Overview

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)...

Business Requirements

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.

Scope

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. 

Participating Companies

  • AT&T, Intel, Cloudify, China Mobile, Orange, ARM

Terminology Introduced

TermDefinition
Hardware Platform Awareness (HPA)The means by which the underlying NFV-I hardware platform capabilities are exposed to the network service orchestration and management functionality, for the purpose of fulfilling VNF instantiation-time hardware platform requirements.
HPA EnablementThe implementation of HPA awareness in ONAP.

Limitations



1

Specification of VNF's hardware platform capability requirements is limited to TOSCA based VNFD's.

2

Specification of VNF's hardware platform capability requirements using HEAT is not supported.

3

Supported capabilities are limited to the ones discoverable via OpenStack APIs.

4

Use of container based VNF placement is not supported.

5

Specification of capability requirements is bounded by the set of capabilities discovered in #2.

6

Implementation of southbound (Multi-Cloud) facing SO workflows is limited to HEAT only. 

7

Use of TOSCA based resource orchestration is a stretch goal.

8

There is no dynamic discozzzvery discovery of HPA capabilities.

9

HPA capabilities are not under monitoring.

Notes
1APP-CThere is no direct impact on APP-C, given that all instantiation actions are "outsourced" to the SO/OOF.
2VF-CChanges to VF-C will be required in order to incorporate use of HPA into instantiation and operation.

Test Plan (DRAFT)


Assumptions

VolTE and vCPE use cases will be used to validate the function of HPA end-to-end. The HPA test plans for Casablanca make the following assumptions with respect to function of ONAP components affected by HPA enablement functional requirement.

  1. There are no changes to the HPA capability discovery process.
  2. There are no changes to how discovered HPA capabilities are persisted in AAI.
  3. There are no changes to specification of HPA constraint policies used by OOF.
  4. Existing VoLTE and vCPE tests are sufficient to perform the end-to-end HPA testing.

Based on the above assumptions, the scope of the testing effort is limited to the following:
