Obama’s Speech: A Bandwidth Hog? Barack Obama’s speech at the convention is available for download from the official convention site in what they term to be “high definition” video. And admittedly the video quality (making no value judgements about the rhetorical content) looks fantastic. But how much bandwidth is it taking up if someone were [...]

Scalability isn’t just about numbers
Scalability is one of the more overused terms in networking – which makes it hard to explain why it’s important. Well, I mean, beyond the main concept of: “More scalability means you can hook up more computers to it!” True, how big the deployment is probably the best way to objectively prove scalability – for [...]
John Dvorak – baiting the cloud
Saying that your business should never, never, never use cloud-based applications instead of desktop or network/server based ones is about as ridiculous as saying that cloud-based applications will eventually replace IT completely. With an article that begins with “Cloud computing apps are for suckers. If there is an alternative that runs locally on your own [...]
Convention season’s impact on network performance.
I wanted to name this post “Things to view in Denver: Talking heads” but no one around the office got the reference. Well, if you were worried that Obama’s VP announcement would overwhelm your network, you were spared. The announcement came in the middle of the night – 3 a.m., in fact – on a [...]
Going mad with power… consumption in the data center.
Cisco has put up a new video in their “Seminar and Webcast Series” talking about “Energy Efficiency in the Data Center.” It may be produced by Cisco but the key points are pretty much vendor-neutral – starting with the idea that “Green” computing is a political/PR buzzword, and the way enterprises should look at the [...]
Cisco’s WAAS and the Olympics
I can’t believe I missed this the first time around. I was so focused on how the online Olympic video was getting through the last mile, that I completely forgot to ask: How the heck are they getting it from Beijing to the U.S.? Douglas Gourlay at Cisco has been blogging about how NBC’s been [...]
A Special Comment
And now, some additional notes. Though Network Performance Daily is the company blog of NetQoS – it should be considered that this video and this posting are my own sole opinion as editor of the blog, and does not necessarily represent the opinions of NetQoS, their management, employees, or customers. I know that many [...]
Why the Olympics stay online – because fewer people than you think are watching.
While we’ve talked quite a bit about what impact the Olympics may have on an enterprise network’s performance, we haven’t talked much about the performance of the NBC site hosting the live streaming of the Olympics. According to Jason Perlow at ZDNet, Limelight networks (which hosts the streaming videos) deployed the videos by going to [...]
Death by checkboxes – Ben runs the Voodoo down.
By Ben Erwin Product Manager, NetQoS. After watching Jamaica destroy the competition in the male and female 100M races at the Olympics, I was reminded that I still have a crystal ball on loan from Miss Cleo. Needless to say, it was time to take another look into the future of network performance management. After [...]
You down with FCC? Yeah, you know me.
Jim Metzler and Steve Taylor have another insightful article up at Network World – this one on the effects of the FCC ruling against Comcast over their BitTorrent blocking using deep packet inspection technologies. Perhaps some of the best news for corporate network managers is that this is proof that equipment designed for DPI actually [...]
Whose OC3 Line Is It Anyway?
A number of East Coast based customers of World of Warcraft have been experiencing connection delays and uncomfortable lag – and no one seems to know exactly where the problem is. The New York Post says that Blizzard is blaming Time Warner Cable is for the problem: “The only commonality between all the players experiencing [...]

Mind the skills gap.
Network performance is just as difficult – and just as important – as network security, but security is “sexier.” It brings to mind ideas of James Bond’s villain Boris yelling, “I am inwincible!” But, if you’ve got an IT staff that knows a lot about security but nothing about latency, you can guess how well [...]
