VNF Manager

VNF

EMS

OSS

Logical environment



Activation flow of control

1. Request for lifecycle change

Could come from OSS, EMS, external VNF Manager, or autonomous action

2. NFV Director applies policies

3. NFV Director requests VIM to perform action

Request could involve multiple VIMs

For networks not managed by VIM, NFV Director could make changes through an SDN controller or directly to the NW devices

4. VIM manages changes in the infrastructure

5. NFV Director configures monitoring, correlation, and autonomous actions based on policy

Simplified and generalized view

VNF Manager

VNF

EMS

OSS

Logical environment



Monitoring and autonomous action flow of control

1. HP NFV Director continuously monitors defined KPIs

KPIs can include physical and logical infrastructures, network, application components, etc.

Monitoring is based on KPIs defined for that VNF instance, configured as part of VNF activation

2. HP NFV Director applies threshold on collected metrics, generating events when thresholds are crossed

3. HP NFV Director maps infrastructure events to VNF-specific virtual infrastructure events

Events from other sources can be included in the correlation

4. HP NFV Director executes autonomous actions based on rules defined for the event

Rules can be based on specific sequence of events or other conditions

Actions can be directed at NFV Director or external systems

5. HP NFV Director provides events to interested parties

This could be OSS, EMS, VNF Manager, or other entities

6. EMS directly monitors application faults

Provides information to OSS or NFV Manager

If this needs to be visible to the NFV Director, it can be fed directly into correlation engine

Example HP NFV Director case study


VNF Graph example

HP Contribution on IMS MRF being approved for MANO GS

IMS MRF is a VNF Graph

Containing 2 VNFs: MRB and MRF

MRB is a single component VNF

MRF has 2 components

MRF C+P have been grouped together as they are deployed on same VM

The 2 components have different redundancy models

VNF Descriptor example

Deployment requirements Active/Standby redundancy model

VM number: 2 instances

vCPU and vRAM needed

Availability rule to force to deploy the 2 instances on 2 VMs located on different physical hardware resources.

Highly Available IP network

Operational requirements Support of typical lifecycle operations: provision, scale up/out, start, stop and delete

Relationships: 2 external relationships: Relation MRB – MRF-C

Relation MRB – S-CSCF. An S-CSCF should be present in the overall solution, but it is not part of the MRB VNF and it might not even by a virtualized component.

Using MRB

IMS MRF use case

Logical environment

Physical network Physical compute & storage

HP NFV Director – Functional Overview

1. Operator or App EMS requests provisioning request for application instance using one of the predefined templates

2. HP NFV Director iterates through the template and issues create server requests

3. For each request, HP NFV Director instantiates resource and loads app instance

4. HP NFV Director continuously monitors physical & virtual resource performance of the virtual infrastructure HP NFV Director maintains the mapping between physical resources, virtual resources and application instances and maps NFVI KPIs to application instances HP NFV Director must be aware of application HA model to deploy app instances correctly and avoid single point of failure

5. Resource KPIs reported back to App/ App EMS. Application KPIs monitored by App/ App EMS

6. Closed-loop to fulfillment (manual or automated) - App-specific resource and/or application KPI thresholds triggers adjustment requests (scale up/down, out/in of resources)
