I graduated from the University of Sheffield in 1991 with BEng in Electronics, Control and Systems Engineering.
Some years later I became a Chartered Engineer.

For the bulk of my career I worked for Nortel Networks, until the telecomms industry bubble burst in 2004.  Still, I walked straight in to another job with a higher salary and got a nice redundancy cheque.

Whilst at Nortel I became something of an expert in Internet routing protocols, particularly  Integrated IS-IS and multiprotocol routing.  I also filed a few patents though I don't suppose any of them were actually granted.  Some of my work also ended up in an ITU-T standard.

Some examples of my work:-
RFC 3147
TLV for Experimental Use
RFC 3147 got adopted by the ITU-T and has been implemented by the major optical networking companies and by Cisco.
It's early days for the experimental TLV.

Lastly I found out afterwards that I had become an expert in highly resilient data networking without realising it.

Now I am working for a mobile phone company looking after the resilience of their data network and services.
I have also been debugging the OSI stack in NetBSD when I get the odd moment spare.
