        Does anybody know how TCP differentiate node/process crash with
network partition problem? In particular, when socket return these 3 errors:
ENETDOWN (network is down), ENETUNREACH (network is unreachable) and
ENETRESET (network dropped connection on reset)? I also would like to know
how TCP detect and handle all these problems?
        I can't find any details about exception detection and handling from
most of the materials. Please helps!!
        Any repsonse please direct to me. I will summarize to the net if
enough interest. Thanks.

        Regards.
