Carrier SDN and NFV Strategies
IIR SDN & NFV 2013, 2-October, Prague
2 2
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
API
Control plane abstracted
from data plane

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
