, the GE layer service is created, and the ODU layer service can be skipped and bound to the OCH layer service. In addition, the port constraint can be restricted to the port of the OMS layer service, that is, the service passes or is not allowed to pass the service. The port.

In step 502, the calculation data is obtained. The step is that the network management system reads the data required for calculating the service route from the database, for example, reading the service layer service path from the service table. After the above data is set, the route calculation is started. When calculating the route, it is considered that the endpoint is not only the endpoint of the GE layer service in each network element, but also the endpoints of the ODU, OCH, and other layer services. These endpoints are also considered as neighbors of the service side and are added to the routing algorithm. In this way, the scope of the calculation is expanded, and all levels are included, so that all service layer services and service layer services of the service layer service can be calculated.

In step 503, a service route is created. In this step, the GE layer service is calculated, and six routes of ODU1, ODU2, ODU3, OCH1, OCH2, and OCH3 are obtained. First, it is found that ODU3 has passed the service starting point A, and ODU1 has passed the service termination point. Then, the entire path can be connected: ODU3--- ODU1, there is no connected path after the connection Clear customer layer business and service layer business hierarchy, therefore, it is necessary to traverse all routes and establish hierarchical relationships. It is found that ODU2 belongs to the same layer of service-customer layer service as ODU3 and ODU1, and further discovers that the service layer service of 0DU3 is 0CH3, the service layer service of 0DU2 is 0CH2, and the service layer service of 0DU1 is 0CH1, therefore, the path is clear. ODU3,

The hierarchical relationship between the six routes ODU2, ODU1, OCH1, OCH2, and OCH3.

After the route is created, in this embodiment, the user is displayed to the user through the user interaction interface. In this embodiment, the route display manner has at least the following three modes:

The first type: display through the connection of the topology;

The second type: by means of text (such as a table);

The third type: a combination of tree expansion and topology expansion;

After being displayed to the user in the above manner, if the user is satisfied, the process proceeds to step 505. If not, the process returns to step 501 to re-create the route.

Step 505 is sent to the device to enable the created service route.

After the user obtains the route that he wants, the device can be delivered to the device. The device is a network element device and creates a real service route on the device.
