Hi All,

Pleased to announce that we have an external guest speaker- John Day
for the next NRG talk.

He will be talking on " Networking is IPC and Only IPC"

When: 27th March, Monday, 2006
Where: Grad.  Lounge, Research Lab

The abstract and bio follow.

Hope you can make it for this interesting talk,



It is interesting how sometimes a subject you think you know wel
reveals new insights.  Taking our example from Lakatos' Proofs and
Refutations, you are invited on a little exercise into a subject we all
know:  Interprocess Communication in a single Operating System.
Starting here, we will then consider what happens when with each step as
we add new requirements for IPC between two computers, two more than one
instance of IPC, to N computers and finally N computers on the cheap. We
will consider how each step invalidates some assumptions or requires
additional mechanisms.  It is interesting to note when certain things
appear. But what is really remarkable are the insights it brings to our
concepts of network architecture. Insights that affect our concept of
layers and what goes in them with implications for all aspects of
networking including security, mobility, routing, etc.
