[0073] When the service routing is asymmetric routing, the client service type is added to the mapping of the corresponding ODUk port, and the service download paths of different services are obtained according to the client service type.

[0074] The device of the present invention calls the P+O asymmetric service management program stored in the memory 1005 through the processor 1001, and further performs the following operations:

[0075] Layering services at both ends of the P+O asymmetric service into ODUk / OTUk / OCH according to the service download path;

[0076] Relevant overhead is added to the CLIENT service data at the ODUk layer, and resource configuration management is performed on each layer of the P+O asymmetric service.

[0077] Through the above scheme, this embodiment obtains the extended interface parameters of the OTN service, creates a P+O asymmetric service according to the extended interface parameters; performs pathfinding processing on the P+O asymmetric service to obtain a service download path; and performs hierarchical resource configuration management on the P+O asymmetric service according to the service download path, so as to directly create an asymmetric service of the Ethernet scenario on the OTN, improve configuration efficiency, realize lossless adjustment of the OTN asymmetric service bandwidth, adapt to the changing requirements of asymmetric service traffic, and improve the speed and efficiency of P+O asymmetric service management.

[0078] Based on the above hardware structure, an embodiment of the P+O asymmetric service management method of the present invention is proposed.

[0079] Reference Figure 2 , Figure 2 It is a flowchart of the first embodiment of the P+O asymmetric service management method of the present invention.

[0080] In a first embodiment, the P+O asymmetric service management method comprises the following steps:

[0081] Step S10: Acquire extended interface parameters of the OTN service, and create a P+O asymmetric service according to the extended interface parameters.

[0082] It should be noted that in the asymmetric model, different service models can be distinguished by correspondingly extending the extended interface parameters of the relevant interfaces of the OTN service, thereby creating a P+O asymmetric service, that is, a packet transport network + optical transport network (Packet Transport Network + Optical Transport Network, P+O) asymmetric service.

[0083] In the specific implementation, the P+O application scenario is that when the signal transmission encapsulation on the signal and receiving sides is different, one side is P and the other side is O, the network can be jointly networked, and the packet transmission network and the optical transmission network can be directly connected for signal conversion.

[0084] Step S20: performing path finding processing on the P+O asymmetric service to obtain a service download path.

[0085] It can be understood that by performing path finding processing on the P+O asymmetric service, service download paths of different services in the P+O asymmetric service can be obtained.

[0086] Step S30: performing hierarchical resource configuration management on the P+O asymmetric service according to the service download path.

[0087] It should be understood that the service download path can download relevant data overheads for different types of services in the P+O asymmetric service. Generally, the P+O asymmetric service is first layered and the configuration management of relevant resources is performed on the layered service.

[0088] Through the above scheme, this embodiment obtains the extended interface parameters of the OTN service, creates a P+O asymmetric service according to the extended interface parameters; performs pathfinding processing on the P+O asymmetric service to obtain a service download path; and performs hierarchical resource configuration management on the P+O asymmetric service according to the service download path, so as to directly create an asymmetric service of the Ethernet scenario on the OTN, improve configuration efficiency, realize lossless adjustment of the OTN asymmetric service bandwidth, adapt to the changing requirements of asymmetric service traffic, and improve the speed and efficiency of P+O asymmetric service management.

[0089] Further, Figure 3 FIG. 1 is a flow chart of a second embodiment of the P+O asymmetric service management method of the present invention. Figure 3 As shown, a second embodiment of the P+O asymmetric service management method of the present invention is proposed based on the first embodiment. In this embodiment, step S10 specifically includes the following steps:

[0090] Step S11: Obtain extended interface parameters of the OTN service, determine whether the current service is an asymmetric service according to the extended interface parameters, and obtain a determination result.

[0091] It should be noted that in the asymmetric model, different service models can be distinguished by correspondingly extending the extended interface parameters of the relevant interfaces of the OTN service, that is, judging whether the current service is an asymmetric service according to the extended interface parameters, thereby obtaining corresponding judgment result information.

[0092] Step S12: Create a P+O asymmetric service according to the judgment result.

[0093] It can be understood that different creation strategies can be adopted to create the P+O asymmetric service according to different judgment results.

[0094] This embodiment uses the above scheme to obtain the extended interface parameters of the OTN service, determine whether the current service is an asymmetric service according to the extended interface parameters, and obtain a determination result; create a P+O asymmetric service according to the determination result, and directly create an asymmetric service for an Ethernet scenario on the OTN, thereby improving configuration efficiency.

[0095] Further, Figure 4 FIG. 4 is a flow chart of a third embodiment of the P+O asymmetric service management method of the present invention. Figure 4 As shown, a third embodiment of the P+O asymmetric service management method of the present invention is proposed based on the second embodiment. In this embodiment, the step S12 specifically includes the following steps:

[0096] Step S121: When the judgment result is that the current service is the asymmetric service, the Ethernet signal is processed and encapsulated and mapped, and the client service type is added to the mapping.

[0097] It should be noted that when the judgment result is that the current service is the asymmetric service, the Ethernet signal can be encapsulated and mapped after being processed by OTN+Packet Transport Network (PTN) networking, and the client service type can be added during the mapping process.

[0098] Step S122: Create a P+O asymmetric service according to the mapped Ethernet signal and a preset EOO model.

[0099] It is understandable that after the mapping is completed, the mapped Ethernet signal can be combined with a preset Ethernet over OTN (EOO) model to create a P+O asymmetric service according to the preset EOO model.

[0100] Furthermore, the step S122 specifically includes the following steps:

[0101] Generate service creation information according to the mapped Ethernet signal and the preset EOO model;

[0102] A P+O asymmetric service is created according to the service creation information, one end of the P+O asymmetric service is set to O mode, the service type is marked as asymmetric, and the other end of the P+O asymmetric service is selected to be set to P mode.

[0103] It should be noted that when creating a P+O asymmetric service, you can select O mode at one end and P mode at the other end. The O mode marks the service type as asymmetric. Generally, the O end and the P end build optical channel data unit (ODUk) / optical channel transport unit (OTUk) / optical channel (OCH) services according to the service layer.

[0104] In the specific implementation, in the P mode, the service signal is encapsulated and transmitted according to the packet transport network PTN, which has L2 virtual private network (VPN) and other signals; in the O mode, the service signal is encapsulated and transmitted according to the optical transport network OTN.

[0105] Step S123: When the judgment result is that the current service is a symmetric service, a P+O asymmetric service is created according to a preset symmetric model process.

[0106] It should be understood that when the judgment result is that the current service is a symmetric service, a P+O asymmetric service may be created according to a preset symmetric model process.

[0107] In a specific implementation, by judging whether the current service is the asymmetric service, the Client service type is added to the mapping. If it is not an asymmetric service, the service creation can be performed according to the pre-set normal process.

[0108] Through the above scheme, this embodiment processes the Ethernet signal and then encapsulates and maps it when the judgment result is that the current service is the asymmetric service, and adds the client service type in the mapping; creates a P+O asymmetric service according to the mapped Ethernet signal in combination with a preset EOO model; creates a P+O asymmetric service according to a preset symmetric model process when the judgment result is that the current service is a symmetric service; can directly create an asymmetric service for an Ethernet scenario on an OTN by determining different models according to the service type, thereby improving configuration efficiency and reducing the time consumed in P+O asymmetric service management.

[0109] Further, Figure 5 FIG. 4 is a flow chart of a fourth embodiment of the P+O asymmetric service management method of the present invention. Figure 5 As shown, a fourth embodiment of the P+O asymmetric service management method of the present invention is proposed based on the first embodiment. In this embodiment, step S20 specifically includes the following steps:

[0110] Step S21: Check the service route crossing situation of the P+O asymmetric service according to the sink mapping mode.

[0111] It should be noted that the service routes of the P+O asymmetric service can be checked whether they intersect according to the sink mapping mode, that is, the intersection of the service routes can be checked after the path finding starts. Generally, the sink mapping mode of the sink can be used to analyze whether the service routes intersect.

[0112] In actual operation, in an asymmetric model, the network element at one end of the O mode needs to check the cross-connection, while the one at the P mode does not. By setting parameters, you can determine the port input and output status of each network element and whether the cross-connection needs to be checked.

[0113] Step S22: When the route crossing condition is crossing completed, set the service route.

[0114] It should be understood that when the routing intersection situation is a crossing completion, that is, when the crossing rule is completed, the path finding process ends and the corresponding service route can be set.

[0115] Step S23: Obtain a service download path according to the service route.

[0116] It is understandable that the service download path of the data resource of the related service can be obtained through the service routing.

[0117] Through the above scheme, this embodiment checks the service route crossing situation of the P+O asymmetric service according to the sink mapping mode; sets the service route when the route crossing situation is completed; obtains the service download path according to the service route, and can directly create an asymmetric service for the Ethernet scenario on the OTN, thereby improving the configuration efficiency and the speed and efficiency of the P+O asymmetric service management.

[0118] Further, Figure 6 FIG. 5 is a flow chart of a fifth embodiment of a P+O asymmetric service management method according to the present invention. Figure 6 As shown, a fifth embodiment of the P+O asymmetric service management method of the present invention is proposed based on the fourth embodiment. In this embodiment, step S23 specifically includes the following steps:

[0119] Step S231: Determine whether the service routing is asymmetric routing.

[0120] It should be noted that after setting the service route, it can be determined whether the service route is an asymmetric route.

[0121] Step S232: When the service routing is asymmetric routing, add the client service type in the mapping of the corresponding ODUk port, and obtain service download paths of different services according to the client service type.

[0122] It can be understood that when the service routing is asymmetric routing, the Client service type can be added through the mapping in the corresponding ODUk port, and then the service download path of different services can be obtained according to the client service type, and the routing setting is completed. When the service routing is symmetric, the service download path can be obtained through the pre-set normal process.

[0123] Through the above scheme, this embodiment determines whether the service route is an asymmetric route; when the service route is an asymmetric route, adds the client service type in the mapping of the corresponding ODUk port, obtains the service download path of different services according to the client service type, and can directly create an asymmetric service of the Ethernet scenario on the OTN, thereby improving the configuration efficiency and the speed and efficiency of P+O asymmetric service management.

[0124] Further, Figure 7 FIG. 6 is a flow chart of a sixth embodiment of the P+O asymmetric service management method of the present invention. Figure 7 As shown, a sixth embodiment of the P+O asymmetric service management method of the present invention is proposed based on the first embodiment. In this embodiment, step S30 specifically includes the following steps:

[0125] Step S31: Layer services at both ends of the P+O asymmetric service into ODUk / OTUk / OCH according to the service download path.

[0126] It should be noted that, when the asymmetric ODUK service is downloaded, the services at both ends of the P+O asymmetric service may be layered into ODUk / OTUk / OCH according to the service download path.

[0127] In actual operation, the service modeling on the P mode side remains unchanged, and the service modeling on the O mode side changes from the original four-layer CLIENT / ODUk / OTUk / OCH to the three-layer ODUk / OTUk / OCH. The original CLIENT service data implements resource configuration management at the ODUk layer.

[0128] Step S32: Add relevant overhead to the CLIENT service data at the ODUk layer, and perform resource configuration management on each layer of the P+O asymmetric service.

[0129] It is understandable that when downloading a service, it is determined whether it is asymmetric. If it is asymmetric, the CLIENT layer related overhead can be added to complete the service download. If it is symmetric, the service download can be performed according to the preset normal traffic.

[0130] In the specific implementation, when downloading asymmetric ODUk services, while downloading the original ODUK service related configuration data, it is necessary to increase the download of tributary disk related information ODUk overhead, physical port, system port mapping, cross-connection, and data service overhead (ODUk, OTUk).

[0131] Through the above solution, this embodiment layers the services at both ends of the P+O asymmetric service into ODUk / OTUk / OCH according to the service download path; adds relevant overhead to the CLIENT service data at the ODUk layer, and performs resource configuration management on each layer of the P+O asymmetric service, so as to directly create an asymmetric service of the Ethernet scenario on the OTN, improve configuration efficiency, realize lossless adjustment of the OTN asymmetric service bandwidth, adapt to the changing requirements of asymmetric service traffic, and improve the speed and efficiency of P+O asymmetric service management.

[0132] Accordingly, the present invention further provides a P+O asymmetric service management device.

[0133] Reference Figure 8 , Figure 8 This is a functional module diagram of the first embodiment of the P+O asymmetric service management device of the present invention.

[0134] In the first embodiment of the P+O asymmetric service management device of the present invention, the P+O asymmetric service management device includes:

[0135] The service creation module 10 is used to obtain the extended interface parameters of the OTN service and create a P+O asymmetric service according to the extended interface parameters.

[0140] The service creation module 10 is also used to generate service creation information according to the mapped Ethernet signal in combination with a preset EOO model; create a P+O asymmetric service according to the service creation information, set one end of the P+O asymmetric service to O mode, mark the service type as asymmetric, and select the P mode for the other end of the P+O asymmetric service.

[0141] The routing module 20 is further configured to check the service route crossing condition of the P+O asymmetric service according to the sink mapping mode; set the service route when the route crossing condition is crossing completed; and obtain the service download path according to the service route.

[0142] The routing module 20 is also used to determine whether the service routing is an asymmetric routing; when the service routing is an asymmetric routing, the client service type is added to the mapping of the corresponding ODUk port, and the service download paths of different services are obtained according to the client service type.

[0143] The management module 30 is further used to layer the services at both ends of the P+O asymmetric service into ODUk / OTUk / OCH according to the service download path; add relevant overhead to the CLIENT service data in the ODUk layer, and perform resource configuration management on each layer of the P+O asymmetric service.

[0144] Among them, the steps implemented by each functional module of the P+O asymmetric service management device can refer to the various embodiments of the P+O asymmetric service management method of the present invention, and will not be repeated here.

[0145] In addition, an embodiment of the present invention further provides a storage medium, on which a P+O asymmetric service management program is stored. When the P+O asymmetric service management program is executed by a processor, the following operations are implemented:
