This is a two-part post – Part 1 (this post) introduces the challenges of traditional WAN’s and Part 2 describes Nuage Networks SD-WAN solution.

Today’s applications should not be hindered by underlying network issues or a poorly designed WAN. The business requires designers to find a better way to manage the WAN by adding intelligence with improved flow management, visibility, and control.
