i was reading about "MOBILE IP"..
they said that :
assume initially we were connected to your home network and then you moved to another network...there is a problem that the person who was communicating with you will be using your old ip address ( that of you home network)...however you are no longer in your home network...
my question is :
where is the problem !?!! lets say im talkin to my friend on msn..and she changed her network..i still can talk to her because when the transport layer establishes a connection with her again,,it will be using her new ip address !
why would we need to keep the old ip address :S i dont get it..could anybody please help me out here. thx
