IMS for Service Enablement

• SIP foundation of IMS as signaling protocol for
  application and user registration
• Simplifies service delivery
• Supports QoS assignment during application
  registration
• Application focus on
• Messaging
• VOIP

New Services Require More Than IMS/SIP

• IMS does not account for Web 2.0 and non-SIP
  applications
• Acknowledged in A-IMS initiative by Verizon
• Internet, Web 2.0 applications do not register
  with network, and are usually not hosted by
  service provider
• Value-Added Services often mimic web traffic
• New levels of network intelligence enable
  comprehensive offerings
• Subscriber/application awareness
• Tightly integrated service pipeline
• Detailed network visibility

• Intelligent service redirection

• Service Providers monetize full range of network
  applications
• IMS applications
• Web applications
• Over-the-top applications

DPI for Comprehensive Services Delivery
Signature over several packets found

• DPI enables detection of applications that may
  not be easily identifiable by traditional
  analysis
• Applications masquerading as web traffic/Port 80
  (P2P, messaging, streaming)
• Encrypted messaging and video (Vonage, Skype)
• Encrypted BitTorrent

Future Proofing Your Network

• DPI is the only technology that enables service
  providers to
• Control existing network traffic
• Monetize over-the-top applications
• Integrate NGN architectures with legacy
  applications without losing control
