Network And Device Requirements For Highfive


This article lists all requirements you'll need to use Highfive.






  • HTTP TCP port 80 access to the internet.
  • HTTPS TCP port 443 access to the internet.
  • Outbound UDP port 5005.  Replies sent to a flow on port 5005 must be routed back to the Highfive client through any firewalls and NATs. 


As with any real-time web conferencing system, Highfive attempts to compensate and adapt to network conditions and glitches.  However, you can help ensure best results by being aware of what can help the most. Video and audio are sensitive to 4 fundamental metrics of network health: available bandwidth, packet loss, latency, and jitter.


You can test your network connection using the steps outlined in this article before you start using Highfive.


Here's what we have at our Highfive offices for the absolute best audio and video quality:

  • Bandwidth: For the most optimal quality, we recommend 2.5 Mbps (uplink) and 4.5 Mbps (downlink) available to each device that will be connecting to a meeting.  Mobile devices require 1Mbps up/down per endpoint (2Mbps up/down recommended). Highfive will adjust call quality based on the amount of bandwidth available.
  • Packet loss: less than 1.0% link loss at the throughput listed above
  • Latency: less than 70 ms one-way latency to the Highfive service (e.g., with a standard deviation less than 30 ms.
  • Jitter: less than 30 ms.


Video quality will suffer if these conditions are not met.  You may see frozen video, low framerate, lower image quality, or higher "lag" especially with respect to the accompanying audio.


On mobile devices, Highfive recommends using Wi-Fi instead of cellular data, if available.


Note: For networks that are more customized, the network optimization steps outlined in this article can be performed to ensure the best experience possible.
