Bandwidth Considerations and Optimization

Ensuring sufficient network bandwidth and overall performance is a critical step in preparing for a successful vis|ability deployment. Before commissioning begins, the network must be validated to support the expected volume of video streams, data traffic, and system communication.

This is especially important in environments where multiple high-resolution video sources are being distributed across one or more Display Nodes.

vis|ability relies on the real-time delivery and decoding of video streams and data across the network. Insufficient bandwidth or network congestion can result in:

• Dropped or unavailable video streams
• Increased latency in content delivery
• Degraded system performance
• Inconsistent user experience

Validating bandwidth ahead of deployment ensures that the system can operate reliably under expected load conditions.

Display Nodes are typically the most bandwidth-intensive components in a visability deployment, particularly in video-heavy environments.

Typical Performance Expectations

• A standard Display Node can decode up to:
  • 24 simultaneous IP video streams
  • At 1920×1080 resolution, 30fps, H.264
• Smaller form factor systems (SFF/MFF) may support:
  • Approximately 4 simultaneous IP streams under similar conditions

Actual performance may vary depending on system configuration, stream quality, and network conditions.

When validating bandwidth, it is important to consider both per-device throughput and overall network capacity.

Key Areas to Review

• Available bandwidth to each Display Node
• Aggregate bandwidth across switches and uplinks
• Number of concurrent video streams
• Resolution and bitrate of source content
• Other network traffic sharing the same infrastructure

In larger or video-intensive deployments, higher-capacity uplinks (such as 10Gb) may be required to ensure consistent performance.

For most vis|ability components:

• Gigabit Ethernet is sufficient for standard connectivity
• However, sustained and reliable throughput is critical

As a general guideline:

• Each Display Node should have access to dedicated, consistent bandwidth appropriate for its workload
• Network congestion or shared links should be minimized where possible

In addition to network bandwidth, overall system performance is influenced by how video streams are decoded and processed.

vis|ability utilizes GPU-accelerated decoding to optimize performance, leveraging technologies such as:

• Hardware acceleration via AMD or NVIDIA GPUs
• Efficient video decoding pipelines (e.g., H.264 optimization)

Proper system configuration — including graphics drivers — plays a role in achieving expected performance levels.

Consider segmenting high-bandwidth devices (like Display Nodes) onto separate switch interfaces or VLANs to minimize congestion. Coordinate with IT teams to validate switch backplane and uplink capacity in relation to the expected load.

Avoid daisy-chained or shared switch configurations. Each Display Node should be connected directly to a high-performance access switch, ideally managed by IT staff with visibility into real-time traffic metrics.
