  3. 3. 3A network of depth and breadth• High capacity long distance network - 43,000km• Connecting 22 countries, 39 metro networks and >150 cities• 20 data centres and 19,000 connected buildings• B2B only – no MNO

  7. 7. 7Software Defined NetworkingColt’s SDN vision is internally defined as “Network Programmability”and has two main components:1) Bring computing paradigm to networking: make the network elastic,scalable, on-demand and virtualised2) Allow Application layer to communicate, through standard APIs, withthe networkThe target is to integrate in the long term IMS functions,UC and other applications within the SDN architecture• Fully virtualised deployments on our standard compute platforms• APIs for QoS, CAC, DPI, provisioning, billing etc. to allowapplications and network to talk
  8. 8. 8Future Voice PropositionsThe OTT Question:B2B ≠ B2C• Regulatory (emergency calls, LI)• Functionality (dialplans, CLI, IN, etc.)• Resiliency (enhanced routing, disaster recovery)• End-to-end QoS… but for how long ?… what about UC ?… what about WebRTC ?
  9. 9. 9A new Aspect of OTTWebRTC brings a new aspect into the OTT discussion: Will WebRTC change the OTT landscape? Is WebRTC a threat or an opportunity for Colt?
  10. 10. 10What does WebRTC mean for Colt?• ‘real’ click-to-call• Extending PBX DDI numbers to the web• Integration with audio conferencing / WebEx• Integration with UC and video conferencing• Contact center solution enhancementsExtend existing products to native web-browserswithout plugins1/3Phase 1: Service EnrichmentBeing prototypedin Colt !
  11. 11. 11What does WebRTC mean to Colt?• Virtual PBX• Next-gen UC• Next-gen video conferencingWeb-based realtime communication(… w/o the need for a E164 number)2/3Phase 2: Possible future SolutionsHow will this impact the architectureand functionality of the futurecommunications core platforms?
  12. 12. 12What does WebRTC mean to Colt? 3/3Phase 3: Future Core Infrastructure How does the future Voice/VoIP environment look like?• Large web-servers instead of an IMS core?• How will WebRTC be integrated in IMS? What about current developments?• Do we need nat’l VoIP I/Cs with PTTs or will it be Internet? (*)• Should we further (heavily!) invest in Number Portability?• Etc…(*) we have been asked this question by a PTT!
  13. 13. 13Summary• Functionality of SIP trunks is there, next step is to reduce complexity• IMS and UC platforms covered in the long-term by Colt’s vision ofNetwork Programmability (SDN)• B2B SIP trunking less impacted by OTT so far due to more stringentrequirements, but this may change over time• WebRTC has the potential to impact our future service offering andinfrastructure architecture• The next 2-3 years will show if WebRTC becomes a game changeror if it was a simple distraction
