The Video Services Forum (VSF) has announced it has incorporated a relay function into the Reliable Internet Streaming Transport (RIST) protocol to address the issue of firewall traversal for RIST devices.
The RIST Relay provides a connection service to RIST devices using the RIST Advanced Profile, said the organisation.
RIST devices connect to the RIST Relay as a rendezvous point, and the RIST Relay either facilitates a direct connection between the RIST devices, or relays the traffic between them. The RIST Relay is also capable of supporting group operation (many-to-many communication).
“The RIST Relay function allows devices to connect simply and securely across firewalls, without needing to open ports in advance,” said Adi Rozenberg, CTO and co-founder, Alvalinks and RIST Forum director.
“Using a proxy device that is external to the organization and a SIP-like mechanism to connect peers and organisations, RIST Relay massively simplifies connectivity, solving many real-life broadcast problems. The RIST Relay is an exciting development that brings much-needed functionality to the market, enabling many new user applications.”
