As promised, here I am reporting back on Project IST-Daidalos which had it’s final audit in the beginning of the month.

First things first, here is the video of the project describing what the project is about:

On a personal note I would like to say that I’ve been involved in this project for as long as I’ve started my research career, which is just a bit over 5 years ago. This project enabled me to meet people in most parts of Europe, to know their way of doing research and of course to learn from them and with them. Strangely enough: I was getting sick of this project

What’s with Cisco and the Kusec?

November 21, 2007 English

This week my ARA (Advanced Networks class) lab students got the chance to work with some recent equipment acquired by the department. The equipment consists of several enterprise grade CISCO networks wireless units (Access Points and Network cards) that most of them will eventually deploy in their future careers, and have during these labs classes the chance to a have a first contact with.

The curiosity here lies on the fact that Beacon Periods in CISCO equipments do not use “standard” time units.. they use something called Kusec. What ?! a Kilo Micro Second ? In my days (and guess wikipedia days…) Kilo meant 10³ and Micro meant 10⁻⁶ which would mean 10^-3 or good old Milli. So where from does Kusec comes from? Kusec equals (according to CISCO) 1024 microseconds… hmmm shouldn’t it be then a Kibi Micro Second ? and therefore Kiusec ? And whats wrong with miliseconds ? All other vendors have the Beacon Periods configured in milliseconds…
