cloud computing is so noughties

now we are in the pre-teen era of the 21st century,
we should concentrate on Blue Sky research...

no more sensor nets (wastes batteries - very unsistainably)

no more MANETs (dont work)

no more opportunistic or p2p networks (capitalism is so much better than anarchy)

no more economics + computing (computing is dismal enough without addign an entire dismal other "science" to it)

no more green computing (the answer is 1 bit - turn it off:)

Digital Communications II Progress by 13.11.200

Friday 13th - we havn't got quite as far as I thought - so we've done Scheduling (and Queue Management), and made a start on Switching.

Next week, must finish switching AND do contention networks.

Digital Communications II Progress by 6.11.2009

This week, should have finished
error control (sequence numbers, retransmit/rtt timer estimation)
and
flow control (at least intro to open&closed loop)

as with last week (routing)
these topics come up in exam questions frequently.

This week I'm doing routing - I've updated the material so please check the new version of slides - DAR + DV/LS is a bit tidier (I hope) but if you spot errata, let me know!

lots of stuff for supervisions and exam questions now.
