31 results about "Network Driver Interface Specification" patented technology

The Network Driver Interface Specification (NDIS) is an application programming interface (API) for network interface cards (NICs).

Control method, device and system

The invention discloses a control method, a control device and a control system. In the embodiment of the invention, remote network driver interface specification (RNDIS) equipment is controlled by encapsulating a control command in a network data packet transmitted to RNDIS equipment and transmitting the encapsulated network data packet to the RNDIS equipment. Because customer premise equipment can directly transmit the network data packet to the RNDIS equipment in the conventional network architecture, the scheme can be adopted to transmit the control command to the RNDIS equipment without an additional new control interface; compared with the scheme that the additional new control interface and a driving program need to be installed in the prior art, the scheme of the invention has the advantage that the complexity of the use is reduced; and the method, the device and the system do not have special requirements on the RNDIS equipment and have general applicability and are easy to implement.

Method for judging process of TCP/IP packet in driver layer

The invention discloses a method for judging a process of a TCP / IP packet in a driver layer, which can accurately distinguish the process of a packet in a network driver interface specification (NDIS) filter driver. The technical scheme comprises that the method comprises the following steps of: when a certain program uses a Windows socket interface, loading a layered service provider through a certain process; acquiring an identification number of the process and a source port opened by the process by the layered service provider; judging whether the process is an interested process according to the identification number of the layered service provider; if the process is the interested process, transmitting a user datagram protocol (UDP) notification packet to a specific address and a port; receiving the UDP notification packet, extracting the identification number of the process, a protocol used by the process and the source port opened by the process from the UDP notification packet, saving the identification number of the process, the protocol used by the process and the source port opened by the process as an association table, and discarding the UDP notification packet by using an intermediate layer driver / filter driver normalized by a network driver interface; and when the intermediate layer driver / the filter driver receives another TCP / IP packet transmitted by a local host, judging whether the TCP / IP packet comprises the information consistent with the contents in the association table, and determining the identification number of the process to which the TCP / IP packet belongs according to the judgment.

Wireless network card and method for operating same

The invention provides a wireless network card and a method for operating the same, and relates to the field of wireless communication. The wireless network card comprises a self-installation program module, a self-starting module and a main program module. The self-installation program module is used for storing an execution program which can be applied to a terminal and corresponds to the wireless network card, whether the execution program is installed in the terminal or not is detected after the network card is inserted into the terminal, and the execution program is installed in the terminal if the execution program is not installed in the terminal; the self-starting module is used for detecting whether remote network driver interface specification (RNDIS) ports are available on the terminal or not, and the execution program in the terminal is started if the remote network driver interface specification ports are available on the terminal; the main program module is used for matching an APN (access point name) for the terminal, and the terminal can be automatically connected with a network via the execution program under the effect of the main program module. The wireless network card and the method have the advantages that the terminal can be automatically networked in a simple and speedy mode after the wireless network card is inserted into the terminal, and accordingly user operation can be reduced.

A network access system and method based on ndis filter driver

The invention relates to a network admission system based on an NDIS (Network Driver Interface Specification) filter driver. The network admission system comprises an enterprise internal system, a client, NDIS admission equipment and an authentication server, wherein the NDIS admission equipment comprises an application layer program module and an NDIS filter driver module; and the authentication server is used for providing a Web authentication page. The method comprises the following steps: connecting a computer to the NDIS admission equipment through switch equipment, and connecting the NDIS admission equipment, the authentication server and the enterprise internal system to the Ethernet through a three-layer switch respectively; and releasing, discarding or redirecting past data packets by the NDIS admission equipment according to a computer not passing identity authentication and a computer passing the identity authentication. Through adoption of the network admission system, a network admission function is realized through the NDIS filter drive module based on the NDIS admission equipment. The network admission system is high in universality, low in cost, and convenient for installation and maintenance. Moreover, a redirected data packet is directly constructed on a driving layer, so that the working efficiency is increased effectively.
