Transports are background programs that transfer messages between networks. Some channels have a client component that interfaces between the server and the local computing environment. Others, such as SMTP/MIME, act as full peer message transfer agents (MTAs). Each transport program supports multiple channels.
The NJE Transport provides a method of transferring messages between IMTA SMCS, and mail systems running the NJE networking protocols, such as PROFS/OfficeVision. The NJE Transport treats the host as a virtual NJE node, making the addressing nomenclature transparent. FIGURE 1-1 shows the paths of communication. Network paths are marked in black. Paths in grey represent components that communicate with each other via network paths.The OS/2-based PC acts as a TCP/IP-to-SNA gateway for transporting PROFS/OfficeVision messages. When this is complete, changes must be made to the appropriate configuration files located on the VM Host and the OS/2-based PC.
The files affected during NJE/PROFS installation are shown in Figure 1-1.
