    Short story, I had an exam for a new job which was basically all around the SD-WAN principles and applications, benefits, etc. I had a week off to study and I tried to find the best videos I could on RUclips as SDWAN was not really around when I was in uni years ago. I ended up finding your videos Steve and I watched the different parts maybe 10times, and I must say after watching couple other RUclipsrs that yours were the most well, easily explained and also detailed. I said to myself, well if I do pass this exam, I am defenitly coming back here to thank you and ofc I did get the job. I am now starting a new adventure after 5 years in a NOC, to move on into a more specialized area where I will be proposing buisness network solutions to our customers.
    thanks again
    and sorry for my english it is not my main language

      Hello, Thanks for the recommendation. I can't do that directly in these videos. First, it would not be fair to the SD-WAN providers. The providers have differences, and labeling them strengths or weaknesses may not be entirely accurate. Second, that might be considered proprietary information by my employer. If you want to understand the differences between providers because you are considering purchasing a solution, please get in contact with me. We can have our product team assist you with that understanding. There is no charge for our consulting, so it will not cost you anything to engage us. All the best. Steve

    How can SD-WAN provide guarantee latency like what MPLS line can? Since SD-WAN is using your existing leased lines, doesn't the latency tie to what leased line the SD-WAN is using? For example, SD-WAN cannot improve an existing leased line's high latency connection to India branch office.

    • @steve_murphy1
      @steve_murphy1  3 года назад +5

      Thanks for your comment. SD-WAN cannot fix the middle mile. But when using multiple network connections, SD-WAN can dynamically pick the lowest latency path. If you have applications that require low latency, SD-WAN can support an MPLS or point to point network and optimize your application performance while minimizing the spend on the low-latency network. Lastly, several SD-WAN providers have constructed private middle-mile networks to accelerate traffic over longer distances. With a private middle mile, you have a non-QOS hop-on (usually under 15ms) and then MPLS-like QOS to your destination. If your destination is not a cloud service, then you'd have a non-QOS hop-off as well. Does that answer your question?

Why are so many people saying it is going to "replace" MPLS rather than work on top of it?

      Hello and thank you for your question. The basic reason we use SD-WAN, versus other wide area networking technologies such as MPLS or VPN is that SD-WAN is intelligent in manipulating the applications placed on the network and improves the performance of the applications on the network. It improves user experience for mission critical applications in the data center and in the cloud. I hope that helps. Best, Steve

    • @steve_murphy1
      @steve_murphy1  3 года назад +6

      Hello! SD WAN is designed to replace MPLS in most use cases. SD WAN is a VPN-based technology that uses the public internet. The biggest objection to SD WAN versus MPLS is the lack of finite quality of service commitments. Most organizations can use the public internet, even without guarantees around loss, latency and jitter. If you do need quality of service, there are some SD WAN service providers that have a middle-mile private network that can give you the MPLS experience. Best, Steve

    • @steve_murphy1
      @steve_murphy1  Год назад

      Thanks for your question. Both are very mature platforms. Cisco (formerly Viptela) has the advantage of increasingly strong integration with the broader Cisco stack. Versa, I believe, will struggle to keep up in the development cycle and be a player in the SASE space. Versa has focused its distribution model on service providers. This may hurt them as service providers may not push them as hard to develop additional capabilities - they are further removed from the voice of the customer than other solutions. Best, Steve

    • @steve_murphy1
      @steve_murphy1  Год назад +1

      Hello Angel, SD-WAN is software defined, but most SD-WAN providers come from an edge appliance background, so they have built their software into their edge appliance strategy. Since much of the application routing and prioritization decision making includes the access available at a location, traffic direction at the edge is desired. White box options are available from some providers. Other have just a small/light appliance that does route selectin and encryption and all the processing is in the cloud. Hope that helps. Please let me know if you need assistance. Best, Steve

    What about the CoS that MPLS provides from layer 2?

    • @steve_murphy1
      @steve_murphy1  2 года назад

      SD-WAN has a similar function in prioritizing traffic. It's class of service (CoS) at the edge. Because SD-WAN normally uses the internet, CoS is not applied in transit. Optimal route selection helps, but there are no guarantees. If transit QoS is required, using an SD-WAN provider that has a private backbone can solve for that. Thanks for leaving a comment!
