INTEL RESEARCH TALK
NAME Luigi Rizzo University of Pisa
DATE Thursday 2nd October at 10am
PLACE Intel Research Cambridge, 15 JJ Thomson Avenue, Cambridge CB3 0FD
TITLE Robust processing of traffic in network nodes
In today's fast networks, nodes and routers can be subject to huge
amounts of incoming traffic, which can easily result in livelock and/or
denial of service. This affects especially the boxes that you put in to
protect or monitor your network.
In this talk we show how the problem originates from 'giving priority to
the wrong things', something that the conventional, interrupt-based
device driver model is particularly good at. We will then discuss how to
make a system robust in the face of input overloads, using a different
device model based on polling coupled with a simple but essential
scheduling scheme to guarantee resources to important userland tasks.
The techniques shown here have been integrated in the FreeBSD operating
(Work done while at ICSI, and supported by the XORP project,
