???: HOW TO CONNECT TP4 AND TCP/IP NETS :??? ---------------------------------- I need make our Unix-V.2-like 680x0-system network using OSI/TP4 (but not TCP/IP) to support such nice things as: NFS, RFS, TELNET, Rlogin, Remote Proc Call so they can cooperate with another 680x0-systems run under V.3(V.4) supporting TCP/IP (but not TP4). There is another system-family (a 386-based) that fortunately supports both TP4 and TCP. An idea I have, is to add a gateway system converting TP4 <-> TCP, and then write a "black box" leyer between NFS, Telnet, ..., and TP4: +-----+ +--------+ +--------------+ ! NFS !...! Rlogin ! ! NFS...Rlogin ! +-----+---+--------+ +-------------------+ ! ! ! black box appl ! ! Gateway + ! ! ! ! conv TP4/TCP ! ! conv TCP/TP4 ! ! ! +------------------+ +----------+--------+ +--------------+ ! ISO 8073 Cl4 ! ! 8073 Cl4 ! TCP ! ! TCP ! +------------------+ +----------+--------+ +--------------+ ! 'Ethernet' !-------! Eth. ! Eth. !-------! Eth. ! +------------------+ +----------+--------+ +--------------+ system in system in OSI-network Gateway (386) TCP/IP-network Questions: 1. Is it possible to translate TCP/IP <--> ISO8073 Cl4? 2. Is it easy to write a "black-box" and Gateway session layer programs? Or maybe it exists somewhere???? 3. Will NFS, Rlogin,... be satisfied by such an arrangement?
