Problems solved by technology

[0006] In the prior art, when the upper-level device communicates with the lower-level device, ARP Proxy needs to send an ARP Request broadcast message for each VLAN of each lower-level device , and ARP Proxy needs to send different ARP Request messages for different VLANs, the efficiency of ARP Proxy sending packets is low, and the implementation is more complicated

Embodiment Construction

[0023] like Figure 6 As shown, it is a flowchart of a method for improving the efficiency of address resolution protocol proxy contract sending in an embodiment of the present invention, which specifically includes the following steps:

[0024] Step S601, receiving an ARP Request message. ARP Proxy receives the ARP Request message sent by a user (host) of a certain SubVLAN, and requests the MAC (Media Access Control, Media Access Control) address of a certain user of a certain SubVLAN under the SuperVLAN to which the ARP Request message includes the sender MAC address and IP address of the device.

[0025] Step S602, replacing the MAC address of the sending end device and the SubVLAN to which the sending end device belongs in the ARP Request message, and sending an ARP Request message with the replaced MAC address and SubVLAN to each device under the SuperVLAN.

[0026]Specifically: after receiving the ARP Request message sent by the sender device, the ARP Proxy records the...

Abstract

The embodiment of the invention discloses a method for improving address resolution protocol (ARP) acting package transmitting efficiency, including the following steps: an ARP request message is received; the media access control (MAC) address of the transmitting end equipment of the ARP request message and the sub virtual local area network (SubVLAN) to which the transmitting end equipment belongs are replaced; moreover, an ARP request message of the replaced MAC address and SubVLAN is transmitted to each equipment of a super virtual local area network (SuperVLAN). With the embodiment of the invention, ARP Proxy only transmits one ARP Proxy request message to each equipment of the SuperVLAN, thereby improving the package transmitting efficiency of ARP Proxy under cascade connection and lowering the implementation complexity of ARP Proxy under cascade connection.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, and in particular to a method, device and system for improving the efficiency of sending out packets by an address resolution protocol proxy. Background technique [0002] With the rapid development of network communication, in some access network structures and other network structures, network devices (especially access devices) are required to adopt a mixed layer-2 and layer-3 network. viewed as a system such as figure 1 As shown in the figure, the system can be regarded as a large three-layer device externally. Generally, the side connecting the system to the core network or a higher-level network is called the "network side", and the side connecting the system to the edge network or user network is called the "user side". For the network side and the user side, this cascaded system should be able to shield the difference between whether it is one dev...
