Virtual Network Functions located at CSP PoP
Centralized Model
• All Virtualized functionality located at CSPs PoP (DC/CO).
• VNFs deployed using existing networks.
• Carrier Ethernet is ideal for providing access to centralized
VNFs from the customer premises
• Basic Switch/Router at the customer premises.
• Heavy reliability on the cloud and network performance.

• VNF Image update management.
• Manage group of VNFCs belonging to the
same VNF instance.
VNF Managers are seen tightly coupled with other MANO components. But they are intended to be loosely coupled and have
distributed implementation scope.

Understanding em-vnf-vnfm
• Element Management System (EMS) manages the VNFs in co-ordination with
VNFM.
• Ve-Vnfm-em – Provides the Interface for EMS to support various operations
(LCM, Fault, Performance, Configuration etc..) produced by VNFM.
• EMS are specific to the VNFs and are provided by VNF vendors.
• EMS act as VNF specific managers by supporting various operations from
VNFM.
• Ve-Vnfm-Vnf – Provides interface for VNF to support various operations
produced by VNFM.
• Provides a direct communication to VNF management.
Reference: [ETSI GS NFV-IFA 008 V2.1.1 (2016-10)] Network Functions Virtualisation (NFV); Management and Orchestration; Ve-Vnfm reference point - Interface and Information Model Specification
While VNF Centric management approach is a required, VNFMs can take fair share in managing VNFs. Moving forward, VNFMs
will need to manage multi vendor VNFs. Standardized specification is still in literature.

Future VNFs
Containerized VNFs
• Reduced Overhead
Microservices,
• which enables service
composability, reusability,
efficient scaling and ease of
deployment
Stateless processing
• Makes cloud VNFs fault
tolerant and scalable without
notional limits – Application
isolated from state.
Easy Orchestration
• VNFs are designed to
minimize the amount of
configuration needed in each
component.
Monolithic VNF
•VNF combined with all
the
components
Minimal Reuse
•VNFC level re-usability is
minimal or no
Stateful
•The states are tightly
coupled with the packet
processing unit itself,
Orchestration
•VNF orchestration is
dependent on VNF
Complexity.

VNF Manager - Tomorrow
Today … Tomorrow..
VNF Management Centralized Distributed NFV, Edge NFV is evolving. VNF
management must change scope.
VNF/EMS/VNFM from single providers Complex decomposed VNFCs from multiple
providers
EMS to manage VNFs EMS based VNF management faded. VNFMs
to managed decomposed shared VNF(C)s.
Security management centralized Distributed Security management - VNF and
NS centric.
Intelligent VNFs – Still in literature Intelligent VNFs – a Reality
With the adoption of VNF decomposition to microservices and evolving Telco needs, Cloud Edge and
Customer premises equipment management requires localized control for low latency and Service agility.
This expands the view of VNF management.

CED is the first entry point from the end-user/subscriber to
connect to a network and subscribe a specific service.
Legacy CED, are deeply hardware and software coupled and
recently IPTV, VOIP, remote storage was introduced making
CEDs more sophisticated.
Today CEDs are made more intelligent with NFV, there by
dynamically provision new services into CEDs.
D-VNFM is a best fit solution to provision, manage and monitor
VNFs with improved service security, reliability and proactive
resource management.
Since IoT is moving fast in residential market, DVNFM can
improve overall deployment flexibility and generate potential
benefits to the complete ecosystems
Intelligent VNF
With advent of data analytics and machine learning it’s
possible to foresee the improvements needed to
manage the networks with experience from existing
data.
This requires a local management of VNFs and their
underlying networks and infrastructures.
Distributed management of VNFs using analytical tools
paves a new path for sophisticated and intelligent
management of resource.
This helps improve fault tolerance, better availability
and resiliency at complete infrastructure.
Since VNFs are split into fine granular VNFCs
integration with Data Analytics/learning systems will
surely benefit the ecosystem.
D-VNFM - Benefits
✓Efficient, localized and unique services for VNFs
✓Managing different VNFs from different VNF vendors
✓VNFC and Network Service Centric Security
management.
✓VNF management in and across trust domains.
✓Using DA/ML for effective utilization of VNFs and
resources
✓Fast instantiation and increase resource utilization
✓Agile VNF software upgrade
✓Addressing E2E automation

Future work
• Detailed Design and architecture.
• PoC with ETSI proposed use-cases.
• API definitions and Communication end point design.
• Plugin architecture for External app integration.
• Realizing with OpenStack modules.
That’s all folks.

Customer Edge Device Management Diagram Source: http://www.nxp.com/assets/documents/data/en/supporting-information/DN-Digital%20Networking%20solution-2017.pdf CED is the first entry point from the end-user/subscriber to connect to a network and subscribe a specific service. Legacy CED, are deeply hardware and software coupled and recently IPTV, VOIP, remote storage was introduced making CEDs more sophisticated. Today CEDs are made more intelligent with NFV, there by dynamically provision new services into CEDs. D-VNFM is a best fit solution to provision, manage and monitor VNFs with improved service security, reliability and proactive resource management. Since IoT is moving fast in residential market, DVNFM can improve overall deployment flexibility and generate potential benefits to the complete ecosystems
  • 18. Intelligent VNF With advent of data analytics and machine learning it’s possible to foresee the improvements needed to manage the networks with experience from existing data. This requires a local management of VNFs and their underlying networks and infrastructures. Distributed management of VNFs using analytical tools paves a new path for sophisticated and intelligent management of resource. This helps improve fault tolerance, better availability and resiliency at complete infrastructure. Since VNFs are split into fine granular VNFCs integration with Data Analytics/learning systems will surely benefit the ecosystem.
