[0050] Structure of the QoS Framework

[0051] The network is divided into three layers: including QoS-related business layer, resource control layer and bearer layer; the resource control layer is divided into two sub-layers: coarse-grained resource control layer and fine-grained resource control layer. QoS logical frame structure such as figure 1 shown.

[0052]A QoS pipe refers to a virtual connection that connects two boundaries of a network with certain QoS parameter characteristics. Its characteristics are: it is end-to-end; QoS pipeline resources can be adjusted; QOS pipeline establishment is coarse-grained resource allocation, such as each QoS pipeline is used to transmit a certain service or A QoS class. The QoS pipeline is edge-to-edge in a network. For a large network, it can be divided into several domains. In each domain, the QoS pipeline is edge-to-edge. The establishment of QoS pipeline is based on network traffic forecast and capacity planning, and there ar...

Abstract

The present invention discloses a system for ensuring network quality of service(QoS), comprising: a QoS service controller (QSC) for extracting QoS request to network from service request, transmitting the QoS request to a DRC resource controller in the network, and transmitting resource-releasing information; a QoS pipe provisioning controller (QPPC) for provisioning pipes, obtaining information about the resource occupation condition of Qo5 pipes periodically, and adjusting the capacity of the pipes dynamically but not by real-time; a distributed resource controller (DRC) for processing the QoS request from the QSC dynamically, and implementing access control and resource distribution of each resource request. Based on this system, the invention also provides a method for distributing network resource in a layered way.
