Infonetics Definition: SDNs Are Subset of Programmable Networks

SDNs enable networking applications to request and manipulate services provided by the network

and allow the network to expose network state back to the applications

2 common types of SDNs

Why Service Providers Want SDNs & NFV

Top Drivers

New revenue and operational efficiency drive SDN/NFV

#1 Service velocity (100%)quicker time to new revenue

#2 Simpler provisioning over multivendor networks

#2 Lower OPEX with master view over multivendor, multilayer

Corollary: global view and network intelligence means networks can

run hottersaves CAPEX

Corollary: global view and subscriber intelligence means quicker new services and new revenues

Translation: we need more automation and new paradigm

Strategy to Deploy SDNs

5

82% Plan to deploy SDNs in their

existing networks, not just in

greenfield networks

Hybrid SDN is critical

Likely Domains for Deployments

Prioritized list of SDN target domains:

DC-related: intra-DC, inter-DC, cloud services

Consumer/business services via virtual CPE, a.k.a., cloud box

Optical transport

EPC/mobile core, BNG/BRAS, mobile backhaul,

metro aggregation

Contained DomainsData Centers Are Easy

Service providers are inspired by DC SDNs as proof of concept

3 years of Google resources/investments + Nicira smarts

solves operational problems of data center environment

SDNs work!

DC is simple contained domainwhile service provider networks are much more complex

Much bigger challenge / much bigger payoff

SDNs will take time

Conclusions: SDN-NFV Here to Stay

A network is a collection of elements/nodes and EMSs using many technologies, protocols, and architectures, using multivendor equipment

For SPs, SDN and NFV create a new paradigm for network operations and services

New levels of innovation not possible with current technologies

New revenue and operational efficiency drive SDN/NFV for SPs

Global network view and intelligence means networks can run hottersaves CAPEX

Global network view and subscriber behavior data means new services and quicker

revenues

Many operators are testing, doing proof of concepts (PoCs), learning, and some are pushing toward initial commercialized services or network operations based

on SDN and NFV

SDNs and NFV are a fundamental change that will take many years for transformationbut operators are starting now first in targeted contained domains
