hello every body

i m working on a project that's need to calculate the shortest i e . i need to check which machine is near to my system . so foe this i m using sockets. I m having a array list in which all the system ip address are listed . so i need to check which ip is near to my system. For that i m sending a test packet to each ip sequently n get the reply from that ip system . until i get reply i will not send another test packet to other system i.e i m taking synchronous reply.

So my problem is how can i calculate the time span in sending a packet n receiving a packet . this transmitting n receiving gets with in milliseconds . so how can i calculate the shortest path .

If u r having any other option so please share with me

From,
Arun

Solution 1

use Ping and PingReply. The PingReply shows the RoundTripTime.

in that case you have to Ping with a hard set TTL. This is the basic TraceRoute command in effect. Start with 1 and stop till ipaddress matches the other computer. But even than you can find 100 computers on step 2 as first pc results
