What are the Hololight Stream Network Recommendations?
Change Ports and set bandwith for your Network
You can modify server-side settings for your project by navigating to the Hololight Stream section. This area allows you to customize various parameters related to your connection process.
Signaling port and Port range
The Signaling port number must be between 1024 and 65535. If unset, the port defaults to 9999.
The port range allows the user to specify the ports used for the running connection. The range must be between 1024 and 65535. You can set a single port by setting the minimum and maximum for the range as the same value. By default the port is set to 50100. This port can overlap with the signalling port.
Encoder bandwidth
Specifies the maximum encoder bit rate. A higher value will result in a better image quality but at the cost of network performance. The recommended range is between 10 Mbps – 100 Mbps. If the value is set to -1, the bit rate will take its value from the settings in the connected client
Bandwidth multiuser
At this point in time, Hololight Stream allows one device to connect to one application instance. In principle, applications like Unity3D or Unreal Engine, are usually allocating a maximum of one GPU per application instance therefore, one user connects to one application instance which runs on one GPU.
Because together with GPU, CPU and RAM can affect the overall application experience, depending on the data complexity, it is today possible, to allocate multiple application instances to a single GPU. This will offer the first possibility to scale usage across infrastructure. The second currently supported scaling option is the usage of shared GPU (vGPU). This way, once again, we could aggregate application instances in virtualized infrastructures, making possible to grow the number of concurrent sessions.
Last, in case of applications supporting multiuser experiences, at this point in time, the previously mentioned points will be valid if the application takes care to synchronize the user experiences (i.e., avatars, camera position, alignments, etc.)
Network Requirements
| Minimum | Recommended | |
| Network | Wi-Fi 5Ghz | Wi-Fi 5Ghz |
| Bandwith | 20 Mbit | 40 Mbit |
| Round Trip Time | – | max. 50 ms |
Latency
For Hololight Stream, as per any other streaming application, the lower the latency, the smoother the experience. At this point in time, Hololight Stream can in average offer a smooth experience between 50 and 100 milliseconds of latency.Latency is as important as network fragmentation and Quality of Signal. Frequent data retransmissions will negatively affect user experience despite low latency.
