Barix Rolls Out Multicast Routing and Tunneling Firmware

Generally, systems integrators and network operators seeking to utilize multicast transport between subnets face challenging situations.

In an effort to address some of these key challenges, Internet protocol (IP) audio and control specialist Barix has rolled out a new solution that will help media companies, businesses and other multi-site network users to route multicast traffic over remote network links.


The new solution is a multicast routing and tunneling firmware that turns its Barionet IP control devices into flexible, multisite multicast routers. This facility enables bandwidth-efficient, multicast delivery of traffic over the public Internet to remote locations.

The multicast method of data distribution, which is now being leveraged by Barix’s latest solution, utilizes special destination addresses to target groups of subscribed devices, and delivers data and streams such as voice (general paging) and audio (background music).

Unlike standard connections where each device needs its own stream, the multicast data distribution requires only a single stream to send the same content to any number of receivers on the same network segment. This minimizes bandwidth and network usage. Multicast delivery is traditionally limited to private, in-house networks as Internet Service Providers block multicast traffic on normal Internet connections.

Precisely, the multicast routing and tunneling firmware forwards multicast IP blocks to remote receiving devices, re-packed as unicast streams. The receiving devices then re-issue the packets as multicast on the destination network, cites a press release.

The new firmware can be deployed across many settings, because its functionality is independent of actual protocols. This feature facilitates the firmware to be used alongside automation, IP audio, video, Voice over Internet Protocol (VoIP), session initiation protocol (SIP) or real-time transport protocol (RTP) streams.

In addition, the entire operation can be monitored over simple network management protocol (SNMP) to have a complete bird’s eye view of system efficiency.

With the help of the multicast feature in the new solution, system integrators can configure Barix IP Audio systems with more flexibility and less labor as streams are concurrently distributed to many nodes using IP multicast delivery.

Consequently, streaming bandwidth requirements are minimized while simplifying the configuration. Subscription protocols are employed so that relevant receivers, such as a Barix Exstreamer IP audio decoder, receive relevant streams, even if they use dynamic, unknown IP addresses.

Johannes G. Rietschel, CEO and founder, Barix AG, said in a statement, “We are effectively bridging multiple multicast groups between multiple sites for general data and our specialty, Audio over IP, preserving network bandwidth and increasing the efficiency of remote communication.”
