The patent describes a method for telecommunications services providers to deliver audio, video and multimedia services through an Internet relay provided by a session border controller (SBC) without routing packets through a network device called a TURN server. The process yields faster connections, a better user experience, greater scalability, improved reliability and greater protection against denial-of-service attacks.
The U.S. Patent and Trademark Office granted Sansay patent No. 8601144 B1 on
"Sansay's WebSBC solves the problem of traversing restricted firewalls by allowing ICE media-relay candidates to be created automatically by the web application without forcing the clients to use a TURN server," Ryner said. "The REST based auto-relay creation results in faster call-setup times by eliminating the need for the client to locate, request and authenticate itself to a network-based TURN server. The technology also improves the media-handling scalability, while reducing the threat of denial-of-service attacks that otherwise exist in typical TURN server deployments."
The company is now shipping its WebSBCs that incorporate the patented process, which enables providers of "over-the-top" (OTT) services to offer new functions and features, such as media decryption, forking, recording and transcoding. Ryner said Sansay's WebSBC also provides a control point for performing Quality of Service analysis and troubleshooting.
