Appendix 6. Fermilab Status Update

As the startup of LHC approaches, Fermilab has continued to enhance and upgrade its wide area
network facilities and services. At the network infrastructure level, the deployment of the
Chicago Area MAN has positioned the Laboratory to meet the immediate needs of the US-CMS
Tier-1 facility, as well as satisfy any longer term requirements that might emerge from the LHC
or other collaborative project. In the area of wide area data movement, the Laboratory continues
to advance the deployment of end-to-end data circuit technologies, in direct support of its
collaborations. Finally, at the user level, Fermilab has implemented a wide area network
performance analysis methodology to troubleshoot and debug network performance problems of
its collaborators. Successes in all three areas have significantly improved the Laboratory's
overall wide area network capabilities in 2007, and are expected to provide continued
improvements in 2008.
Chicago Area MAN:
In 2007, Fermilab completed the upgrade of its wide area network facilities to be based entirely
on a metropolitan area network (MAN) architecture. The Chicago area MAN, a collaborative
effort among Fermilab, Argonne National Laboratory, and ESnet, was completed in November,
2007, and is now fully operational. The MAN is based on an optical fiber ring connecting the
two Laboratories and two international network exchange points in downtown Chicago, StarLight
and the Level-3 point-of-presence (PoP). The MAN's ring architecture (Figure 16) provides the
Laboratory with fiber path redundancy for its wide area network connections.

Dense wave-division multiplexing (DWDM) equipment located at the four MAN hubs provides
10Gb/s point-to-point data channels for the Laboratory to connect to ESnet and other research &
education networks available at the network exchange points.
