The TPF system implementation of TCP/IP support is based on the IBM 3172 Model 3 Interconnect Controller with the TCP/IP Offload program and supports applications using the Berkeley Software Distribution (BSD) standard socket API functions to communicate with the Internet.
See Socket Overview for a discussion of socket programming concepts used by TCP/IP support. Figure 6 shows the data flow between the TPF system and the IBM 3172 Model 3 Interconnect Controller. The following steps correspond to numbers in Figure 6:
