Challenges and Opportunities

Challenges

• Innovation at devices and OTT side

• Number of devices explode data and signaling traffic with unexpected peaks

• Single purpose elements inflexible with high ASICs development cost

• Revenue trends for Comms Service Providers and Network Equipment Providers force more cost reduction, operational efficiency

Opportunities

• IP everywhere: BB/LTE, Core, Cloud

• LTE opportunity to re-engineer the network and IT with frontier blurring

• Cache, profile and inspect traffic more efficiently

• Virtualization and Cloud mature in the Data Center, SDN trend

• COTS servers now supporting Gb Ethernet data processing

What is NFV

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

Network Function Virtualization: virtualize network functions


What is SDN

Abstraction of control plane from forwarding hardware • Network control plane as a centralized software program

• Centralized intelligence of network topology

• Dynamic and programmable network, interaction with applications

• 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

• Can enable simplified management through network virtualization

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 without limitations of the network addressing
