The collaborative management and control model is connected with the FlexE/SPN network model through a pre-configured resource management interface, a topology management interface and a routing calculation interface and is used for acquiring and managing network resources, topology structures and routing information of each electric power FlexE/SPN network;

In one embodiment, the service configuration interface comprises: the CBR service configuration interface and the ETH service configuration interface are respectively used for issuing corresponding CBR service configuration parameters and ETH service configuration parameters.

Of course, in the actual operation process, each FlexE/SPN network corresponds to one SPN domain management and control system. In this embodiment, regardless of the number of FlexE/SPN domain management and control systems connected to the collaborative management and control system, a preset northbound interface may be used to uniformly manage and control FlexE/SPN networks associated with each FlexE/SPN domain management and control system.
In an embodiment, the collaborative management and control model is further connected to the SPN domain management and control system through a preconfigured synchronization management interface, and is configured to synchronize resource information of the power FlexE/SPN network connected to the FlexE/SPN domain management and control system.

Firstly, synchronizing resources, including clock information, network elements and ports of the network elements, for example, adding a board card, an optical module and other component information at a device end of a manufacturer, and synchronizing the component information to a TMS so that the TMS can know the component information in time and manage the component information. For another example, the clock information of the network elements in the two devices are different, and synchronization of the clock information can be achieved through a synchronization interface.
According to the technical scheme, a cooperative management and control model is configured in a cooperative management and control system, and the cooperative management and control model is connected with a FlexE/SPN network model through a pre-configured resource management interface, a pre-configured topology management interface and a pre-configured routing calculation interface, so that network resources, topology structures and routing information of each electric power FlexE/SPN network are acquired and managed; the method comprises the steps of connecting with a tunnel model through a pre-configured tunnel configuration interface, and transmitting corresponding tunnel configuration parameters based on routing information and tunnel types required by power grid services; the method comprises the steps of connecting a channel model through a pre-configured channel configuration interface, and transmitting corresponding channel configuration parameters based on route information and channel types required by power grid service; the method comprises the steps of connecting a service model through a pre-configured service configuration interface and transmitting corresponding service configuration parameters based on routing information, tunnel configuration parameters and channel configuration parameters; the method comprises the steps of connecting an alarm model through a pre-configured alarm management interface, inquiring current or historical alarm information, and configuring corresponding alarm shielding parameters; the method is connected with the performance model through the pre-configured performance management interface, is used for inquiring the current or historical performance and configuring the corresponding performance acquisition parameters, solves the technical problem that the unified interface and standard management and control of the different manufacturer FlexE/SPN network cannot be adopted in the prior art, and achieves the technical effect of unified management and control of the different manufacturer FlexE/SPN network.

In an embodiment, when configuring a power grid service between two network elements, a sink end and a source end need to be selected, whether to cross-domain is determined according to network element information, and whether the two network elements belong to the same manufacturer is determined. The EMS of each manufacturer can generate a specific network data from the associated FlexE/SPN network, and report the specific network data to the TMS, wherein the network data has a unique identifier, namely UUID.
