Network Considerations
Network connectivity is required to allow the installed Riedel software to communicate with devices, to provide the user interface for operators and engineers, and to provide northbound APIs to other systems communicating with the corresponding installed Riedel software.
Network Data Types
In an intercom/broadcast network, there are generally two categories of data that are transmitted in IP networks:
Management data that consists of the signalling, control, and health information communicated with connected endpoint devices. This data is used by a control network to operate these devices.
Media data that consists of high-bandwidth SMPTE ST 2110 audio, video, and ancillary flows.
Interface Types
Management Interface
Network interfaces that are used for management purposes are usually connected to a control network that connects the management interfaces of other endpoint devices in the system. In the simplest case, the server on which the Riedel software is hosted is connected to a management network with a single network interface.
Ensure that Network Interface used for the management network has its gateway set.
Using Multiple Management Interfaces
In some scenarios, it may be necessary for network segmentation to establish a network connection with multiple networks from the same Riedel software instance. For this purpose, multiple network interfaces must be configured at the Linux host level.
If you are using multiple network interfaces, make sure at least one of them has its gateway set and it is always available.
Media Interface(s)
In-band vs. Out-of-Band Management
Most devices have two or more network interfaces that are connected to separate network segments (switches). One network interface is used for management purposes (out-of-band management) by connecting it to the management network segment. The remaining network interfaces are used for media streaming. The network interfaces of the nodes with the installed Riedel software are connected to the management network segment to ensure connectivity with the management interface of all device endpoints.
Some devices may not have a separate network interface for management purposes. In this case, the management functionality is combined into the media interface(s) (in-band management). In this scenario, the management interfaces of the nodes with the installed Riedel software must have connectivity to the media interfaces of the device (e.g. through an appropriate routing set up in the network itself), or the host must be connected to these network segments via a dedicated network interface.
