Probe will be used to perform early testing of ESnet III. Later this year Oak Ridge and NERSC nodes will be upgraded to OC12 (655 megabits/second). At that time the bandwidth testing will be repeated and lessons-learned implemented in production HPSS-HPSS transfers.

(July 2001). As mentioned above ("Improve ORNL-NERSC bandwidth"), ESnet III OC12 connectivity is now in place and high-bandwidth transfers are being tested. Changes to correct some observed difficulties have already taken place and are being evaluated.

(November 2001). Router hardware problems have been resolved. Relationships have been established which will make future debugging easier. Performance is now more symmetric, predictable and understandable. "Early testing" is complete.
