SAME DSP-Engine Network Architecture

Here are the various building blocks required to create a STAGE / SAME DSP-Engine system and how they are interconnected. This network diagram will have to be adapted to your actual network architecture.

See also chapter Network Considerations.

Typical SAME DSP-Engine Network Architecture

A typical SAME DSP-Engine system is built using:

• 1 × STAGE hosted on a COTS server.

• 3 × SAME DSP Engines hosted on COTS servers.

• 2 × Network switches to create an SMPTE ST 2022-7 network. These switches are PTP enabled to ensure that audio is properly synchronized throughout the network.

• 1 × Network switch to create a management network. This is used for:

  • Device configuration and maintenance.

  • Operation and control.

• PCs for configuration and system operation.

• 1 × NMOS Registry for device discovery and management.

• NMOS audio interface devices as required to locally connect analog audio inputs and outputs to microphones, speakers, and external audio processors / legacy equipment.

• Non-NMOS AES67 Audio Interface devices as required to locally connect analog audio inputs and outputs to microphones, speakers, and external audio processors / legacy equipment. In STAGE, these devices are called unmanaged hosts, as STAGE is unable to configure or control them.

Enabling network protocols such as DHCP, DNS-SD, and mDNS can greatly help with system setup and NMOS device discovery.
