Basic bridging questions pls answer

[Anand S. Katti]

Hello All,

It may be simple, but still im getting confused please do answer these.

	FTP SERVER
LAN		|
--------------------------------
	|
-------HUB1--------------------HUB2-----
	|			|
	AP1			AP2
	|			|
	Client1.................Client1

In the above figure, a client moves from AP1 to AP2 with a ftp session ON.
1. How the FTPSERVER will know that Client1 has now moved to HUB2?

2. Will AP2 inform AP1 about client1's new position ?

3. how does the HUB1 know that client 1 is now in HUB2 path ?

4. If client with ftp session on moves fast from AP1 to AP2, and then
associates with AP2, then will the ftspsession continue ? with out
connection lost error ?

is this handoff ?

or it is because of the nature of TCP? since c1 moves to AP2 before the
keep alive timer expired ?

Thanks in advance,

Anand
