StkFw is a test support software solution that simulates environments in which multiple pieces of software and/or hardware work together on an IP network. In the development of software designed to work and cooperate with complex and valuable elements (software and/or hardware) on a network, the use of a testing program that simulates network element behavior is a well-known solution for reducing overall development costs. However, if the behavior (i.e., communication with other network elements) of the software being developed is complex, the initial costs of creating a test program may be high. StkFw can be used to facilitate the control of data communication on an IP network based on its superior user interface. It simulates behavior identical to that of testing programs and reduces the overall cost of testing during the target software's development by eliminating the need to create a dedicated testing program.

StkFw works on systems with the following specifications:

• CPU: 1 GHz or more
