MTBF, MTTR and SLAs, oh my

Continuing our look into myths of why enterprises "need" MPLS. Today we'll consider two more: "The MTBF and MTTR of broadband connections are too high, so even if they are lower cost and higher bandwidth, I can't afford to use them."...

You can’t be too rich, too thin, or have too much Internet bandwidth

As we move into the era of the cloud, and further into the era of BYOD and the explosion of personal/consumer use of the Internet as a fundamental expectation of individual workers and their devices, having much more bandwidth at...
