What is SD-WAN?

What is SD-WAN? SD-WAN is software defined wide area network. Let's talk a little bit more about what it is and who can use it and the players involved.

Love to hear more about it seriously considering getting rid of the multiple Cisco VPN tunnel single point of failure design we have right now.

We use Silver Peak appliances for SDWAN, which was bought by Aruba Networks:)

Thanks. Pretty good exclamation.
Maybe explain the separation of data plane and control plane

its dm-vpn with policy based routing and failover if ya got two isps

What gets me is low this is hyped but when it comes down to it, you still need physical links and that is where the problem happens.
We have clients that may have MPLS by a major provider (and they aren't even the actual circuit provider) and local internet with DMVPN to interconnect sites. Sure, perhaps you might offload handling the router/firewall equipment and equipment yourself but you still are at the mercy of the circuit reliability and given bandwidth, probably the same ones you already have.
Or am I missing something?

I am still not clear on what SD-WAN is. Is it basically QoS for the Internet? We have been enabling and managing QoS at the local router to prioritize certain network traffic entering and exiting our LANs that requires low latency such as 2-way real-time communication like video chats and VoIP. So is SD-WAN the QoS for the WAN which is the Internet? If so, the various industrial-strength routers that route Internet traffic need to prioritize certain traffics to match that of the QoS settings in the routers that sit between the WAN and LAN. Cisco definitely has to be on board with this for SD-WAN to be a reality since its routers are found in both the WAN and LAN sides.

Hey thanks for taking the time to do a high level overview next time move yourself down to the right hand corner so we can read what you typed out.
