Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] figure 2 It is a flowchart of a bandwidth allocation method according to an embodiment of the present invention. Such as figure 2 As shown, the method may include the following processing steps:

[0026] Step S202: the child node receives the first bandwidth allocated by the parent node for the child node, wherein the first bandwidth is allocated by the parent node according to the weight value of the child node;

[0027] Step S204: the child node allocates the first bandwidth according to the weight value of each node in one or more nodes attached to the child node.

[0028] In related technologies, the basic WFQ scheduling model cannot be applied to HQOS services. use as figure 2 In...

Abstract

The invention discloses a method and a system for bandwidth distribution. According to the method, child nodes accept first bandwidths which are distributed for the child nodes by a father child, wherein the first bandwidths are distributed by the father node according to the weighted values of the child nodes, and the child nodes distribute the first bandwidths according to the weighted value of each node of one or a plurality of nodes of the child nodes. The technical scheme is applicable to weighted fair queuing (WFQ) scheduling on multilevel and multi-service scenes and provides the flexible method for the bandwidth distribution for the multilevel and multi-service scenes.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a bandwidth allocation method and system. Background technique [0002] In the field of communications, Weighted Average Queuing (Weight Fair Queue, referred to as WFQ) is a weight-based fair queue scheduling, which is widely used in Quality of Service (QOS for short) and Hierarchy Quality of Service (Hierarchy Quality of Service, referred to as HQOS for short), provides various scheduling models. figure 1 is a schematic diagram of a basic WFQ scheduling model according to the related art. Such as figure 1 As shown, the parent node is a scheduling node, which allocates corresponding bandwidth to the child nodes according to different weight values ​​of each child node. The specific bandwidth allocation algorithm can be implemented in different ways, among which, the most commonly used way is: the bandwidth ratio of m nodes is Wm / (W0+W1+...+Wm+...+Wn). For QOS, the parent no...
