Network device and its data transmission method
First Claim
1. A network device for transmitting data of a host system to a network, comprising:
- a buffer for data storage;
a first transmission interface for providing a control signal to the host system, when the host system receives the control signal, the host system starting to transmit the data and the first transmission interface storing the data in the buffer; and
a second transmission interface coupled to the buffer for transmitting the data from the buffer to the network;
wherein when the first transmission interface provides the control signal, the second transmission interface activates a frame transmission procedure; and
when the data are completely transmitted to the buffer after a frame transmission pre-procedure is finished, the data are read from the buffer and transmitted to the network,wherein the frame transmission procedure comprises a carrier-sense, a network channel contention, and steps of transmitting a preamble, a header and a frame body.

Abstract
A network device for transmitting data of a host system to a network including a buffer for storing the data, a first transmission interface providing a control signal to the host system, and a second transmission interface coupled to the buffer for transmitting the data from the buffer to the network. A data transmission method of the network device includes the following steps: providing a network device and a host system, wherein the network device is providing a control signal to the host system, and the network device immediately activates a frame transmission procedure after providing the control signal; the host system starting to transmit data to the network device after the host system receives the control signal; and the network device transmitting the data to the network after a frame transmission pre-procedure is finished and when the data of the host system are completely transmitted to the network device.

5. A data transmission method of a network device comprising the following steps:
-
a. providing a network device and a host system, wherein the network device is provideable a control signal to the host system, and the network device immediately activates a frame transmission procedure after providing the control signal; b. the host system starting to transmit data to the network device after the host system receives the control signal; and c. the network device transmitting the data to the network after a frame transmission pre-procedure is finished and when the data of the host system are completely transmitted to the network devices, wherein the frame transmission procedure comprises a carrier-sense, a network channel contention, and steps of transmitting a preamble, a header and a frame body. - View Dependent Claims (6, 7, 8, 9)

10. A data transmission method of a network device comprising the following steps:
-
a. providing a network device having a first transmission interface and a second transmission interface, the first transmission interface being for receiving data of a host system, the second transmission interface being for transmitting the data to the network; b. the network device providing a control signal, wherein after the host system receives the control signal, the host system starts to transmit the data to the first transmission interface, and the second transmission interface activates a frame transmission procedure; c. checking whether the data of the host system are completely transmitted to the network device after a frame transmission pre-procedure is finished; and d. transmitting the data to the network when the data of the host system are completely transmitted to the network device;
or the network device abandoning a network channel authority when the data of the host system are not completely transmitted to the network device,wherein the frame transmission procedure comprises a carrier-sense, a network channel contention, and steps of transmitting a preamble, a header and a frame body. - View Dependent Claims (11, 12, 13)
