Problems solved by technology

In each local area network, multiple network devices need multiple virtual network addresses to connect to the virtual private network server. In this way, because the fixed network address and multiple virtual network addresses are required at the same time, the network system 10 needs to be updated. Large construction cost, and it can only provide connection between one local area network and another local area network through point-to-point mode

Abstract

A network system and a connecting method thereof. The network system includes a first network device having a first MAC address, a second network device having a second MAC address, a first IP-based device having a first IP address for transmitting the data to the first network device through the first MAC address, a second IP-based device having a second IP address for receiving the data outputted from the second network device through the second MAC address, and a host having a predetermined IP address and being connected to the first IP-based device and the second IP-based device through the predetermined IP address, the first IP address, and the second IP address. The host has a look-up table for recording the first MAC address mapping to the first IP address, wherein the second IP-based device checks the look-up table for directing the data to the first IP-based device.

Description

technical field [0001] The present invention relates to a network system and its connection method, in particular to a network system with a network device capable of exchanging data (data transaction) with the Internet through a media access control address (media access control address, MAC address) and the Internet. its online method. Background technique [0002] With the growth and popularization of the Internet, various Internet-related application devices have emerged. For example, data can be uploaded from a client to a remote host in the same Internet system. ) or other clients, or download (download) data from a remote host or other clients in the same Internet system, wherein the Internet system uses network addresses (IP addresses) to establish network protocols (network protocols) to transmit packets. In addition, the same building uses a local area network (LAN) to transmit packets. Therefore, when a terminal in one local area network wants to transmit data to...
