In this bandwidth management mode, the administrator only specifies in advance that the service feature is VoIP, but cannot clearly describe the flow features of the 100 VoIP sessions, that is, which IP quintuple (source IP address, source IP address) the VoIP session belongs to port number, destination IP address, destination port number, and protocol number), whether it belongs to the same VoIP session as other VoIP service flows
[0008] It can be seen that the existing bandwidth management methods cannot ensure automatic, accurate and efficient bandwidth allocation

Embodiment Construction
[0030] The principle of the dynamic bandwidth segmentation method proposed by the present invention is as follows:
[0031] Multiple sending channels corresponding to multiple types of applications (also referred to as services) are established, and the bandwidth of each sending channel (total channel) is specified for sending applications or services of the same type.
[0032] Each sending channel (total channel) includes multiple sending sub-channels for sending the same flow (also referred to as a session), and the bandwidth of each sending sub-channel is specified.
[0033] Such as image 3 As shown, the bandwidth management method supporting dynamic bandwidth segmentation of the present invention includes:
[0034] Step 1: identify the service type of the message of the input data stream, and send the message into the transmission channel corresponding to the identified service type;
[0035] Step 2: Identify the flow identifier (ie flow ID) of the message in the sendin...

The present invention provides a bandwidth management method and device supporting dynamic bandwidth segmentation, which can automatically perform flow identification on the basis of application or service identification, and allocate appropriate bandwidth to each flow on the basis of flow identification. The bandwidth management method supporting dynamic bandwidth segmentation according to the present invention includes the following steps: identifying the service type of the message of the input data flow, sending the message into the transmission channel corresponding to the identified service type; identifying in the transmission channel The flow identifier of the message; if the flow identifier of the message is identified, the message is sent to the sending sub-channel corresponding to the identified flow identifier, thereby scheduling and sending the message; if the flow of the message is If the identifier is not recognized, access to the input data stream is refused. The bandwidth management method and device supporting dynamic bandwidth division of the present invention can be applied to routers, or other devices with routing functions, or devices with only bandwidth management functions.
Description
technical field [0001] The invention relates to a bandwidth management method, in particular to a bandwidth management method and device supporting dynamic bandwidth division. Background technique [0002] The main function of bandwidth management is to provide guaranteed transmission performance for delay-sensitive services such as VoIP (Voice over IP), interactive gaming (interactive games) or VoD (Video-On-Demand, video on demand). The most effective way to ensure transmission performance is to provide sufficient bandwidth for upper-layer applications or services. Therefore, QoS (Quality of Service Guarantee) is changing from traditional "congestion management" to a more effective and targeted "bandwidth management" . [0003] The main application scenarios of bandwidth management are as follows: figure 1 As shown, the outbound interface direction of the router is often prone to bandwidth competition. In order to ensure that the flow of a specified application or servic...
