The hybrid WAN is an idea that’s been around for decades now. Prior to being an analyst, I worked in corporate IT and I was building Internet VPN links to connect home office workers, small branch offices, or back up connections. Back in the “old days”, a hybrid WAN was definitely the exception and far…

Dear MPLS, We Need to Break Up
/ Nov 12, 2014 10 COMMENTS

Dear MPLS, I’ve considered writing this letter for quite some time.  Fifteen years is a long time together, especially in the technology world. Many would say that this is long overdue.

In a previous entry here on the WAN Speak blog I discussed some of the differences between the LAN and the WAN.  I also pointed out that there are not any fundamentally new WAN technologies under development, and that as a result, IT organizations need to plan for WAN evolution based on the assumption that,…

I’m old enough to remember when an organization could pretty much draw a line around itself and say, “that’s us”.  Sure, suppliers and customers were involved, but as far as IT was concerned, little interaction happened beyond the four walls of the organization itself.

When “East-West” is More than Pacific to Atlantic
/ Oct 12, 2012 0 COMMENTS

When discussing cloud computing, the term “East-West latency” often comes up as users on one coast of the US have found themselves using data centres on the opposite coast – and find that the user experience was not quite as they would wish. The direct distance between San Diego, California on the western seaboard to…

No WAN is an Island
/ Sep 7, 2012 0 COMMENTS

“No man is an island, entire of itself. Each is a piece of the continent, a part of the main.” The timeless metaphor by English poet John Donne provides many applications for reflection. Far from being islands, Wide-area-networks (WANs) actually interconnect islands of technology, such as data centers, branch offices and islands of individual mobile…
