SD-WAN for enlightened
Hi, I'm not sure if the buzzword SD-WAN is used to compensate for another buzzword that got over-utilized (SDN) or it is a true 'new and improved' way of doing things that has some innovation into it. I heard different explanation from different vendors: 1) appliances (+ controller) placed in-line to put traffic in tunnels based on policy, with some DPI and traffic tagging...(to do performance/policy based routing) over an expensive link (MPLS) and a cheap one (broadband) with some 'firewall-like' filtering capabilities. 2) same as above, with a flavor of 'machine learning' to find a pattern for traffic to optimize utilization. 3) a controller that instantiates and tears down tunnels from 'classic routers' based on external policies and Network based features to do performance based routing over an expensive link (MPLS) and a cheap one (broadband) with encryption. Is the above a decent high-level summary? Has anyone tried any of these solutions, any general feedback ? Cheers, Kim

Re: Facebook more specific via Level3 ?
Hi, got the same from Kiev, Ukraine: dig fbcdn.com fbcdn.com. 300 IN A 31.13.74.1 which is slow and routed through USA and dig fbcdn.com @8.8.8.8 fbcdn.com. 299 IN A 31.13.93.3 which is fast and routed through Germany Same is for IPv6. Is there any solutions without dirty hacks?
