Problems solved by technology

[0007] If there is a lot of traffic in the network, the CPU will be greatly impacted instantly, the utilization rate is high or even overloaded and paralyzed, and if multiple SUPERVLANs need to learn ARP at the same time, since the packets sent by all SUPERVLANs share the sending queue In this way, the SUPERVLAN with large traffic may seize the queue bandwidth of the SUPERVLAN with small traffic to send to the CPU, and the SUPERVLAN with small traffic may be discarded because the queue is full, so the CPU will not be able to re-ARP because it cannot receive the uploaded message. learning, causing network anomalies

Embodiment Construction

[0026] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] A kind of SUPERVLAN of the embodiment of the present invention sets and sends the method for queue comprising:

[0028] Divide the SUPERVLAN sending CPU channel into multiple queues, and each queue corresponds to a SUPERVLAN;

[0029] The uploaded message is sent to its corresponding queue according to the SUPERVLAN information of the sent message.

[0030] When dividing the SUPERVLAN sending CPU channel into several queues, the correspondence between each queue and SUPERVLAN is: the queue number corresponds to the SUPERVLAN number, for example, SUPERVLAN1 corresponds to queue 1, SUPERVLAN2 corresponds to queue 2, ..., in order analogy.

[0031] When the message is sent to the CPU, it carries SUPERVLAN information, such as the SUPERVLAN number. When entering the queue, each SUPERVLAN number is mapped to a queue, and diff...

Abstract

The invention discloses a method and a device for forwarding SUPERVLAN messages, which comprises: dividing a central processing unit (CPU) channel for transmitting the SUPERVALN forwarded messages into a plurality of queues, wherein each queue corresponds to a SUPERVALN; and according to the SUPERVLAN information carried by the forwarded messages, forwarding the forwarded messages to corresponding queues. The method and the device can protect the CPU from being impacted, and ensure that the forwarded message of each SUPERVLAN can be processed by a CUP, that the forwarded messages of the SUPERVLANs do not interfere with one another and that the high-flow SUPERVLAN forwarded messages do not occupy the space of the low-flow SUPERVLAN forwarded message queues, nor prevent the low-flow SUPERVLAN forwarded message from being processed and learning successfully so as not to cause network to be abnormal; therefore the stability of the network is guaranteed to a greater extent.

Description

technical field [0001] The invention relates to network communication technology, more specifically, a method and device for sending hypervirtual local area network messages. Background technique [0002] Super virtual local area network SUPERVLAN is also called VLAN aggregation. This technology binds multiple sub-interfaces or real interfaces into a virtual interface, that is, a SUPERVLAN interface. Each sub-interface or real interface is called a sub-VLAN of this SUPERVLAN. [0003] This technology can make the hosts belonging to different broadcast domains in the same physical device be in the same IPV4 subnet, and use the same default gateway, which can eliminate the need to use the original IP address in a VLAN or MAN. One dedicated IP subnet limit. [0004] Using this mechanism can significantly reduce the consumption of IP address space in VLANs or MANs, solve the problem of insufficient buffered IP addresses, and improve the use efficiency of IP addresses. In addit...
