Summary:
|
With the development of network and service, more and more value-added services need to be deployed and dynamically adjusted on demand, such as network security services, including FW, WAF, DPI, etc. Initially, various services can be deployed in the central cloud resource pool. With the continuous improvement of network performance requirements such as network quality and request delay, the increasing demand for flexible increase and decrease of service functions, and the development of edge computing technology, operators deploy security service functions on several edge nodes as required. Edge nodes collaborate through the network and use SFC technology to connect service functions, meeting users' demand for flexible scheduling of service functions, further shortening response time, optimizing resource layout, and improving network efficiency.
Based on the scenario of service function chaining, it’s necessary to initial a work item on signalling requirements and data models of service function chaining orchestration, which is used to define interface requirements and data models between network controller, cloud controller and service orchestrator.
