MPLS is dead, Long live MPLS

The initial hype of SD-WAN claimed that MPLS was dead as SD-WAN was going to remove all need for SLA based circuits. Now that we’re several years in and have some experience under our collective belts, we take a look at whether or not the original hype was correct and what real world customers are doing when it comes to selecting circuits for their SD-WAN networks.

    hello,
    for the issue mentioned at around 5:34
    how can DS-WAN clear under laying circuit issues like packet loss or jitter? It’s obvious that I am very new to this concept, but how do you solve such things, really? I mean how does it deal with packet loss for a service like voice???
    Regards,

      Yanna,

      It isn’t so much that SD-WAN actually corrects those errors, it’s that it sees them in real time and routes around them. If you have two links you can set your voice traffic to prefer one of them but flip to the other as soon as the primary link doesn’t meet an acceptable service level. It gets more nuanced when you start talking about forward error correction, which is when you send the traffic down both links, significantly reducing the odds of any single packet being lost due to errors. I hope this helps.

    Hi Jordan,
    it helps, thanks. In the meantime I did a little research on my own, found about the same things .
