Audinate Spans Audio Across Networks
Audinate, which makes media networking solutions, announced the introduction of Dante Netspander at InfoComm 2011.
Audinate, which makes media networking solutions, announced the introduction of Dante Netspander at InfoComm 2011. According to company officials, Netspander allows scalable digital AV networks to be built without some of the existing network constraints.
For the first time, Audinate says, Dante Netspander makes it possible to deliver synchronized, networked audio across subnets in a Layer 3 TCP/IP routed network. In addition, Netspander uses Dante's zero-configuration networking capabilities to enable devices in a routed network to be discovered and managed. It will be available as a software application that runs on target PC platforms specified by Audinate.
Ethernet is a Layer 2 protocol, limited to implementing flat networks that quickly become difficult to operate and manage as the number of nodes grows. Layer 3 TCP/IP Networking was introduced to provide scalable and manageable networking. Using Layer 3 routers, large networks can be partitioned into subnets and network congestion can be eliminated by restricting the broadcast of unnecessary data. Today's corporate networks are all Layer 3 routed networks, but until now, digital audio networking technologies have been limited to operation on a single Ethernet network or a single subnet of an IP network.
"AV design consultants and contractors have been requesting solutions to route synchronized audio across subnets for large scale enterprise solutions such as campuswide networks, universities, hospitals, theme parks, convention centers, broadcast centers, and other large scale network deployments," said David Myers, chief operating officer of Audinate, in a statement.
Dante currently runs at Layer 3. The emerging Audio Video Bridging (AVB) standard will support either a Layer 3 (IEEE 1733) or Layer 2 (IEEE 1722) transport.While Dante will support both AVB transport versions, the RTP-based Layer 3 transport will be required to route audio across subnets. Company officials said Dante Netspander is scheduled to be available by the end of this year.
