This is page is being used to track the realization of the Hardware Platform Awareness (HPA) functional requirement defined in support of VoLTE, vCPE and 5G use cases. The requirement calls for enablement of hardware platform feature awareness (HPA) inside the ONAP management platform, or means by which knowledge about underlying compute hardware platform capabilities is exposed to VNFs running on top of the platform in order to optimize, accelerate and/or otherwise augment their execution. In ONAP, HPA enablement focuses on discovery, health monitoring and configuration of hardware platform capabilities within the NFV infrastructure, and their consumption by the virtual network functions and network services deployed on top of the infrastructure.
More Information (Intel-specific)...
This requirement is required in support of commercial VNF implementations, that are used as part of vCPE, VoLTE and 5G use cases, and require hardware assisted acceleration. This requirement is also needed by the ONAP Optimization Framework (OOF) project in order to optimize homing and placement of hardware assisted VNFs.
The scope of this requirement is limited to consumption of hardware platform capabilities for the purpose of VNF performance acceleration and optimization. Other uses of HPA are not in scope.
