ONAP open source community

  5G is the next generation of mobile communications technology, its application will include all areas of social life and unmanned production car, the wisdom of factories / city, education and other industries, changes in the characteristics of the society is not an exaggeration. In the environment, 5G communications technology will work what kind of challenges?
  How network automation, allowing 5G become a network can simultaneously support multiple different dynamic services, a key factor affecting the stable development of 5G. why would you said this? In different application scenarios will require different network characteristics, as follows:
ONAP open source community
  support these various needs of the core technology called network slice, that is by creating a virtual private network for a specific service or customer service over a public network infrastructure. Further, 5G edge on request to the user computing application to thereby enable more dynamic environment. Therefore, put forward new requirements for network management and orchestration layers: first need to support both physical hardware (PNF) and virtual networking features (VNF) The 5G wireless network; secondly edge computing automation, 5G network core network services and elements VNF general deployed in large data centers, for 5G, centralized processing of wireless and core / edge separation of application processing is expected to create a large number of highly distributed edge computing position; there is the need for real-time optimization itself in response to user requests and network behavior in real time analysis of intelligence.
  5G 5G RAN automation includes the automation, automated 5G transmission network, the core network automation 5G three aspects, open source ONAP 5G provides a complete automation solution reference. ONAP support the initial feature set 5G, 5G cases related applications currently planned include: PNF Discovery and Integration, 5G network optimization and network fragmentation.
1. PNF Discovery and Integration
  5G physical network elements (DU) management needs to support Plug and Play, ONAP has developed a process for on-line registration of PNF. This step in the process is as follows: PNF modeling --PNF instantiation statement --PNF start initialization --PNF Contact ONAP - PNF activated.
2. 5G network optimization
  5G network performance optimization is achieved through dynamic configuration parameters 5G wireless network and backhaul networks. ONAP through multiple versions of its efforts to build an open 5G optimize the design and implementation of the ecosystem. The current list of features and optimization ONAP future 5G network include: real-time performance management --5G require a lot of time on the edge position frequently (less than a minute interval) from the sensitive performance management (PM) data for real-time analysis; non real-time batch analysis - -5G also need to address low (for example, every 5-15 minutes) batch PM data in order to optimize the frequency; resettlement --ONAP will find application-specific workloads best edge location; and zooming repair - with edges increasing nodes need concentration unit (CU) and other VNF automatic enlargement / reduction to provide a balanced network having an appropriate capacity, but also the need for self-healing; --ONAP edge automated computing node but also to achieve easy loading edge and registered.
3. Network fragment (Network Slicing)
  ONAP for 5G-related modeling work has already begun discussions with the community has been ONAP sliced cases moving forward.
  ONAP In addition to these community initiatives is also actively involved in service definition and management, dynamic network inventory management and coordination with 3GPP and ETSI model definition to enable providers to easily support multiple platforms.
  ONAP has achieved the first 5G features, including: support for registration and PNF PNF discovery, orchestration, life cycle management and monitoring; ONAP DCAE PM supports real-time data collection and papers collected PM batch data; close Multi-Cloud project with the SO integrated to simplify the edge of the cloud Onboarding; OOF project has many improvements to support the 5G requirements; Policy project support PCI closed-loop control and other requirements; modeling project has made progress in PNF descriptor resource information model aspects.
  5G is the key ONAP use cases. In view of the mobile user ONAP involved operators have accounted for more than 70% of global mobile users, and they can directly affect ONAP road map, which became final 5G network management automation and orchestration platform for ONAP paved the way.
