Challenge Today: Implementation of L4-L7 services in Connection Oriented Model
InternetVirtualized SGi Svcs Platform
App Services
VideoOptimisation
Transparent Caching
URL Filtering ParentalControls
Today’s Challenges:• Static Service Chaining – not reprogrammable• Complex to manage & automate provisioning• Lack of metadata to automate & scale

The 4 pillars of Integrated SDN and NFV
SDN+NFV
Virtualization• Virtual network functions
(VNFs/VMs)• Significant multi-tenancy• High performance• Comprehensive
hypervisor support
Abstraction• Service and network
abstraction• Configuration
templates• On demand
resourcing
Programmability• Data, control &
management planes• Open and
production-deployed APIs
• Developer-friendly RESTful APIs
• Large existing developer community & ecosystem
Orchestration• Unified multi-vendor, multi-service ecosystem
• Open and standards based multivendor integration
• Policy-driven flows and steering
