Method and device for controlling message to be uploaded to CPU (central processing unit)

Abstract

The invention discloses a control method for uploading a message to a CPU (Central Processing Unit), the method is applied to switching equipment comprising a hardware strategy module and a software strategy module, and the method comprises the following steps: the software strategy module carries out initialization configuration on the hardware strategy module; the hardware strategy module performs feature matching on a first message to be sent, and determines a first TRAP CODE and a first VOQ group of trap resources corresponding to the first message; determining a first VOQ unit in a VOQ group corresponding to the to-be-sent message according to a first service classification COS mark of the first message and a corresponding relationship between a preset service classification COS mark and each VOQ unit in the VOQ group; and uploading a first message carrying the first COS mark and the message type to a CPU (Central Processing Unit) through the first TRAP CODE and the first VOQ unit according to an initially configured message strategy corresponding to the first VOQ unit. According to the embodiment of the invention, the problem of how to effectively utilize trap resources when the message is uploaded to the CPU in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a control method and device for sending a message to a central processing unit (Central Processing Unit, CPU). Background technique [0002] When an existing switching device sends a packet to the CPU, it usually needs to use hardware trap resources to send the packet, and a packet type first needs to be associated with a trap resource, that is, a trap CODE. A trap CODE refers to A kind of hardware resource ID used by the CPU when the message is sent. You can set the corresponding resource ID on the CPU port according to the requirement. When the message is sent to the CPU, it will carry the resource ID used by the CPU according to the setting; The virtual output queue (VirtualOutput Queue, VOQ) group is bound, the priority scheduling and speed limit are performed through VOQ scheduling management, and then it is associated with the hardware port resource GPORT connect...
