Will SonicOS plan to support SD-WAN Forward Error Correction(FEC)

Have known many SD-WAN vendors already support FEC.

Wish SonicOS will consider to support FEC.



Forward Error Correction (FEC) is a mechanism to recover lost packets on a link by sending extra “parity” packets for every group (N) of packets.

Forward Error Correction (FEC) is a technology that is well known for its ability to correct bit errors at the

physical layer. However, this technology can also be adapted to operate on packets at the network layer to improve

application performance across WANs that have high-loss characteristics. With packet-level FEC, network equipment

can reconstitute lost packets at the far end of a WAN link, avoiding delays that come with multiple round-trips

retransmissions. This enables WANs to easily recover from packet loss due to a variety of network layer conditions,

such as queue overflows and constrained bandwidth links. With packet-level FEC, enterprises commonly see significant

improvements in application performance — up to a 10-fold performance increase in some WAN environments.


When both endpoints of a VPN tunnel

that use forward error correction (FEC),

the receiving tunnel endpoint can recover lost packets

before the link needs to fail over to a better path.

Thus, FEC at the network level allows you to maintain

a high-quality application experience in your SD-WAN.

FEC is especially helpful for applications that are sensitive to packet loss,

such as voice and video streaming.

  • Hello @TomChou,

    This is actually a wonderful suggestion. I could not find any existing RFE for this specific feature.

    I would suggest reaching out to your Sales representative and have them file this.

    Thanks!

    Unfortunately I don't know how to find a sales representative to file a RFE.

    So I posted this idea here, could you help on this? or anyone here can help to file a RFE?

  • @TomChou,

    Let me check internally on this matter. Thanks again!
