1 What is NFV

3 Key components of our solution

4 Summary


› Founded in Nov 2012 by 13 leading operators

– Over 150 members

› Accelerate the materialization of Virtualization

– Promoting knowledge sharing and consensus in the industry

– Recommending requirements to Standards Development Organizations (SDOs)

Network Function VirtualizationThe objectives

Network Function Virtualization Industry Specification Group

› Discuss target reference architecture and building blocks

› Pilot Network Virtualization technology through concrete use cases

› Plan transformation – technology & operational organization

Leading operators driving the industry to prepare for transformation


Virtualizing telconetwork functions› Improving time-to-market

– minimizing the typical network operator cycle of innovation.

› Optimizing resource utilization– reduce equipment cost, space, and power

consumption.

› Improving operational efficiency – automation and intelligent platforms.

› Elasticity and scalability– Dynamic demands imposed in a multi-tenant

environment.

› Encouraging openness– Enable multi-vendor interoperability of hardware and

software.

› Ericsson already using industry standard virtualization, processors and switches

– Aligned with the NFV vision.

› Challenge when developing network functions is securing reliability, availability and performance:

– If SW and HW procurement is separated, who is accountable?

Telco Cloud Execution EnvironmentRationale

1. Stringent performance requirements– Network throughput, latency– Real-time scheduling in the

hypervisor– Load balancing

2. High availability– High availability for the execution

environment – High availability for the

applications3. Fault and performance

management 4. Security and isolation

– Including performance isolation– Specific firewall rules and

configurations5. SLA guarantees and fulfillment
