Device for realizing hierarchical quality of service business and method

Abstract

The invention discloses a device for realizing hierarchical quality of service business, comprising an information receiving module used for receiving types of business and business process information, an information distribution module used for determining an object business tree according to the received types of business and business process information and storing the received types of business into a node to be processed of the object business tree, and a business management module used for traversing the object business tree and conducting the corresponding operations on the marked nodes in the traversing process. The invention also discloses a method for realizing the hierarchical quality of service business, comprising: the business management module is used for traversing the object business tree and conducting the corresponding operations on the marked nodes in the traversing process. By adopting the device and the method, the repetitiveness of software codes for realizing HQOS business can be reduced, and the maintainability and the expandability of the software code are improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a device and method for realizing Hierarchical Quality of Service (HQOS, Hierarchical Quality of Service) services. Background technique [0002] HQOS technology realizes the bandwidth guarantee of multi-user and multi-service under the differentiated service (Diff-Serv) model through hierarchical scheduling. The structure of the HQOS service tree is as follows: figure 1 As shown, there are four layers including port layer, user group layer, user layer, and service layer. After the HQOS service tree is bound to the application port, the HQOS service tree can reflect the tree of the subnet connected to the network through the application port. Based on the hierarchical topology and service forwarding path, the packets of the subnet can be scheduled hierarchically through the HQOS service tree to implement functions such as congestion avoidance, multi-level scheduling, traffi...

AI Technical Summary

Problems solved by technology

[0012] Each HQOS service is implemented by a corresponding independent service resource management module, but part of the implementation process of various HQOS services is similar, so that some functions of different service resource management modules are similar, such as: binding module, unbinding module, subtree Both the adding module and the subtree deleting module need to call the traversal tree function multiple times and maintain the traversal position. Both the binding module and the subtree adding module need to apply for and allocate resources for the node, and the unbinding module and the subtree deleting module need to be executed. In order to release the operation of node resources, etc., in this way, there are a lot of repeated codes in the software codes of each business resource management module, which increases the complexity of the code and the difficulty of maintaining the code, and the efficiency of processing the HQOS business is low.
