Problems solved by technology

[0004] The inventor found in the research process that the multi-level QoS queue scheduling algorithm in the prior art needs to perform multiple differentiated scheduling on the data packets with the same number of dimensions, so the scheduling performance is reduced compared with the single-level QoS

Abstract

The present invention provides a priority dispatching method and device, and a firewall. The method comprises the steps of: calculating the priorities of received data packets according to a mapping mode from multi-level Qos to a single-level Qos; searching priority positions corresponding to the priorities of data packets from a single chain table, wherein the single chain table comprises a plurality of priority positions, and each priority position corresponds at least one data stream queue; and inserting the data packets into the data stream queues in the corresponding priority positions inthe single chain table according to the data streams to which the data packets belong. According to the embodiment of the invention, the multi-level dispatching of the data packets can be achieve forone time, and the performances of the multi-level Qos can be ensured. When the data packets are sent, it is ensured that the data packets with high priorities are preferentially sent and the sendingfairness between the data with the same priority can be ensured according to the principle of the data packets with high priorities being preferentially sent and the mode of the data packets with thesame priority being sent.

Description

Technical field [0001] This application relates to the field of QoS technology, and in particular to a priority scheduling method, priority scheduling device and firewall. Background technique [0002] QoS (Quality of Service) means that when network congestion occurs, network devices (such as firewalls) divide data packets into different priorities, and submit them to different priority queues according to the different priorities, and then pass Queue scheduling algorithm to process different data packets. [0003] Single-level QoS refers to scheduling according to one of the attributes of the data packet. If you want to perform comprehensive priority scheduling on the data packet from multiple attributes, for example, multiple users, multiple services, multiple flows, etc. For unified management and hierarchical scheduling, a multi-level QoS queue scheduling algorithm is required. [0004] During the research process, the inventor discovered that the multi-level QoS queue schedul...
