Example Embodiment

[0032] The core idea of ​​the present invention is that in the current IP network nodes, multiple scheduling algorithms are often needed to achieve QoS of the service, and the support for the scheduling algorithm is basically a condition of independent support, and the overall scheduling realization is not good. There is often a disorder. In view of the above problems, the present invention configures corresponding parameters for the queue, determines the scheduling mode of the queue according to the configuration parameters, and then determines the priority of the data packet according to the parameter characteristics of each data packet, thereby determining the queue to which the data packet should belong; Put it into the active queue linked list, and then allocate bandwidth resources for these queues according to the queue attributes in the active queue linked list, and schedule the data packets in the queues according to the allocated resources. The present invention realizes ...

Abstract

The invention discloses a queue scheduling method, which relates to the queue scheduling technique and is proposed to improve the unreasonableness of the current scheduling when a plurality of queues are converged. The adopted technical proposal is as follows: A. a data packet queue is configured with parameters to determine a scheduling mode of the queue; B. the characteristics of the data packet are extracted, and according to the characteristics, the property of the queue which the data packet belongs to is determined, and the data packet is fallen under the queue corresponding to the property of the queue, and then the queue is arranged into an active queue link table according to the priorities; C. the activity queue link table is configured with resources according to the queue properties and the queue priorities and then the queue is scheduled according to the resources configured. The invention fully takes all kinds of application scenes into consideration, which can better converge a plurality of scheduling algorithms. The same program codes in all the scheduling algorithms are omitted when realizing, which is convenient for development and maintenance.

Description

technical field [0001] The invention relates to queue scheduling technology, in particular to a mixed queue scheduling method based on deficit weighted round robin (DWRR, Deficit Weighted Round Robin) and strict priority (SP, Strict Priority). Background technique [0002] The existing IP network provides Internet, Intranet, and Extranet connections. With the development of network technology, the types of services provided by the IP network are also increasing. These services include aggregation services, transmission services, and voice services. Ingress servers, such as narrowband access servers and broadband access servers, aggregate the service flows of non-persistent connection users and send them to Internet access providers or Internet content providers. Transport services transmit services between persistently connected users of the IP network or pass their services to sites directly connected to the Internet. Voice services include call waiting, service group IP, ...
