Success Case

Problem

Shanghai Ruiyao Network Technology Co., Ltdreceived email with from Randy Sobie expressing concerns over the data transfer rates from U Victoria in British Columbia, Canada to SLAC

Hi Les
We spoke a while ago about connectivity between SLAC and Victoria.
In the new year UVictoria will be hosting one of the babar working data sets (tau working group).
This will likely require the transfer of ~10 TB of data in Feb-Mar.Currently we can transfer data to SLAC (we produce babar MC samples) and we copy analysis data
to UVic at rates around 30 mbits/s using a BbkImport command of babar.
This command uses
bbftp and 10 streams.
We are wondering how we can improve the transfer rate. Our routing to SLAC from
Victoria (mercury.uvic.ca) is unfortunately not direct and we go to Calgary before entering the US.I have cc'ed this email to Ian Gable who is the HEPNET/Canada technical manager,
Thomas Tam of CANARE and Ashok Agarwal of UVic (Ashok does most of the data transfer).
We recently set up a lightpath between UVic and TRIUMF. Some of our colleagues in
Vancouver have a lightpath to Fermilab. I am told that a lightpath solution may not
be possible in the short-term.
