[0049] To further illustrate the technical solution provided by the embodiments of the present application, a detailed description is given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The existing optical transmission network basically includes OTN networking and PON networking. For the configuration of optical P2MP services, it is necessary to configure the OTN equipment in the OTN networking used to transmit the optical P2MP services and the P2MP equipment in the PON networking used to implement the optical P2MP services at the same time. In the configuration method of the prior art, because it is usually impossible to query the link status of the OTN equipment and the P2MP equipment, the configuration of the two usually requires manual switching of the topology layer through the network element management system multiple times to configure the OTN networking and the PON networking respectively, and it is impossible to configure the devices in the two networks at the same time. At present, the internal network deployment of commercial buildings is costly and complex, and the manual configuration process of the optical P2MP service is cumbersome, resulting in the problem of easy errors and low efficiency in the configuration of the optical P2MP service.

[0051] In view of the fact that the above-mentioned manual configuration process of the optical P2MP service is cumbersome, which leads to the problem of easy errors and low efficiency when configuring the optical P2MP service, the embodiment of the present application proposes a configuration method for the optical P2MP service, which can integrate the configuration process of the optical P2MP service and the OTN technology to achieve top-down unification, so as to improve configuration efficiency and management convenience.

[0052] A configuration method for an optical P2MP service in an embodiment of the present application is as follows: Figure 1 As shown, including:

[0053] Step 101: Acquire source node, sink node and configuration reference information of an optical P2MP service.

[0054] Step 102, based on the pre-stored topology of the optical transmission network OTN and the link relationship between the OTN device in the OTN and the P2MP device in the passive optical network PON, query the available route from the source node to the sink node.

[0055] By pre-storing the topology of the optical transmission network OTN and the link relationship between the OTN equipment in the OTN and the P2MP equipment in the passive optical network PON, the network management equipment can query the nodes in the OTN and PON at the same time without switching the topology layer, which improves the configuration speed of the optical P2MP service and is less prone to errors.

[0056] Step 103: Select one of the available routes as the target route, and generate time slot configuration information configured for different nodes on the target route.

[0057] In the embodiment of the present application, the time slot configuration information is reasonably and automatically configured by the network management device according to the information of the target route. In actual use, the corresponding time slot configuration information can also be generated according to the operation instructions of the interface.

[0058] Step 104: Generate and issue optical P2MP service configuration information for each node on the target route based on the configuration reference information and the time slot configuration information, wherein the optical P2MP service configuration information includes first configuration information configured for each node device in the OTN and second configuration information configured for each node device in the PON.

[0059] Through the configuration method of an optical P2MP service in the above-mentioned embodiment of the present application, it is only necessary to obtain the core information of the service, that is, the source node, the sink node and the configuration reference information, to quickly and efficiently complete the distribution and configuration of the service, and can integrate the configuration process of the optical P2MP service and the OTN technology to achieve top-down unification, so as to improve configuration efficiency and management convenience.

[0060] Specifically, when the gateway device responds to the operation of creating a P2MP service, after obtaining the source node and the sink node input by the user, Figure 2 As shown, it also includes:

[0061] Step 201, in response to a node pool determination instruction, determining a first CTP node pool pre-created under a first device where the source node is located, and a second CTP node pool pre-created under a second device where the sink node is located;

[0062] Step 202: Select a corresponding source CTP node from the available CTP nodes in the first CTP node pool;

[0063] Step 203: Select a corresponding sink CTP node from the available CTP nodes in the second CTP node pool.

[0064] In an embodiment of the present application, the first CTP node pool and the second CTP node pool can be displayed through an interface, including the services that have been established in the corresponding source and sink nodes and the CTP node status of the selected source and sink nodes, and the corresponding source CTP node and sink CTP node are selected based on the operations on the interface.

[0065] In some possible embodiments, the network management device first obtains a pre-created CTP node pool from a background database, and the CTP node pool is pre-created through the following steps: Figure 3 As shown, including:

[0066] Step 301, determining the maximum number of CTP nodes that a device can support, wherein the device includes an OTN device and a P2MP device;

[0067] Step 302, traverse the services configured for each device, create a CTP node pool including multiple CTP nodes for each device based on the maximum number of CTP nodes, and store node information and service information of each CTP node.

[0068] The network management device traverses the OTN board and the P2MP device, pre-creates CTP nodes according to the service types supported by the OTN board and the P2MP device and the maximum capabilities of the OTN board and the P2MP device, and records the node information and service information of the pre-created CTP node in the CTP node pool.

[0069] In some possible embodiments, the node information includes at least one of the following: attribute information, state information, and a mapping relationship and mapping type with an element management system EMS (element management system) of the CTP node;

[0070] The service information includes at least one of the following: service name, occupied time slot, and service type.

[0071] The above-mentioned network element management system is a system for managing one or more telecommunication NEs (Network Elements) of a specific type. Generally speaking, EMS manages the function and capacity of each NE, but does not care about the communication between different NEs in the network.

[0072] In the embodiment of the present application, the node information and service information of the CTP node in the CTP node pool in the background database can ensure the real-time performance of the service, and the node pool is a pre-created CTP node, that is, the CTP node will not change with the addition or deletion of the service, but is naturally generated according to the characteristics of the device, and is used for information query and associated display of the CTP node in the service layer and routing, and its display interface is as follows: Figure 4 shown.

[0073] In some possible embodiments, in response to the node pool determination instruction, a first CTP node pool pre-created under the first device where the source node is located and a second CTP node pool pre-created under the second device where the sink node is located are determined, such as Figure 5 As shown, it also includes:

[0074] Step 501: when there is no available CTP node in the first CTP node pool / the second CTP node pool, corresponding prompt information is displayed on the interface;

[0075] Step 502, determine the updated source node / destination node based on the modification operation on the source node / destination node, and trigger the node pool determination instruction.

[0076] After the corresponding source and sink CTP nodes are determined through the above process, the gateway device queries the available routes from the source node to the sink node based on the pre-stored OTN topology and the link relationship between the OTN device in the OTN and the P2MP device in the passive optical network PON.

[0077] Specifically, firstly, all available routes in the OTN and PON are queried, without limiting the source node and the sink node, such as Figure 6 As shown, including:

[0078] Step 601, first query all links in the background database and cache them locally, wherein the links include physical links and OTN links.

[0079] In the embodiment of the present application, the link does not include a P2MP device, and there is no need to cache the connection relationship between the P2MP device and the OTN device. The link of the device where the optical P2MP service is located, the connection relationship between the device where the P2MP service is located and the OTN device, because of the topological layering problem, there will be a logical link of a splitter in the middle, connecting the P2MP device and the OTN device. The actual link relationship between the P2MP device and the OTN device will be stored in the corresponding field of the network element table of the background database, rather than in the link. This standardizes the query logic of the link, can effectively reduce the amount of logical calculation, and speed up the query efficiency.

[0080] Step 602: Get the source and sink nodes from the cached link, where the source and sink nodes are all OTN devices in the OTN. The link does not contain P2MP devices (logical link devices), which can reduce the amount of logical calculation and improve query efficiency.

[0081] Step 603: After obtaining all source and sink nodes, that is, all OTN devices, route calculation is performed to obtain all routes.

[0082] For example, there is a link A from device A to device B, and a link B from device B to device C. The destination node of link A is used as a criterion to determine whether there are other links with this destination node as the source node. If so, they are concatenated into a route from device A to device B and then to device C, with the source node being device A and the destination node being device C. A recursive query is performed on the set of links to splice out all routes.

[0083] Step 604: Based on the nodes in all routes, an optical P2MP service query is performed in the background database, and a P2MP device is extended on the corresponding node involving the optical P2MP service.

[0084] Find out whether the nodes in all the routes have corresponding optical P2MP services and OTN services. If there is no P2MP service, the nodes in the route remain unchanged, and it is a pure OTN device service. If the optical P2MP service is found, the corresponding P2MP device is extended at the corresponding node of the route according to the information of the optical P2MP service. After completing the query of all nodes, all available routes in the OTN and PON are queried.

[0085] In some possible embodiments, all service paths and corresponding routes in the OTN and PON can be fully displayed. Based on all routes, a route list is formed, and the route list can be one route or multiple routes. The gateway device can automatically recommend an adapted route according to different types of services created and display it visually.

[0086] In the embodiment of the present application, after the gateway device has queried all routes, based on the source node and the sink node of the optical P2MP service, an available route from the source node to the sink node is queried.

[0087] In some possible embodiments, after the network management device obtains a route list of all available routes from the source node to the sink node, it marks the shortest route. For example, there may be three routes from device A to device C: from device A to device B and then to device C, from device A to device B1 to device B2 and then to device C, and from device A to device B1 to device B and then to device C. However, the route from device A to device B and then to device C is the shortest route, so the route is marked and all available routes are displayed on the interface, such as Figure 7 shown.

[0088] In some possible embodiments, after querying the available routes from the source node to the sink node, the gateway device further includes:

[0089] Displaying the queried available routes from the source node to the sink node on the interface;

[0090] The selecting one of the available routes as the target route comprises:

[0091] According to the selection operation of the available routes displayed on the interface, the selected available route is used as the target route.

[0092] In an embodiment of the present application, the user can select the above-mentioned shortest route as the target route based on the recommendation, or select different route constraint strategies according to different actual business situations to configure special scenario services. The gateway device does not force the shortest route to be automatically issued, which facilitates users to freely network.

[0093] In some possible embodiments, after the target route is selected, time slot configuration information configured for different nodes on the target route is generated to comply with network planning. The time slot configuration information can also be generated according to user operations on the interface, and is not limited to the automatic generation method of the gateway device.

[0094] After determining the above-mentioned time slot configuration information, based on the configuration reference information, the gateway device generates optical P2MP service configuration information for each node on the target route, and the optical P2MP service configuration information includes first configuration information configured for the node device in the OTN and second configuration information configured for the node device in the PON.

[0095] In some possible embodiments, the configuration reference information includes at least one of the following:

[0096] The transmission rate of the optical P2MP service, the cross-connection mode of the OTN equipment in the transmission path, the time slot configuration information, and the OTN protection mode.

[0097] In the embodiment of the present application, the configuration reference information can be obtained according to the input instructions of the user when actually configuring the service, or the network management device can perform reasonable automatic configuration according to the information of the optical P2MP service and the target route. The embodiment of the present application only provides an exemplary implementation method, and does not specifically limit the source of the configuration reference information.

[0098] In some possible embodiments, the first configuration information configured for the node device in the OTN includes at least one of the following: attribute information, status information, cross-connection mode of the OTN device, time slot configuration information and OTN protection mode of the CTP node; the second configuration information configured for the node device in the PON includes at least one of the following: attribute information, status information of the CTP node, and the transmission rate of the optical P2MP service.

[0099] In some possible embodiments, the generated service configuration information further includes: a source node, a sink node, a routing list, and operation type information, and the operation type information includes at least one of the following: create, delete, modify, and query.

[0100] In the embodiment of the present application, after the service configuration information is generated, the network management device queries the corresponding CTP node information in the CTP node pool according to the attribute information of the CTP node in the service configuration information, and obtains the mapping relationship and mapping type between the CTP node and the network element management system EMS. According to the queried EMS system mapping relationship and mapping type, the attribute information and status information of the CTP node in the service configuration information are converted according to the data type of the corresponding EMS system, and the configuration conversion information of the CTP node is generated.

[0101] Taking the creation of optical P2MP services as an example, the command scheduler of the cross-process method such as the interface calls the optical P2MP service creation interface of the EMS system itself, and the parameters of the creation interface are transmitted according to the configuration conversion information of the above CTP node. The corresponding EMS system forwards the configuration conversion information to the OTN device / optical P2MP device of the corresponding node, and each device configures the service based on its own configuration conversion information.

[0102] In some possible embodiments, the result of the service operation is fed back to the gateway device. Taking the creation of the optical P2MP service as an example, when the creation succeeds or fails, there are two ways to notify the network management device whether the optical P2MP service is created, including:

[0103] Method 1: After the EMS system completes the processing, it sends the processing result, and the command scheduler receives the processing result and displays it on the interface of the network management device.

[0104] Method 2: After obtaining the processing results of all EMS systems through the command scheduler, all received processing results are displayed on the interface of the network management device.

[0105] In some possible embodiments, the network management device updates the CTP node information included in the corresponding service in the CTP node pool in the background database according to the received service processing result.

[0106] Through the configuration method of an optical P2MP service described in the embodiment of the present application, not only can the optical P2MP service be configured, but also the configuration of a simple OTN service can be configured using the method in the embodiment of the present application. Wherein, because the types of services are different, the service configuration information only includes the first configuration information configured for each node device in the OTN, and the remaining method steps are also applicable when creating an OTN service.

[0107] The following is a configuration process of an optical P2MP service based on the above embodiment of the present application. Figure 8 As shown, including:

[0108] Step 801, obtaining a source node A, a sink node B and configuration reference information of an optical P2MP service, wherein the configuration reference information includes a transmission rate and an OTN protection mode of the optical P2MP service;

[0109] Step 802, based on the pre-stored topology of the optical transmission network OTN and the link relationship between the OTN device in the OTN and the P2MP device in the passive optical network PON, query all available routes in the OTN and the PON;

[0110] Step 803: Based on the source node and the sink node of the optical P2MP service, available routes link1, link2, link3 and link4 from the source node A to the sink node B are queried, the shortest route link1 is marked and all available routes are displayed on the interface;

[0111] Step 804, according to the selection operation of the available routes displayed on the interface, select the available route link1 as the target route, and generate time slot configuration information configured for different nodes on the target route link1;

[0112] Step 805: Based on the configuration reference information and the time slot configuration information, generate first configuration information configured for each node device in link1 belonging to the OTN, and second configuration information configured for each node device in link1 belonging to the PON.

[0113] Step 806: According to the attribute information of the CTP node in the service configuration information, the mapping relationship and mapping type between the CTP node and the element management system EMS are obtained, the first configuration information and the second configuration information are converted into first configuration conversion information and second configuration conversion information, and sent to the corresponding EMS system to configure each node on the target route link1.

[0114] Through the configuration method of an optical P2MP service proposed in the above embodiment of the present application, only the core information of the service, namely the source node, the sink node and the configuration reference information, needs to be obtained to quickly and efficiently complete the distribution and configuration of the service, thereby improving the efficiency and accuracy of service configuration. When it is necessary to establish an optical P2MP service, the OTN link between the source node and the destination node of the optical P2MP service is automatically configured as an OTN cross-connection, and the two networks of OTN and PON are automatically configured at the same time, integrating the configuration process of the optical P2MP service and the OTN technology, achieving top-down unification, so as to improve configuration efficiency and management convenience.

[0115] Based on the same inventive concept, the embodiment of the present application also proposes a configuration device for an optical P2MP service, such as Fig. 9 As shown, including:

[0116] The information acquisition module 901 is used to acquire the source node, sink node and configuration reference information of the optical P2MP service;

[0117] The route query module 902 is used to query the available route from the source node to the destination node based on the pre-stored topology of the optical transmission network OTN and the link relationship between the OTN device in the OTN and the P2MP device in the passive optical network PON;

[0118] The time slot configuration module 903 is used to select one of the available routes as the target route and generate time slot configuration information configured for different nodes on the target route;

[0119] The configuration module 904 is used to generate and issue optical P2MP service configuration information of each node on the target route based on the configuration reference information and the time slot configuration information, wherein the optical P2MP service configuration information includes first configuration information configured for the node device in the OTN and second configuration information configured for the node device in the PON.

[0120] Through the configuration device of an optical P2MP service in the above-mentioned embodiment of the present application, the configuration process involved in the optical P2MP service is automated, and the configuration process of the optical P2MP service and the OTN technology can be integrated to achieve top-down unification, thereby improving the configuration efficiency, accuracy and convenience. By introducing a new configuration module, the seamless connection between the optical P2MP service and the OTN technology is achieved, and the configuration efficiency and management convenience are improved. The method is applicable to the configuration and management of the optical P2MP service and the OTN technology in the optical transmission network, and has broad application prospects.
