Telco-OTT: infrastructure challenges and solutions

  1. 1. Telco-OTTinfrastructurechallenges &solutions Victor Pascual Solutions  @victorpascual  h9p://   Feb  2013  
  2. 2. Acme Packet – leader in sessiondelivery network solutions§  Mission: enable delivery of •  Founded: 2000 trusted, first-class interactive •  HQ: Bedford, MA USA communications and data services across IP networks •  NASDAQ: APKT •  2011 revenue: $307M •  2011 net income: $72M§  Solutions to enable •  850+ employees all-IP evolution §  Increase revenue §  Lower total cost of ownership §  Maximize network agility§  Experienced §  1,850 customers §  150 IMS projects 2
  3. 3. Now there is 3 ways to make a call What  does  a  RTC  feature  look  like?  phone service   Acme Bank Sign off app service   feature   APKTbrowser service   feature   Call Broker 3
  4. 4. OTT usually seen as a threat. The clock is ticking… 4
  5. 5. Changing telco response to OTTOld§  The OTT threat is miniscule§  Those are low-value minutes§  Those are not minutes that would have been on my network anyway§  OTT’s don’t make any money§  Our IMS services will be betterNew§  What if IMS (& VoLTE/RCS) doesn’t work? Existing customers Existing and NEW customers§  How do I encourage more data usage?§  Can we get in on the OTT action? Innovation speed is critical 5
  6. 6. OTT service delivery challengesImmediate ImminentPractical core session Flexibilitymanagement • Quickly adjust to changing service needs • Works with many infrastructure & client• Cost effective at low & high-end devices• Able to start small & grow rapidly • Federates with network service providers SecurityService quality • Protect user information • Maintain service availability during• NAT & firewall traversal (i.e. HTTP & attacks HTTPS only)• Near PSTN-quality – media & Regulatory compliance availability • Current expectations: E911, lawful• Consistent experience across devices intercept, taxes & interfaces • Expect more IP network regulations, not less 6
  7. 7. OTT service delivery implicationsImmediate ImminentPractical core session Flexibilitymanagement • Off-the-shelf, but programmable for flexible, rapid changes• Light weight, dynamic core session management • Quickly interoperable with any device & network• Smarter clients vs. omnipotent core for scalability SecurityService quality • Robust, service-intelligent security• Client-side technologies to overcome packet-loss & jitter• Make all traffic look like web- Regulatory compliance traffic (http & https, SSL, etc.) • Out-of-the box regulatory compliance 7
  8. 8. What are the leading servicedelivery architectures? 3GPP R10 IMS Web DB DB AS AS AS WS WS WS WS LB-L LB-G Internet 8
  9. 9. Telco-OTT architecturesshould be web-like Web Telco-OTT DB DB DB DB AS AS AS AS AS DSC Peering partners WS WS WS WS SMX SMX SMX LB-L LB-G LB-L SLB-G Managed IP Internet Internet Network 9

  12. 12. Simplicity should not precludeecosystem interoperability TAS CS ENUM ISC SIP DNS/DDNS ISC IM&P Cx HSS SIP MCU Rx PCRF SIP WebTRC TSCF SBC & Core session management Web-based RTC SIP clients 12
  13. 13. Telco-OTT services are already here…and delivering successful services in time-spans of months 13
  14. 14. Reaching users over the Internet§  Acme Packet’s Tunneled Service Control Function (TSCF) brings Services §  Reliability Service provider data center §  Scalability §  Security Web   SIP   MSRP   §  Firewall traversal §  Mobility §  and QoE to Internet-based Apps Internet Services   Best  Effort   Firewall   Access Network Packet  Loss   14
  15. 15. What is WebRTC?§  What is WebRTC (Real Time Communications)? §  Emerging method of web-based RTC §  Another type of access framework, same session delivery challenges§  Why the hype? §  Web: most dynamic, innovative place on planet §  RTC has largely been absent §  WebRTC delivers RTC to those that create the Web§  Why should you care? §  WebRTC will be an important access method in the future for SPs, contact centers, and enterprises
  16. 16. Telco-OTT increasescustomers & revenue Expand footprint - Extend existing services to new subscribers Decrease churn - Enhance current services to existing subscribers New service revenues – Create new services and subscribers 16
