Abstract

The present invention relates to a gateway device based on the Linux kernel, comprising: a first device port connected to at least one LAN port, used to virtualize at least one virtual LAN port, and also used to receive data packets sent by at least one LAN port, and Send the processed data packet to the corresponding virtual local area network port, and also be used to receive the data packet sent by at least one virtual local area network port, and send the processed data packet to the corresponding local area network port; the second device port, and the wide area network port The connection is used to virtualize at least one virtual wide area network port, and is also used to receive the data packet sent by the wide area network port, and send the processed data packet to the corresponding virtual wide area network port, and is also used to receive the data packet sent by the virtual wide area network port, and sending the processed data packet to the wide area network port; each of at least one virtual local area network port is correspondingly bound to and only one virtual wide area network port.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a Linux kernel-based gateway device and a communication method. Background technique [0002] Multicast technology is a point-to-multipoint network technology, and its purpose is to reduce the load of the network and the burden of the media server. From a protocol point of view, the protocol used in IP multicast consists of two parts: the multicast management protocol IGMP (Internet Group Management Protocol, multicast membership protocol) running between the host and the multicast router and the multicast membership protocol running in each A multicast routing protocol between multicast routers. At the same time, in order to suppress the spread of multicast data in the layer 2 network, the IGMP snoop function is introduced, and in order to allow the IGMP protocol to penetrate the layer 3 network, the IGMP proxy function is introduced. However, current home gatewa...
