Tracerouting a list of internet hosts

摘要

A method and system for monitoring the internet is defined. An embodiment of the invention invovles the following steps: providing a traceroute specification and a set of global defaults; parsing the specification into its constituent parts; setting up a transaction request message; creating a TCP/IP socket and setting up input/output access to it; and for each potential "hop" up to the maximum allowed, sending a "ping" to the destination with the max allowed hops for that "ping" and setting the message to one more than the ping to the previous potential hop (where the numbering started at one); noting the timestamp for that ping transmission; waiting for a reply from the ping; noting the timestamp for that reply when it arrives and then calculate the time taken from transmit to reply; and closing the socket and server connection.
