• Relatively static infrastructure

• OSS focussed primarily on

resource management

• “Just enough” service

• Complex Design/Assign

activities

• Solution design required

NFV/

SDN

NFV/SDN is going to just

be another casualty of

OSS integration projects

NFV/SDN based services

will lose any form of agility

or responsiveness

It will be harder to support

the hybrid IT cloud model

most of our customers will

embrace

Call to have a successful revolution

Call to OSS/SDN/NFV Vendors and Open Source Developers

15

Make SDN/NFV products

smarter and more

focussed on the

operational management

of the service

Agree on a declarative,

common north bound

abstraction model that

allows us to simplify the

OSS/BSS integration

problem

Help us simplify the OSS

to deliver dynamic

services

Help us enhance our

services using real-time

analytics and continuous

feedback not rules or

offline analysis

Thankyou For your time
