Available from firmware version 8.0 for Peplink routers with a SpeedFusion WAN Smoothing license.
Introduction
When using multicast applications on lossy WAN connections the performance can suffer.
To overcome these problems Peplink introduced WAN smoothing, but WAN smoothing has an overhead of at least 50%.
This is not always desirable when there isn’t enough bandwidth available.
Peplink has therefore introduced Forward Error Correction in Firmware 8.0
FEC is a cousin of WAN smoothing but it consumes less data.
It is useful for bandwidth sensitive applications such as mobile streaming.
When to use:
Forward Error Correction
Bandwidth sensitive 1-way communications like live TV and video streaming. WAN Smoothing
Latency sensitive 2-way communications such as VoIP or Video Conferencing.
FEC definition
Forward error correction (FEC) is a digital signal processing technique used to enhance data reliability. It does this by introducing redundant data, called error correcting code, prior to data transmission or storage. FEC provides the receiver with the ability to correct errors without a reverse channel to request the retransmission of data. It is required that the peer router is using Firmware 8.0.0 and above.
Configuring your Peplink router
In the web admin interface go to Network > Speedfusion on your Balance router or Advanced > SpeedFusion on your MAX router.
Select a “New Profile” or open an existing PepVPN profile.
Select the option of choice on the Forward Error Correction drop-down list.
Save and Apply the changes
Very impressive feature!
With FEC set to “High” moving UDP/RTP over dual bonded LTE with almost no errors (!!)
Without FEC, video looks like slideshow, which is expected when moving UDP/RTP over public networks.
Wow! Thank you!!
Hi. I understood this is great feature for Bandwidth sensitive 1-way communications, so I suppose this is not usefull for Remote Desktop/Citrix communications, am I right ? Thank you.
Nope you’re wrong. FEC is useful for any real-time application traffic like a citrix desktop session.
Most people think about FEC for broadcast video as that#s where you see it most often, but any application that is jitter or packet loss sensitive would benefit from FEC.
This is rather strange. Can you please screenshot the “Profile Option” page and paste it here ? I checked all the devices in my labs, i can find the option.
Beside that, can you try different Web browser and see whether you can see the option ?
my Apologies, I do not understand what you are saying…
Are you telling me that my Device Max-transit-duo has a compatibility issue with the fusionhub?
My Device Max-transit-duo is not capable to perform FEC ?
please guide me how to fix it. thank you
