NI Network Interface

The NI protocol ( Network Interface) is used by SAProuter, all SAP programs, and development kits for CPI-C and remote function call (RFC).

In the OSI 7 layer model, the NI layer forms the upper part of the transport layer. The NI protocol uses TCP or UDP. The protocol is also known as the SAP protocol.

The NI layer uses the transport layer in OSI-7 layer model and forms the SAP interface to the application-oriented layers .

The test program niping, which tests the NI functions, belongs to the NI layer. A predefined number of data packages is sent from the client to the server, is returned by the server, and read again by the client. In addition, average transfer times and detailed information (depending on the trace level) about the data transfer are displayed. The test program niping can be used to test network connections with or without SAProuter.
