Metropolitan area network different-manufacturer business choreographer

Abstract

The invention discloses a metropolitan area network different-manufacturer business choreographer. The metropolitan area network different-manufacturer business choreographer comprises an applicationlayer, an access layer, a business layer, a service layer, a data layer and a physical layer; the application layer is used for initiating a business access request to the access layer, the access layer performs access control, access authentication, signature authentication logic analysis, and then initiates the business processing request to the business layer; the business layer performs flow processing related to the business, and then issues the business processing request to the service layer; the service layer performs adaption on the business processing request, and sends the businessissuing instruction to the physical layer; the physical layer sends the business issuing instruction to a different-manufacturer controller in the metropolitan area network, and presents the processing result on the application layer. The choreographer disclosed by the invention realizes the business flexible arrangement of the metropolitan area network, the abstract and package on various networkresources and the network capacity of the metropolitan area network are flexibly combined, the network capacity is opened, and the customized development is supported.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a business arranger for different manufacturers in a metropolitan area network. Background technique [0002] With the integration of fixed and mobile networks and the rapid development of government and enterprise services, the types of services carried by the metropolitan area network are becoming more and more abundant. With the rapid development and large-scale deployment of cloud computing, the future network will be centered on DCs and integrated locally. [0003] In addition, with the growth of the network scale, the number of network elements also increases rapidly, and the configuration instructions and styles of different manufacturers' equipment are different. Relying on the existing network element-by-network configuration mode, the workload is heavy, the configuration time is long, and there are many configuration levels. The configuration accuracy rate is not high, and ...

AI Technical Summary

Problems solved by technology

[0006] With the development of cloud computing, mobile Internet and other application modes and changes in traffic models, it is often necessary for the network to actively "adapt" to business traffic so that applications can change as needed. However, the current network management is mainly device-oriented Rather than business management, the perspective is more based on nodes rather than a global perspective. Therefore, many unsolvable problems have arisen:

[0009] There are many services, complex configuration, error-prone manual configuration, and long activation period;

[0010] (2) Traffic scheduling is difficult and lacks flexibility:

[0011] Due to the lack of perspective of the entire network, the devices select routes based on their respective routes, and the shortest route is selected instead of the optimal route, resulting in low bandwidth utilization; service flow routing cannot be automatically and quickly adjusted according to changes in network conditions, and user experience cannot be guaranteed.

[0012] Traditional policy routing and traffic engineering have large limitations and complex configurations, and cannot dynamically adapt to changes in network status and application requirements.

[0013] (3) The operation and maintenance experience of network maintenance personnel is poor:

[0015] There is no visual presentation of traffic and services, which makes it impossible to quickly identify and locate faults, making O&M difficult

[0016] (4) The network opening capability is weak and unable to adapt to the network requirements of the business:

[0017] The equipment is complex, the network is closed, and the programmability is weak, which cannot meet the needs of rapid service deployment and flexible customization
