Meeting started at 12:45 p.m. CDT. 

Steven reported on the status of tests with VFER. In the real app, server is able to create 
300 triangles in 10 seconds; has not actually measured the data rate. The test runs from 
small to intense rates (real app is around 60 Mbps). Not sure if they’re misinterpreting the 
output from VFER; in some cases, it appears that VFER is retransmitting in excess of 
required/expected amount.

Stanislav asked Steven to ensure that this problem was reported to the list. Ivan reported 
that, to date, he didn’t recall seeing this problem. Ivan reported no known problem with 
stats collection. 

Previously, Steven’s group was not using UDP but, instead, a protocol they’d created 
themselves; this means that the new protocol was entangled with the application, from 
their POV.

Yee-Ting asked if VFER would be developed to production level (as with Grid FTP). 
Ivan pointed out that the code base is not yet stable; he’d like to develop a list of 
specifications to which he can build VFER. Yee-Ting asked about ephemeral port 
numbers/fire walls; he noted that a lot of stuff is filtered and asked if there was a 
specified port number range. Stanislav noted that, after integration, there will be one (or a 
small few) port numbers that could be opened in the firewall. 

Meeting was adjourned for lack of quorum. Call ended at 1:00 p.m.
