Rant: Screen Reading – Comparing Windows and MAC

Greg Ferro — Thu, 29 Dec 2011 14:13:20 +0000

DSCP QoS Over MPLS Thoughts

John McManus — Mon, 06 Sep 2010 22:00:52 +0000

I have been working on the edge of MPLS networks for several years and had a basic understating of DSCP QoS values that I was sending into the cloud and expecting them to pop onto the LAN at the other side the same. The QoS queues on the CE's were already setup and I have had no reason to change then until recently for a new VOIP project; this and my studying for CCIE SP written has prompted me to understand DSCP in depth but also understand how this LAN QoS maps to MPLS QoS.

Musing: On Permananent and Ephemeral Knowledge and Exam Study

Greg Ferro — Thu, 13 May 2010 20:45:38 +0000

Like many tech-workers, we need to ingest vast quantities of knowledge to get started in our jobs. Without that knowledge, there is no working in our business. What is unique, however, is that we continue to ingest knowledge for the remainder of our careers - often consuming large portions of our personal time and energy. Worse we even get tested on it by sitting formal examinations. How can we manage this process to be more effective ?
