There are a lot of applications imaginable for using an IP-Proxy. In following 3 possibly applications are described.
GPS Data Evaluation
[1] IP-Proxy receives GPS data from a
serial interface (e.g. GPS mouse) and redirects
these data via IP/UDP to a remote location
[2] on remote side an IP-Server application receives the GPS data and forwards these data via Inter-Process Communication (IPC) to a Geo-Tracer application
[3] the Geo-Tracer application
visualize the GPS data on a map
Protocol Conversion
[1] an UDP-Client application, running on a Windows system, sends out data via IP/UDP thereby these data shall be processed by a TCP-Client application on a Linux system
[2] on the Linux system an IP-Proxy receives the data from the UDP-Client and redirects these via IP to a TCP-Client application on the same system
[3] the TCP-Client application on Linux system processes the data
Data for a Multicast-Group on Linux Server
[1] a TCP-Client application, running on a Windows system, sends out data via IP/TCP thereby these data shall be provided to a multicast-group on a Linux-Server system without graphical user interface (GUI)
[2] on the Linux-Server system, an IP-Proxy receives the data from the TCP-Client and forwards this data via IP/UDP to the multicast-group defined on this system
