Embodiment 1

[0036] The bandwidth control method provided in Embodiment 1 is applied to routing and switching devices including multiple interfaces, such as routers and gateway devices; please refer to Figure 2, including the following steps:

[0037] S1-1. Divide the interface into domains according to the physical networking structure, wherein any domain includes a group of internal interfaces and a group of external interfaces, and the number of interfaces in each group is at least one;

[0038] The so-called interface (interface) usually refers to a physical interface, such as a network interface of a router or a switch, which can provide a bandwidth of 100Mbps or 1Gbps.

[0039] In this step, the interface is divided into segments according to the physical networking structure. For example, when the physical networking structure is that enterprise intranet a and enterprise intranet b are connected to the Internet network through a routing and switching device, two domains can be creat...

Embodiment 2

[0058] Please refer to Fig. 4, present embodiment 2 comprises the following steps:

[0059] S2-1. Divide the interface into domains according to the physical networking structure, wherein any domain includes a group of internal interfaces and a group of external interfaces, and the number of interfaces in each group is at least one;

[0060] S2-2. Divide the interface pipelines for the interfaces, and set each interface pipeline to correspond to an application;

[0061] Generally, an interface can be divided into multiple interface pipelines (pipelines), each interface pipeline can have a different bandwidth, and the sum of the bandwidths of the interface pipelines is the interface bandwidth.

[0062] When each interface pipe is created, it can be used to correspond to different applications, such as peer-to-peer (P2P for short), Voice over Internet Protocol (VoIP for short), and so on. Wherein, the interface pipeline is the transmission path of the corresponding application ...

Embodiment 3

[0075] In order to implement fine-grained bandwidth control, in this embodiment, setting the second allowable bandwidth according to the application information may include: setting the total number of allowed connections of an application, the new connection rate and / or connection bandwidth limit, and the like.

[0076] Then, referring to FIG. 6, step S2-6 in Embodiment 2 may specifically include:

[0077] S3-6-1. Identify whether the message is a new connection, if yes, execute step S3-6-2, otherwise execute S3-6-4;

[0078] S3-6-2. Identify whether the message exceeds the total number of allowed connections of the application, if yes, execute step S3-6-6, otherwise execute S3-6-3;

[0079] S3-6-3. Identify whether the message exceeds the new connection rate of the application, if yes, execute step S3-6-6, otherwise execute S3-6-4;

[0080] S3-6-4. Identify whether the message exceeds the connection bandwidth limit of the application, if yes, execute step S3-6-6, otherwise ...

Abstract

The utility model discloses a bandwidth control method and a device, which are used on a route switching device with a plurality of interfaces. The method is to field-divide the interfaces according to the physical network structure; wherein each field comprises a group of internal interfaces and a group of external interfaces and the number of the interfaces in each group is one or more; the field bandwidth strategy is established for each field; when the packet is received from an interface, the bandwidth is controlled according to the field bandwidth strategy in the affiliated field and then the packet passing through the bandwidth controlling process is sent to the other group of interfaces in the affiliated field. The utility model considers the interface hardware limiting factors and the logical managing factors sufficiently so as to get rid of the dependency on the single interface, ensure the bandwidth stability of the conversational individual and be propitious to realize the multilayer and fine-grain interface bandwidth control.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a bandwidth control method and a bandwidth control device. Background technique [0002] With the development of broadband network technology, how to effectively manage and control bandwidth to control the increasingly serious abuse and misuse of bandwidth, so as to improve the utilization of network resources, has always been a hot topic. [0003] At present, most of the bandwidth control solutions used in routers and switches adopt a flat bandwidth control solution based on the physical layer, that is, the forwarding traffic on an interface is the core, and the traffic entering the same interface is controlled according to Different indicators allocate different bandwidths, as shown in Figure 1: All traffic forwarded from the same interface is divided into different queues through the queue scheduling algorithm according to different indicators, and scheduled to b...
