Please refer to fig. 3, which is a block diagram of a relay device according to the present invention, which mainly includes a USB interface module and an ethernet access module, wherein,
the USB interface module provides an access function for the data of the seamless network access equipment based on the Wi-Fi, and the transfer machine provides a data routing function to access the seamless network access equipment to a local network for surfing the Internet; the module consists of a USB bus driver and a corresponding function driver-network equipment interface driver, so that in an operating system at the side of the transfer machine, the USB interface module also represents a network card device and can configure an MAC address and an IP address for the network card; after proper route configuration, the data input by the USB interface can be forwarded to the Ethernet access module by a route to be accessed into a wired network.
The Ethernet access module provides an access function to a wired network, and accesses data accessed by the USB interface module to a local network through an RJ45 interface to surf the internet.
With the above modules, we preset two usage scenarios, which are explained as follows:
please refer to fig. 4, which is a diagram illustrating a scenario in which a wired portion accesses a wired network through a USB interface, where two network access manners exist, respectively:
a wired network: the device is forwarded to the wired network through the USB interface module of the device and the route of the transfer machine through the USB bus of the transfer machine, and meanwhile, the internet surfing function of the transfer machine is not influenced.
Wireless network: and accessing to a wireless network through a wireless network access module of the equipment.
Since there are two network access methods, network access management is important, in this scenario, a TCP/IP-based routing configuration tool is used to manage the connection to the device, and the user's connection can be configured to a wired network or a wireless network, depending on the specific implementation policy. We provide a traffic-based policy and a wireless signal strength-based policy for user selection.
Wireless signal strength based policy: if the wireless network signal is weak or the user sets through the interface, the data stream can be transmitted to the wired network to surf the internet, is connected to the transfer machine through the USB interface module via the internal gateway, is accessed to the 802.3 network via the transfer machine, and is then accessed to the fixed network of the operator.
Traffic-based policy: if the data volume of the Wi-Fi user accessed to the wireless network through the wireless network access module is larger than a set threshold value (can be modified), the data volume larger than the threshold value can be modified to be online through the wired network, connected to the transfer machine through the internal gateway and the USB interface, accessed to the 802.3 network through the transfer machine, and then accessed to the fixed network of the operator.
Please refer to fig. 5, which is a diagram illustrating a scenario in which a wired portion accesses a wired network through an RJ45 interface, and two network access methods exist in the scenario, which are respectively:
a wired network: access is made directly to the wired network through the RJ45 interface of the device.
Wireless network: and accessing to the 2G/3G wireless network through a wireless network access module of the equipment.
Similarly, since there are two network access methods, the network access management is important, and we use the TCP/IP-based routing configuration tool to manage the connection to the device, the user's connection can be configured to the wired network or the wireless network, depending on the specific implementation policy. We provide a traffic-based policy and a wireless signal strength-based policy for user selection.
Wireless signal strength based policy: if the wireless network signal is weak or the user sets up through the interface, can forward the data stream to the wired network and surf the net, access the fixed network of the operator through the RJ45 interface of the apparatus via the internal gateway.
Traffic-based policy: if the data volume of the Wi-Fi user accessing the wireless network through the wireless network access module is larger than a set threshold value (can be modified), the data volume larger than the threshold value can be modified to be accessed to the fixed network of an operator through the RJ45 interface of the equipment through the internal gateway.
