Network Working Group Marshall T. Rose, Dwight E. Cass Request for Comments: RFC 1006 Northrop Research and Technology Center Obsoletes: RFC 983 May 1987 ISO Transport Service on top of the TCP Version: 3 Status of this Memo This memo specifies a standard for the Internet community. Hosts on the Internet that choose to implement ISO transport services on top of the TCP are expected to adopt and implement this standard. TCP port 102 is reserved for hosts which implement this standard. Distribution of this memo is unlimited. This memo specifies version 3 of the protocol and supersedes [RFC 983]. Changes between the protocol as described in Request for Comments 983 and this memo are minor, but are unfortunately incompatible. M. Rose & D. Cass
