  1. Host media processing – revisited Faye McClenahan – Aculab

  2. Agenda • What is host media processing (HMP)? • HMP in a mixed TDM/IP environment • The choice between DSP-based and host-based media processing • The future of HMP • Summary

  3. What is HMP? • Host media processing – performs all the tasks traditionally performed on a DSP

  4. Background Processor power 1964 2006 2014 Time

  5. What is HMP? • HMP is now viable • Faster roll out of features • Riding the consumer wave rather than the specialist wave

  6. Why HMP? • Key advantage – it’s software-based • Flexibility and speed of deployment • Channel counts • No hardware • Cost efficiencies • New application opportunities

  7. What applications can be based on HMP? • All traditional applications • Voicemail, IVR, conferencing, broadcast, contact centre, etc. • New IP-centric applications • Free from TDM and hardware constraints

  8. What to look for in an HMP product • High channel counts per standard processor • Simple pricing and licensing structure • Choice of operating system • Compliance with IETF standards • Not restricted to a particular make of processor

  9. What to look for in an HMP product • Protocol support – SIP, H.323 • Wide portfolio of codec support – iLBC, G.711, G.729AB, G.726, G.728, GSM-FR, etc • Choice of operating system • Comprehensive set of media processing resources • Security – Secure RTP, TLS, SIPS, NAT traversal

  10. Agenda • What is host media processing (HMP)? • HMP in a mixed TDM/IP environment • The choice between DSP-based and host-based media processing • The future of HMP • Summary

  11. HMP in a mixed TDM/IP environment • Best suited to pure IP environments • Adoption of VoIP accelerating fast • Proliferation of VoIP • Skype • Vonage • Jahjah • Wireless Internet

  12. HMP in a mixed TDM/IP environment • How should your HMP-based solution connect to the TDM network? • Add a TDM telephony card • Gateway • Key considerations • What are the implications for my solution? • Will it allow me to take full advantage of the benefits of HMP? • What flexibility will it afford me?

  17. Agenda • What is host media processing (HMP)? • HMP in a mixed TDM/IP environment • The choice between DSP-based and host-based media processing • The future of HMP • Summary

  18. Deployment choice – application

  19. Deployment choice – application

  20. Deployment choice – server

  21. Agenda • What is host media processing (HMP)? • HMP in a mixed TDM/IP environment • The choice between DSP-based and host-based media processing • The future of HMP • Summary

  22. The future of HMP • Performance • Resilience • Distributed systems • Hyperconferencing • Wideband and stereo codecs • 3D voice • Video • Greater flexibility – architecture

  23. Resilience • Link protection • Server protection • Control application protection

  24. Distributed architecture Software, distributed amongst several servers, can act as one solution Contact centre solution

  25. Questions

  26. Summary • HMP is viable • Flexibility • Cost efficiencies • For today’s mixed TDM/IP market • Use a gateway and leverage the advantages an HMP-based solution can bring • Integrate into existing card-based solutions • Hardware versus software – it is a deployment choice • The future holds some exciting developments for host-based media processing
