Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an end-to-end ethernet service restoration method under a hybrid networking and a related device.
Background
PTN (Packet Transport Network) refers to an optical Transport Network architecture: a layer is arranged between IP service and bottom layer optical transmission medium, the layer is designed for the transmission requirement of burstiness and statistical multiplexing of packet service flow, the packet service is used as core and supports multi-service provision, lower TCO (Total Cost of Ownership) is provided, and the traditional advantages of optical transmission are simultaneously taken into consideration, including: high availability and reliability, high-efficiency bandwidth management mechanism and traffic engineering, convenient OAM and network management, expandability, higher security and the like.
As a key technology in 5G Network Slicing, SPN (Slicing Packet Network) is one of the best technologies for implementing a 5G transport bearer Network, and combines with a FlexE (flexible ethernet) technology to logically divide a 5G Network into independent subnets and ports, so as to meet application requirements of various people, objects, vehicles, and various private networks and reduce mutual interference caused by physical bandwidth sharing.
In the service provisioning architecture of the PTN and SPN networks, the upper layer is a network orchestration system, the bottom layer is Domain Controllers (DC) of multiple vendors, and ethernet services carried in the PTN and SPN networks have both single DC management and a situation of spanning multiple DCs. The management scope of different DCs is isolated, so in architecture, a Super Controller (SC) is also arranged between the network arranging system and each DC, and the Super Controller is in interface connection with the network arranging system and the DC through a uniform and standardized restful north-south interface. Specifically, the SC converts the service provisioning request of the network orchestration system into parameters of the DC southbound interface and adapts to the parameter differences of different DCs, and on the other hand, for services across multiple DCs, the SC is disassembled into multiple sections of services, and the DC southbound interface where each section is located is respectively called to automatically issue the services.
In the process of transition of a communication network from 4G to 5G, a mixed networking situation generally exists in the PTN and the SPN, and the difference of realizing Ethernet services under the PTN and the SPN is just shielded by an upper-layer programming system due to the existence of the SC. However, at present, the end-to-end path information of the ethernet service carried by the PTN and SPN networks is stored and restored by using the parameters when the SC is issued. When there is another system calling the DC delivery interface, or another system creates the ethernet service directly on the DC, the SC may miss the change of the end-to-end path information of the ethernet service, which may occur due to the above, thereby making it difficult to reconstruct the end-to-end link of the ethernet service.
