There was some trouble in collecting this trace which may reflect the elevated values for fragmentation in direction = 1
This data was collected using the OC48MON2 located at Metromedia Fiber Network (MFN) in San Jose, CA
Data collection : 10/29/2001 14:00
oc48 data analysis required CAIDA's CoralReef software suite.
