2. Challenges and Opportunities
Challenges Opportunities
• Innovation at devices and OTT side • IP everywhere: BB/LTE, Core, Cloud
• Number of devices explode data and • LTE opportunity to re-engineer the network
signaling traffic with unexpected peaks and IT with frontier blurring
• Single purpose elements inflexible with • Cache, profile and inspect traffic more
high ASICs development cost efficiently
• Revenue trends for Comms Service • Virtualization and Cloud mature in the Data
Providers and Network Equipment Providers Center, SDN trend
force more cost reduction, operational • COTS servers now supporting Gb Ethernet
efficiency data processing

6. What is NFV
Network Function Virtualization: virtualize network functions
Leverage IT virtualization techniques
for telco functions
• Implement telco network functions in SW
• Use standard servers and storage
• Initiative from Tier 1 vendors launched as
a new Industry Specification Group (ISG) in
ETSI
Key Benefits
• Reduced equipment costs
• Faster time to market
• Resource sharing, agility (scale up/down)
• Centralized automated management
• Reduced TCO

7. What is SDN
- an emerging software based network architecture
Abstraction of control plane from forwarding
Applications hardware
• Network control plane as a centralized software program
• Centralized intelligence of network topology
Control Plane
Network API • Dynamic and programmable network, interaction with
applications
Network OS • Implemented via variety of methods including OpenFlow protocol
Key Benefits
• Provides opportunity for rapid innovation in networking
• Use cases for all types of networks including Enterprise Campus,
Service Provider, Cloud, Data Center
Infrastructure • Can enable simplified management through network
virtualization
SDN Model

8. Use Case Summary
Nb Name Description
#1 Appliance Migration Migrate proprietary boxes to COTS servers, decouple Data & control plan, leverage SDN
protocols, controllers, centralized controller for multiple data plane components etc
#2 Traffic Steering Introduce SDN with controller to extract 1st packets, tag flow and avoid having to redo
this for all packets. Allow dynamic change
#3 Content Delivery Traffic routing Allow dynamic traffic routing thanks to SDN controller and dynamic view of available
NW resources
#4 Virtual Core IMS Enhance Policy with tight integration with SDN controller to route traffic to virtual core
IMS
#5 Networking as a Service Extand IaaS with dynamic NW resource allocation and allow Telecom operators to offer
this as a Service to external customers
#6 Edge policy Enforcement Have a centralized control but distributed enforcement model for Security policies.
#7 Cloud Bursting Burst from Private Cloud to Public Cloud and be able to orchestrate the dynamic secure
network in the public cloud
#8 Optimal Traffic Engineering Inter-DC WAN Ability to have a Stateful controller to more dynamically place flows in the network, to
best utilize the network resources
#9 Data Center Virtualization Ability to move workloads around from any server to any other server within a DC
