Dante Netspander launched in response to demand
Audinate has announced the release of the Dante Netspander in response to requests from consultants and contractors wishing for a solution that can enable them to route synchronised audio across subnets for large-scale solutions.
The manufacturer states that the Dante Netspander allows scalable digital A/V networks to be built without current constraints. One of the ways it does this is by making it possible to deliver tightly synchronised networked audio across subnets in a Layer 3 TCP/IP routed network
Audinate reports that as Ethernet is a Layer 2 protocol, it is limited to implementing flat networks which reportedly makes it difficult to operate and manage as the number of nodes increases. Layer 3 TCP/IP networking was introduced to provide scalable and manageable networking.
Dante is a layer 3 audio networking technology, and the manufacturer reports that the Dante Netspander allows the full potential of Dante networking over routed networks. Using Layer 3 routers, large networks can be partitioned into subnets, whilst restricting the broadcast of unnecessary data eliminates network congestion. The Dante Netspander also uses Dante’s ‘zero configuration’ networking capabilities to enable devices in a routed network to be discovered and easily managed.
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.
Dante Netspander will be made available as a software application that runs on target PC platforms specified by Audinate.
