ISO Transport Class 2 Non-use of Explicit Flow Control over TCP RFC1006 extension

RFC 1859            ISO Transport and Flow Control          October 1995


   Note: The following description of the mapping is a repeat from the
   RFC 1006 standard.

   network service                 TCP
   ---------------                 ---
   CONNECTION ESTABLISHMENT

           N-CONNECT.REQUEST       open completes

           N-CONNECT.INDICATION    listen (PASSIVE open) finishes

           N-CONNECT.RESPONSE      listen completes

           N-CONNECT.CONFIRMATION  open (ACTIVE open) finishes

   DATA TRANSFER

           N-DATA.REQUEST          send data

           N-DATA.INDICATION       data ready followed by read data

   CONNECTION RELEASE

           N-DISCONNECT.REQUEST    close

           N-DISCONNECT.INDICATION connection closes or errors

   Mapping parameters between the TCP service and the network service is
   also straightforward:

   network service                 TCP
   ---------------                 ---
   CONNECTION ESTABLISHMENT

           Called address          server's IP address (4 octets)

           Calling address         client's IP address (4 octets)

           all others              ignored

   DATA TRANSFER

           NS-user data (NSDU)     data

   CONNECTION RELEASE

           all parameters          ignored
