Background
The PTN transmission circuit is mainly used for bearing 4G LTE and various special lines and is generally formed by splicing one or more PTN service paths. The service forms of the PTN service path comprise one source and one sink, one source and two sinks, two sources and one sink and two sources and two sinks, and the configuration methods of the service paths of all forms are different. The configuration of the PTN transmission circuit may be accomplished by a Super Controller (SC). With the increasing commercial provinces of the Super Controller (SC), the application scenarios of the PTN transmission circuits of each province are different, and when the Super Controller (SC) is used in a new province, the configuration function development of a new type of PTN transmission circuit needs to be performed according to the application scenarios of the new province. For example, the national prefecture B province of the controllers (SC) is the city of direct jurisdictions, with PTN devices divided into two administrative domains. The PTN transmission circuit for bearing the B province private line service is formed by splicing two sections of PTN service paths with one source and one sink, and each section of each management domain. The PTN transmission circuit for bearing the special line service in Z province crosses three management domains of city, province trunk and city, and is formed by splicing one section of PTN service paths with one source and two sinks, one section of PTN service path with two sources and two sinks and one section of PTN service path with two sources and one sink. The application scene of province F is cloud network fusion, and three management domains of city end access, city and province trunk are required under the scene, so that the PTN transmission circuit of the special cloud line is formed by splicing one section of PTN service paths with one source and one sink, one section of PTN service paths with one source and two sinks and one section of PTN service paths with two sources and two sinks. In the application scenario, the former Super Controller (SC) adopts a customized development mode. However, the customized development mode makes the new application scene support slower, and the accumulated links of the demand investigation, design, development, test and existing network deployment verification are about 1-3 months later, so that the efficiency is not high.

The invention provides a flexible arrangement device of a PTN service path, which is used for solving the problem of slow support of a new application scene. The technical solution of the invention is as follows: the Super Controller (SC) encapsulates a source-sink service path configuration, a source-sink service path configuration and a sink-sink service path configuration into four atomic capabilities, i.e. the configuration function of the four forms of service paths is encapsulated into four atomic capabilities, and provides the user with the flexible editing function. The user can flexibly arrange the four atomic capabilities through a page of a Super Controller (SC), and further flexibly arrange PTN service paths in four forms. The user only needs to design a PTN transmission circuit model supporting the scene according to the new application scene of the province. The design of the model requires that a user extracts and splices PTN service paths in four forms by combining the actual situation of the current network, and each spliced PTN service path is equivalent to an atomic capability combination. The model design is good, and the corresponding relation from the new application scene to the PTN transmission circuit model and the corresponding relation between the PTN transmission circuit model and the atomic capability combination are established. And after the Super Controller (SC) receives the work order, reading the type of the application scene from the work order information, searching a corresponding PTN transmission circuit model according to the type, and configuring each PTN service path according to the model, so that the PTN circuit under the scene can be switched on. The application scenarios of 4G LTE and various private lines are different in each province for each path configuration requirement of the PTN transmission circuit, but the PTN transmission circuit is a combination of the above four types of service paths regardless of changes. The original idea is to customize and develop according to the requirements of a new application scene of a certain province, and the mode needs a 1-3 month lead time and has long time. The Super Controller (SC) encapsulates the atomic capability configured by the PTN service paths in four service forms by adopting a mode of encapsulating the atomic capability, and simultaneously provides a design function of a PTN transmission circuit model, and the model can flexibly arrange the atomic capability, namely flexibly arrange each segment of PTN service path. According to the requirement of the province application scene on the PTN transmission circuit, users in various provinces arrange various paths of the circuit, design a new PTN transmission circuit model and combine different atomic capabilities, as shown in figure 5. And when the PTN transmission circuit is switched on, the Super Controller (SC) selects the capability combination corresponding to the type according to the type of the application scene to configure each section of service path. And each section of path of the PTN transmission circuit can be defined in a flexible arrangement mode in the new application scene, so that the requirement of rapid online of the new application scene is met. According to the scheme designed by the invention, the atomic capability combinations corresponding to the configuration functions which are customized and developed for the provinces B, Z and F are shown in the figures 6, 7 and 8.
A flexible arrangement device for PTN service paths is characterized in that a Super Controller (SC) encapsulates four atomic capabilities of one-source one-host service path configuration, one-source two-host service path configuration, two-source one-host service path configuration and two-source two-host service path configuration. A user designs a PTN transmission circuit model according to a new application scene of the province, splices all sections of PTN service paths and forms a new capability combination in a Super Controller (SC) system. And the Super Controller (SC) reads the application scene type in the work order information, a corresponding PTN transmission circuit model is taken according to the application scene type, and the Super Controller (SC) calls each atomic capability according to the atomic capability combination corresponding to the model to carry out circuit configuration. The Super Controller (SC) provides the function of designing a PTN transmission circuit model for a user, flexibly arranges and combines all PTN service paths, further replaces a mode of customizing, developing and supporting a new application scene, and greatly shortens the online time of the new application scene.
