DECnet was designed by Digital as a way to interconnect their range of products. In its Phase IV implementation, released in 1983, it can support 63 areas of 1023 nodes each. The specifications for DECnet Phase IV are freely available. This has allowed others to provide DECnet connectivity in their products such as Sun’s Sunlink DNI, and now of course Linux. As with TCP/IP there are a number of higher-level protocols layered on top the basic DECnet protocol to provide services to applications. The ones currently available for Linux are DAP (Data Access Protocol, a File transfer protocol analogous to FTP in the TCP/IP world) and CTERM for remote terminal access (analogous to telnet).
