Video UDP Traffic


I am interested in using a peplink modem to bond multiple 3G signals in the UK to transport a video stream.


At the source site

  • Remote site with access to different service providers e.g. Orange, O2, Three and Vodaphone.
  • Install one modem (4 modems in total) from each service provider in a peplink mobile router.
  • Connect to the router a Video encoder, configured to point to Video decoder with a single IP address on the destination site

At the destination site

  • Destination site with access to internet connection greater than 5Mbs
  • Peplink router connected to the internet and connected to a video decoder
  • Video Decoder with single IP address

My understanding is that the peplink mobile router will establish 4 VPN connections, one across each of the internet connections at the remote site to the Peplink router at the destination site - is this correct?

What I want to be able to do is to distribute the UDP traffic from the encoder across each of the 3G modems, taking advantage of the bandwidth available on each of the connections. For example if each connection provides 512kbs, it would be theoretically possible to pass a 2Mbs stream of video from the remote site to the destination site, splitting the packets between the different connections using the peplink router?

If this is possible using the peplink routers, would the routers also compensate for different connection speeds and latencies on each connection e.g. if one connection provided 256kbs and another 512kbs, the network traffic would be balanced accordingly?

Many thanks


Hi James,

Your understanding is correct. The MAX mobile router will establish a secure VPN connection to Peplink Balance at the destination site. bonding the upstream (and downstream too) bandwidth available on all four 3G modems. Your application is actually common among our other customers taking advantage of our bandwidth bonding technology.

Bonding efficiency is around 90% hence if each of your 3G connections gives us about 512kbps of upstream bonding four of then we should have around 1.8Mbps. And yes Peplink will compensate for different bandwidth and latencies on each connection. Please be reminded while our bonding algorithms intelligently detects connection status of each underlying connection and route accordingly for optimal result, actual bonding performance will depend on the real-time status of all underlying connections that Peplink has limited control of e.g. effective bandwidth, latency and packet loss.

Feel free to contact Peplink sales to move this discussion further.


Hey Kurt,

Thanks for your clarification - much appreciated.
