Problems solved by technology

[0003] As the network scale expands, network devices will carry more traffic forwarding, which may exceed the bandwidth limit of the physical interface and cause congestion, and the switching chip cannot send reports to the forwarding chip connected to the physical interface through the interconnection interface arts
At this time, the packets congested on the switch chip cannot be matched with the QOS rules through the physical interface, and the QOS rules configured by the user for the physical interface become invalid. As a result, some important packets are discarded by the switch chip, reducing the network equipment forwarding rate. Reliability of text

Abstract

The invention provides a rule issuing method and device and network equipment, and is applied to the technical field of communication equipment. The rule issuing method comprises the steps of receiving a QOS configuration instruction, and obtaining a QOS rule applied to a target physical interface; issuing the QOS rule to a forwarding chip connected with the target physical interface; and issuingthe QOS rule to a switching chip corresponding to the target physical interface, so that the switching chip schedules the message issuing the target physical interface based on the QOS rule. EffectiveQOS rule pre-scheduling on the physical interface is realized through the switch chip, the condition that QOS scheduling of the physical interface cannot be realized under the congestion condition isavoided, and the reliability of network equipment is improved.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular to a method, device and network equipment for issuing rules. Background technique [0002] A switching chip is provided in the network device, and the switching chip is connected to multiple forwarding chips. Among them, the switching chip and the forwarding chip are connected through the interconnection interface, and the forwarding chip is connected to the physical interface of the network device. When the switching chip receives the message, it will send the message to multiple forwarding chips through the interconnection interface. The user can configure QOS (Quality of Service, quality of service) rules on the physical interface, so as to ensure that important packets (for example, protocol packets) can be forwarded preferentially. [0003] As the network scale expands, network devices will carry more traffic forwarding, which may exceed the bandwidth limit o...
