Transform Real-Time Audio
Workflows with Multicast 

Leverage cloudSwXtch to to deliver high-quality, scalable, standards-based audio workflows on-prem or in the cloud.

cloudSwXtch Value Delivered 

Capabilities teams are used to on-prem

  • Low Latency: Near real-time audio delivery with minimal delay, critical for live production environments.

  • Standards-compliant interoperability: Supports AES67 and ST 2110-30 standards-based audio platforms.

  • High Reliability: Consistent audio delivery with robust infrastructure.

Additional workflow benefits from the cloud

  • Scalability: Effortlessly scale audio workflows to meet the demands of global audiences, from small teams to large broadcasts.

  • Remote Collaboration: Deliver audio to distributed teams and audiences worldwide with AWS’s global network.

  • Cost Efficiency: Reduce infrastructure costs by utilizing cloud-based multicast solutions on cloud.

  • Reduced Complexity: Simplifies workflows by eliminating the need for costly on-premises hardware.

  • Flexibility: Supports diverse production needs, from live sports to corporate events.

Real world impact

  • Live Sports Broadcasting: Stream high-quality audio to global audiences with minimal latency for real-time commentary and effects.

  • Radio Production: Support remote production teams with reliable, low-latency audio feeds in the cloud.

  • News Production: Facilitate real-time audio workflows for breaking news and live reports across multiple locations.

  • Corporate Events: Enable seamless audio for virtual or hybrid events, ensuring clear communication across distributed teams.

  • Live Music Events: Deliver immersive audio experiences for virtual concerts with scalable cloud solutions.

Empowering Audio Workflows in the Cloud

Many leading audio communications vendors leverage cloudSwXtch to migrate intercom and other audio applications to the cloud, maintaining real-time performance. By bridging the multicast gap, cloudSwXtch ensures that audio applications remain agile, secure, and cost-efficient in modern cloud architectures.

Example Architecture

01

Intercom clients are distributed globally in venues, outside broadcasting (OB) trucks, and studios.

IP intercom belt packs connect to the Cloud through a virtual intercom platform and cloudSwXtch.

​

To transmit and receive audio over multicast in a hybrid environment, cloudSwXtch Bridge is used to enable multicast joins and leaves between connected nodes. 

02

Signals are transmitted & received between on-prem locations and the cloud.

Completed using an interprise internet connection or public internet.

03

In the cloud, audio feeds are switched to the nodes using standards-based IGMPv2 join requests using cloudSwXtch.

cloudSwXtch is the router appliance that runs on VM instances enabling multicast network overlay. cloudSwXtch also manages the deployment and communication with the xNICs that are integrated into the applications running on VM instances.

04

Multicast transport is facilitated between VM instances on the swXtch network using xNICs are software agents.

Applications running on VM instances are able to send and receive multicast streams through the xNIC, regardless of where the senders or receivers are located. Latency from the venues to the VM instance is around 150 milliseconds (ms). Additionally, cloudSwXtch implements hitless packet merge (SMPTE 2022-7) with the virtual intercom nodes.
