Message transmission processing method and device

Abstract

The embodiment of the invention provides a message transmission processing method and device, is applied to relay network equipment, and belongs to the technical field of local area networks. The method comprises the following steps that: in response to an association request of terminal equipment, association connection with the terminal equipment is established, the terminal equipment and main network equipment corresponding to the relay network equipment being in a disassociated state; a first communication message sent by the terminal equipment is received; an address resolution protocol message is created according to the MAC address information of the relay network equipment and the source IP address information of the terminal equipment; and the address resolution protocol message is sent to the main network equipment, wherein the address resolution protocol message is used for updating an address resolution protocol table entry in the main network equipment, so as to make a second communication message sent by the main network equipment based on the updated address resolution protocol table entry pass through the relay network equipment and then transmitted to the terminal equipment. According to the method and device of the invention, normal communication between the main network equipment and the relay network equipment in the roaming process of the terminal equipment is realized, and the roaming experience of the terminal equipment of a user is improved.

Description

technical field [0001] The present application relates to the field of local area network technology, and in particular to a message transmission processing method and device. Background technique [0002] In a relay network, there are generally the following roles: main network device, relay network device, and terminal device. In practical applications, the user can connect to the main network device through a wireless relay network device, thereby expanding the coverage of the wireless signal, and the terminal device can roam within the signal range of the main network device and the relay network device. However, during the roaming process from the main network device to the terminal device through the relay network device, there are often communication terminal problems. The following examples illustrate: [0003] Suppose the Media Access Control Address (MAC) address of the primary network device is 00aa.bbcc.dd01, the IP address is 192.168.1.1, the MAC address of the...

[0008] During the application process, the terminal device moves within the coverage of the main network device and the relay network device. Suppose it moves from a position close to the main network device to a position close to the relay network device. At this time, the terminal device and the main network device are disconnected. Association, and associated with the relay network device, according to the roaming algorithm preset by the terminal device, the terminal device will roam, and the message sent by the terminal device will pass through the relay network device and be transmitted to the main network device. During the process from the device to the relay network device, the MAC address will change. However, the ARP table of the main network device will not actively change at this time. When the main network device sends a message to the terminal device, it will still follow the previous (that is, the ARP table of the main network device is still as shown in the above table, and the correct ARP table of the main network device is shown in the table below), which will cause the main network device to fail to complete the process through the relay network device and the terminal device. Normal communication, poor user experience
