Agenda: Media Enablement Layer and Application Delivery

Changing Media Server Landscape

Media Server = MRF: PowerMedia™ XMS

Application Delivery: Hottest Features

WebRTC: Server Side Media and PowerMedia™ XMS

WebRTC: Use Cases

Scaling: Application delivery and intelligent media brokering


Changing Media Server Landscape

Software-based Media Servers› Decompose application delivery from media processing› Move away from ‘big iron’, desire to utilize COTS hardware› Reduce CAPEX costs

VoLTE› Voice over LTE (IR.92) - HD Voice and AMR-WB› Video over LTE (IR.94) - Video and dynamic adjustment

Virtualization› Media processing moving to the cloud› Movement to Network Function Virtualization (NFV)

WebRTC integration› WebRTC codecs – VP8, VP9, OPUS, iLBC› Interopability with web browsers› Service Evolution of customer products


Media Resource Function (MRF)

PowerMedia XMS

Media Resource Function (MRF)› MRF handles processing and

manipulation of media streams in IMS and VoLTE networks

› Example uses

Media mixing/routing

Tones, DTMF

Conference, IVR

Transcode/Transrate/Transsize

WebRTC anchor PowerMedia™ Media Resource

Broker (MRB)› Provides Reliability and Scalability

Whisper (Coach) Conferencing Feature Highlights

› Connect call parties to multiple conferences

Create sidebar conferences

Create whisper conferences with multiple coaches

Supervisor ‘Barge In’ to main conference

› XMS Architectural Improvement

Previously restricted to one conference connection

› Supported in both REST and MSML

Standard MSML method to create sidebar conferences

Also supported through Dlgc ‘coach’ attribute

› Notes:

Callers can transmit to multiple conferences, but only listen to one conference

Multimedia (A+V) streams can not be split between conferences

Video Transaction Record

Feature Highlights› Join call parties & record audio/video transaction

Joined parties full-duplex

Fork media (half-duplex) into conference for mixing

› Joined video parties see only each other› Recorded file contains mixed conference output

Mixed Audio is summed output of conference

Mixed Video is layout programmed in video conference

› Supported in both REST and MSML

› Notes:

Audio Transaction Record requires 2 XMS Audio licenses

Video Transaction Record requires 3 XMS Video licenses

Multimedia (A+V) streams cannot be split

Lessons Learned:• Applications are viable today when you have end-to-end

control• Leveraging existing infrastructure shortens time-to-market• Assume you will have poor connectivity• Be careful with variable cloud latencies

Incoming SIP rate exceeds supported call rate

Use Case 1 – Congestion Management at Application Server, Web Server, SIP Servers and other Network elements

Incoming Traffic far exceeds capabilities of the individual instance;

Causes service disruption and outage
