APPARATUS FOR BEING SHARED IP ADDRESS BY PORT NUMBER

摘要

The present invention relates to an IP address sharing device using a port number in which a specific application hardware device shares an IP address with a PC using a port number for selecting an application protocol, and the device according to the present invention connects to the Internet. A first physical layer module for converting between a signal of a transmission medium and Ethernet data, a second physical layer module connected to a communication module of a PC and performing a conversion between a physical layer signal and Ethernet data, and for the specific application A third physical layer module connected to a hardware device (for example, an Internet telephone) and performing conversion between a physical layer signal and Ethernet data, and a port for transmission data input from the second physical layer and the third physical layer module Priority is given according to the number sent to the Internet through the first physical layer module to the transmission module and the third physical layer module A port number storage for storing a port number used in the connected specific application hardware device, and comparing a destination port number of the Internet data received through the first physical layer module with a port number stored in the port number storage device. It is composed of a receiving module for determining and sending to the second physical layer module or the third physical layer module.
