Radisys Highlights Importance of Transcoding, Media Server Control and Virtualization in WebRTC Environments


As organizations shift toward all IP-based networks, the variety of audio and video codecs in networks is growing. Transcoding gateways convert one codec to another for proper signaling interworking and security, which is essential as the industry needs optimized architecture for IP to IP transcoding.

Grant Henderson, vice president, Corporate Business Development & IT, Radisys, gave a keynote presentation last week at WebRTC Conference & Expo in Santa Clara that emphasized the importance of transcoding in an IP and WebRTC world.

He cited a Disruptive Analysis graphic on eight different WebRTC use cases:

Browser-to-browser or Web app communications

Browser-to-telco

Browser-to-telco CS/PSTN

Browser-to-UC or IP-PBX

Browser-to-Web server

Browser-to-contact center

Browser/app conferencing

Verticals

Seven of these eight use cases – not browser-to-browser or Web app communications -- need media processing. In order for WebRTC media processing to happen, the technology needs interworking capabilities with SIP endpoints and WebRTC gateways will need scalable transcoding.

After the keynote, I caught up with Ray Adensamer, senior product marketing manager at Radisys, to discuss the growth of WebRTC and how Radisys plans to serve industry demands and needs.

In terms of the WebRTC industry moving forward, Adensamer emphasizes the need for companies to figure out how to monetize the technology. It needs a combination of proper marketing muscle to support these services, added value to vertical applications and good quality communications to continue to grow. He is excited about the conferencing potential of WebRTC in the context of specific vertical applications, and how it opens up that functionality to app developers, not just a few vendors that previously dominated the space.

Radisys has spent the last 10 years in the world of IMS and next-generation networks. Its goal is to position those technologies into the WebRTC space and make SIP more broadly applicable, since the industry will require centralized media.

“We’ve proven how to deliver reliability and scalability,” Adensamer said. “VoIP audio conferencing providers use our technology in their networks, and we’re bringing that knowledge of making it scalable to WebRTC.”

The company offers hardware, software and virtualization all supported by its MPX Operating Software, and says although many media processing solutions today are software only, there is still a role for hardware routers and switches in the network. In the future, it hopes to add more Web-friendly APIs and be able to control media processing functions.

The MPX-OS is the software foundation for Radisys media processing products and solutions, supporting real-time multimedia processing requirements for IMS MRF, OTT cloud and WeBRTC communication services.

Radisys is supplying virtualized, scalable VP8 to H.264 transcoding solutions for WebRTC gateway products. It interconnects WebRTC and IMS services and endpoints. The gateways are in pilot deployments at many larger service providers.
