sir,
I am having a basic question in networking?

I read that TCP connection will have a virtual cicuit
(ie)only the first packet will contain destination ip and the
remaining packets will follow the path(pushing of packets)
My question is how the second & the other packets will follow the
path??
(My guess is FCS(frame check sequence) and how the second packet will
follow the path and asking the follow up of first & other packets???)
Help me
Thks in adv

You read wrong! All packets have both the source and destination
addresses. The circuit is virtual in more than one sense, ie., two
packets headed for same destination may take _different_ physical
paths to get there -- part of the reason TCP/IP is so robust.

Perhaps you were reading something that was referring to packet
fragmentation -- but that's just a guess.

BTW if you're wanting to "see" how network protocols work, I highly
recommend Ethereal as a free/OSS package that will help _very_ much.
