Challenges of Todays Telecom Network and NFV Adoption

High Network Intricacy

• Time to deploy Multiple acquisition, resulted in complex, fragile network topologies

• Multiple upgrade paths & maintenance schedules

Agility Low flexibility

• Underutilized network resources can not be used for any other function network

• Each of the infra elements having its own proprietary set of commands, API and integration techniques

Efficiency

Infrastructure

integration difficultiesDifficult to Manage

multiple EMS, units

Customer experience Time to marketHigh availability

• CSPs would adopt NFV to

address these challenges

• Adoption would be in

phased manner. Can start

with Virtualization of Core

and Edge and then moving

towards end points or vise

a versa.

• Both Hardware networks

(legacy) and NFV would co-

exist for some more years

• Training / Upskill / cross skills of

AS-IS resources

• Rebadging and operating Legacy

• Automate, Automate and Automate

• Shared

• Incident management

• Service owners on-call

• Tight integration

• Continuous

Software Skills



Implications on People Process Tools

People Process Tools

• Network operational skills to

software skills.

More programming and scripting

knowledge in addition to specific

network function knowledge

• Roles and responsibilities will

mutate

• Company culture to change

• Business processes re-alignment

• Establishing and realigning

operational workflows which will

address points of failures in timely

manner to meet the SLAs

• Integration & automation between

legacy and NFV environment

• Consolidation plan and Integration

with existing platforms with focus

on Standardization and

Compliance

• Holistic security designs to be

relooked

• Monitoring capability of VM layer,

NFV apps performance,

Interconnect performance etc.



Roles & Responsibilities

• The CTO and CIO will remain as two separate roles particularly in large operators — but might merge under a CTIO

group after complete adoption and maturity.

• The CIO’s organization increasingly takes on network operations while the CTO’s responsibilities become future focused.

• New roles would be created

CTO CIO Emerging Roles CMO

• Future focused

• Legacy migration

• Biz and network impact due to adoption of new technologies

• Operations focused

• Takes on more ops responsibilities (SF & SA)

• DevOps Engineers

• IT generalists

• SDN Engineers

• Cloud orchestration engineering

• Technical & feature focused

• Works closely with CIO org



Ideas To Manage Transition Smoothly

• Managed Services providers can be leveraged to handle legacy operations

• Managed service providers can contribute to great extent in testing, integration of new automations.

• Managed services operators can help achieving cost effective structures for carriers in SDN and NFV journey

Focus on process

re-engineering while

adopting NFV

Engage a MSP to

handle legacy

network while CSP

focusses on adoption

of NFV

Involve MSP in

migration process so

that NFV network

can be managed

more effectively in

future

Build KEDB from day 1

for successful NFV

Adoption.
