Problems with application and network performance on the WAN and Internet links are caused by many and varied issues – congestion, latency, protocol design, sudden bursts of disruptive traffic – all contribute. New factors make the calculus even more complicated: social networking, BYOD, cloud applications, growing video content, even IPv6 traffic growing in the shadows. It’s tempting to respond to these problems by jumping to a single set of technologies that fix certain aspects of performance. We recommend, instead, that you take advantage of Blue Coat expertise and technology to take the four simple steps described in this paper.
