Author Topic: What happens when a device is given higher priority on my DGL-5500?  (Read 2775 times)

How StreamBoost™ handles device priority is important to understand. First, device priority does not over-ride application classification, meaning that prioritizing a device to the top does not mean that ALL applications from that device are classified as the highest in the network. Device priority is important only in the case where there is not enough bandwidth to support the multiple applications of the same classification across multiple machines. This is best described in the following examples:

  • If there are 3 devices trying to play HD video streams (protected application class) where there only is enough bandwidth to support 2 HD video streams, then the highest 2 priority devices will have their bandwidth protected to enable proper streaming performance. The lowest priority device will play, but compete with other traffic in the “best efforts” classification. The StreamBoost™ goal is to maximize the number of devices that can have excellent experiences with the given bandwidth, rather than a “fair share” scheme that will likely result in all associated devices having a compromised experience.
  • If the top priority device is starting a data download (i.e. updates, media downloads), this traffic will be shaped to not interrupt the performance for streaming and/or real-time traffic on any other device. Again, the goal of StreamBoost™ is to guarantee an excellent experience for streaming and real-time applications.
