ONAP Beijing Release Developer Forum

As NFV deployment expanded from central cloud to the edge, also with the trends of Cloud Native and MEC, there are increasing requirements for the NFV network support of mixed infrastructure resources, include: VMs, Containers, Bare metals, hardware accelerators (e.g. SmartNIC), dedicated PNFs etc. To enabling 5G RAN and EtE network slicing support, ONAP need the capability to be aware of the mixed infrastructure resources with generic data modelling description. Also need to extend orchestration and control capability to the PNFs and intra-cloud/CO site, to keep the consistency of network attributes and QoS guarantee of network slicing services. With the current limitation of VIM layer which mainly focus on the management and orchestration of virtual resources, limited awareness of the cloud infrastructure underneath, there are solid gaps for Service orchestration and VNF controllers to be aware of and consume the mixed cloud resources, especially when across domains. Expose the cloud infrastructure in a unified model driven way, also enrich the A&AI with an elastic, accurate, up to date infrastructure resources descriptions based on common data model template. Which can be further consumed by a cloud site/local controller to support EtE automation and hierarchical network control will achieve the agile, low latency, fast auto-scaling and other new requirements from 5G and MEC.
