Abstract
A local area network compliant with universal serial bus (USB) standard includes a USB switching hub and a plurality of hosts. The USB switching hub is used for packet transmission and receiving, wherein the USB switching hub is compliant with USB standard. Each of the hosts is coupled to the USB switching hub. Each of the hosts includes a network control unit and a USB host unit. By the USB switching hub for packet transmission, USB can be used as a way of communicating among the hosts. Thus, networking can be achieved without network cards, resulting in convenience in use and reduced costs.
Claims8
A local area network compliant with universal serial bus (USB) standard, comprising:
- a USB switching hub for transmitting a first packet and for receiving a second packet, wherein the USB switching hub is compliant with USB standard;
- and
- a plurality of hosts, coupled to the USB switching hub, for receiving the first packet from the USB switching hub, and for transmitting the second packet to the USB switching hub, each of the hosts comprising:
- a network control unit for outputting the second packet according to a request from a program executed in the host, and for outputting data to the program according to the received first packet;
- and
- a USB host unit, coupled to the USB switching hub and the network control unit, for transmitting the second packet outputted from the network control unit to the USB switching hub, receiving the first packet from the USB switching hub, and outputting the received first packet to the network control unit.
A switching hub compliant with universal serial bus (USB) standard, for use in a local area network, the local area network having a plurality of hosts, the switching hub comprising:
- a peripheral bus;
- a plurality of USB peripheral units, coupled to the peripheral bus and capable of being coupled to the respective host units, for transmitting and receiving a packet among the peripheral bus and the hosts;
- and
- a central processing logic unit, coupled to the peripheral bus, for receiving the packet, and outputting the packet according to the packet's destination after conversion.
