large web server -- rt: Hash functions derived from the routing code

This dataset is from a web server farm (a web portal), with the server farm running on a single virtual IP address [*]. I have accumulated the /proc/net/ip_conntracks from all servers in the farm. There are 37608 unique conntrack entries (75216 tuples to hash), and all but 2385 of them refer to the virtual service IP and port 80. This dataset is to show the extreme case of a single-address-and-port server.
