Problems solved by technology

[0003] Therefore, the AP needs to maintain a table that records the MAC address and the corresponding interface, so as to find the interface to be forwarded according to the MAC address. Since the two interfaces are associated with the wired interface and the wireless interface at the same time, the hardware chips of the two interfaces are different, so software maintenance must be used, which is wasteful. resources, and addressing is required even for wireless APs with only two interfaces. The addressing process will consume CPU resources and affect the packet forwarding speed. Similarly, for other bridges with only two interfaces, there these deficiencies

Embodiment Construction

[0031] In the same conflict domain, the message is sent by the whole network, and the bridge connects several conflict domains. After receiving the message, it determines the conflict domain to which the message belongs according to the destination address of the message and the CAM table, and then For the case of forwarding packets between two interfaces, if you still need to search the CAM table to find the outgoing interface, a lot of resources will be wasted and the speed of packet forwarding will be affected. The embodiment of the present invention provides a method and device for forwarding a dual-interface message, which handles the case of forwarding a message by a dual-interface bridge, so as to save resources and increase the speed of message forwarding.

[0032] Such as figure 1 As shown, the message forwarding method provided by the embodiment of the present invention includes:

[0033] Step S101, obtaining the destination address of the message received by the fi...

Abstract

The invention discloses a method for transmitting messages by a network bridge and a network bridge, which relate to the technical field of communication. The method for transmitting messages by a network bridge with double interfaces comprises obtaining destination address of messages from the message received by a first interface in the network bridge with double interfaces, searching the destination address in the a first address table of a collision domain connected with the first interface, and transmitting the messages to the collision domain connected with the second interface through the second interface in the double interfaces when the first address table can not find the destination address. The method and the network bridge simplify the searching process, reduce resource consumption, and improve the transmitting speed of the messages.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message forwarding technology. Background technique [0002] The current wireless AP (Access Point, Access Point) uses bridging to forward packets between the wired LAN and the wireless LAN. Many MAC (Media Access Control, Media Access Control) addresses are stored in the AP. These MAC The address is stored in the CAM (Content-Addressable Memory, content-addressable memory table). After the AP ingress interface receives the packet, it needs to search the CAM table to find the egress interface, and then the corresponding egress interface sends the packet. [0003] Therefore, the AP needs to maintain a table that records the MAC address and the corresponding interface, so as to find the interface to be forwarded according to the MAC address. Since the two interfaces are associated with the wired interface and the wireless interface at the same time, the hardware chips of th...
