Description
To satisfy the requirements of US-CMS, D0, CDF, SDSS and other experiments, Fermilab
has established an optical path to the StarLight exchange point in Chicago. It gives
access to multiple experimental networks, such as UltraScience Net, UltraLight,
UKLight, and others, with very high bandwidth capacity but generally sub- production
level service. The ongoing LambdaStation project is developing an admission control
system for interfacing production mass storage clusters with these experimental
networks to enable bulk data movement. The goal is to design a system capable of
doing per flow based forwarding. One of the important sidelights of this project is
investigation of the behavior of end-node operating systems and applications in
the presence of per-flow rerouting. This article will introduce our findings and
current status of the research in this area. Our focus is on Linux as operating
system, and SRM (Storage Resource Manager), GridFTP, and dCache as network aware
applications.
