Each station in a TCP conversation will advertise a window which represents
the amount of buffer space that the station has available for this
conversation. The window size of a packet is the buffer available for the
station that is sending the packet, indicating to the recipient how much
data to send.
It is called a "sliding window" because it is variable and will change
throughout the course of the conversation.
For more detail on this, I would look at Douglas Comer's "Internetworking
with TCP/IP" volume I.
I have not seen a utility that will display the window size during the
transmission of the packet. A sniffer will display all of the packet fields,
but only after you have captured the transfer and opted to display it (but
of course you knew that already)...
