Neer) Newsgroups: comp.protocols.tcp-ip.ibmpc Subject: questions on TCP spec. Message-ID: <1719@cod.NOSC.MIL> Date: 6 Dec 89 22:23:14 GMT Reply-To: neerma@cod.nosc.mil.UUCP (Merle A. Neer) Organization: Naval Ocean Systems Center, San Diego Lines: 19 I need some clarification on the TCP spec in a couple of areas. 1. Is 'keepalive' a TCP option or merely a implementation feature? Where is it documented. 2. What should the behavior of a sending TCP be once it has retransmitted a segment a maximum number of times? What is the maximum number of times? Assuming it should close the connection, should it inform the user? Thanks, Merle neerma at nosc.mil 619-553-3974
