Looking for a TCP/IP networking library/module/whatever ...

[Storm]

... that I would like to use in a client/server application that would
:

1) detect reliably when connection is lost and try automatically to
reconnect to the server and the link is declared dead (i.e. the
client/server is notified) if only a reconnect was not possible for
3-4 minutes

2) perhaps have the whole link encrypter, but I see this most as a
bonus

Anyone knows if something like this exists ?
