The aim of Purdue Infobahn is to benchmark the performance
of SBS at delivering user-specified QoS without resorting to
resource reservation and admission control, two central mechanisms
that impede scalability.
Guaranteed services are provided as part of the Purdue Infobahn
service suite for applications requiring strict per-flow QoS protection.
SBS will be compared with other IETF diff-serv
related architectures and benchmarked with multimedia applications
in the context of MSI.
SBS/Purdue Infobahn is supported by NSF grants ANI-9875789 [CAREER]
and EIA-9972883 with ANI-9714707, ESS-9806741 augmenting
end-to-end traffic/QoS control and
end system scheduling components of
the system.
Overview
The Network Systems Lab (NSL) houses people and research equipment
related to the study of networks and distributed systems.
Specific research areas include self-similar traffic control,
real-time/multimedia traffic control, Scalable Internet quality of
service provision architectures, distributed operating systems,
fault-tolerance in distributed systems, and ATM network security.
The research projects
are supported by
grants from NSF
(ANI-9714707, ANI-9875789 [CAREER], ESS-9806741, EIA-9972883),
PRF, and Sprint.
Additional equipment and software support is provided by
Cisco, FORE Systems, and Intel.

Purdue Infobahn QoS Testbed
Purdue Infobahn is a QoS testbed for implementing and
evaluating the SBS
wide area network QoS architecture developed at the Network Systems
Lab.
It is a private IP-over-SONET backbone network consisting of
a number of Cisco 7206VXR routers whose router software is being
customized to implement SBS' IP switching algorithm.
The phase I layout of the testbed is shown in the
Purdue Infobahn backbone diagram.
