How to check the path between switchers?

[Eric]

Does anyone have any suggestions on detecting IP between switchers?
My server sends packet to specific IP address based on internal logic, then
the packet will transfer between many switchers. Recently, some packets are
missing with unknown cause, and I would like to find it out what cause the
problem. Does anyone have any suggestions on what kind of tools I should use
to detect the problem?
Thanks in advance for any suggestions

I think you mean routers?

Try traceroute and pathping
