Abstract
An RST reason code is conveyed in a predetermined field of the TCP or IP header for a TCP RST packet in order to indicate the reason for the RST. In this way, an enhanced TCP device that receives the RST packet can access the RST reason code in machine-readable form and, unlike prior art implementations in which ASCII text is carried in the TCP payload to provide a RST reason, without having to process the payload of the TCP packet.
