Hi, I have a trace saying
"Data provided by WAND Research Group using the dag interface card OC48 data analysis required CAIDA's CoralReef software suite."
I am confused by the statement of "OC48 data analysis required CAIDA's CoralReef software suite".
It seems to me that traces captured by dag card are collections of packet headers. And I can use Tcpdump or CoralReef libary in reading the packet information from the trace. And I even can directly read header by header (IP+TCP/UDP/or other+..) from the trace by my own program, and interpret the information in packet by matching the structure specified in RFC.
Then why "OC48 data analysis required CAIDA's CoralReef software suite"?
I apply the tcpdump on the trace, it also can print out the packet information. But when I write my own program to parse through the trace, I can not get right information. Why is that?
Thanks, zs
