Hi,

The next nets seminar takes place today at 4pm and will be given by Lucian 
Popa, from UC Berkeley. Lucian will present his work on Internet 
Architecture entitled Rule Based Forwarding, which was recently published in 
HotNets 2009.

Where: 6.12 MPEB
When: 4pm, monday December 7th

Title: Rule-based Forwarding (RBF): improving the Internet’s flexibility and 
security

Abstract: From active networks to the more recent efforts on GENI, a 
long-held goal of Internet research has been to arrive at a network 
architecture that is flexible. An unfortunate stumbling block in these 
efforts has been that flexibility is fundamentally at odds with another 
long-held goal: that of devising a secure network architecture.
In this paper, we propose a new architectural concept – that of packet 
rules – and develop a rule-based forwarding architecture (RBF) that we argue 
is both flexible and secure. A rule is a simple if-then-else construct that 
describes the manner in which the network should – or should not – forward 
packets. In RBF, instead of sending packets to a destination (IP) address, 
end-hosts send packets using the destination's rule. At a high-level, the 
reason RBF achieves both security and flexibility is that, with rules, a 
user can specify both what packets it is willing to receive as well as how 
it wants these packets forwarded and processed by the network.

Short bio: Lucian Popa is a PhD student at the EECS department of the 
University of California Berkeley, advised by Ion Stoica. His research 
interests span the area of networking, including network architecture, 
network monitoring, energy efficient networks and wireless networks. Lucian 
Popa has a BS and an MS in computer science from the Politehnica University 
of Bucharest in 2003 and respectively in 2004.

This is exciting work. All welcome!

Cheers,
Costin
