Embodiment Construction

[0021] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] figure 2 It is a flowchart of a bandwidth allocation method for a DiffServ network according to an embodiment of the present invention. Such as figure 2 As shown, the method includes steps 201-206.

[0023] In step 201, network traffic is divided into multiple aggregation classes.

[0024] Specifically, the edge router puts corresponding labels on the data packets according to different service levels, and divides the network traffic into multiple aggregation classes.

[0025] Table 1 shows the 8 bits of the ToS field, where DSCP (Differentiated Services Code Point, differentiated services code point), CU (Currently Unused, not currently used). In the DiffServ network, the first 6 bits of the ToS field are used to mark the data packet, and the aggregation class is divided by marking different values. The r...

Abstract

The invention relates to a bandwidth allocation method of a differentiated services architecture network. The method comprises the following steps: dividing the network traffic into a plurality of aggregation classes; calculating the bandwidth ratio and the queue increment ratio of the plurality of aggregation classes; class traffic load; calculate the traffic load ratio according to the traffic load; obtain the bandwidth of the aggregation class according to the traffic load ratio and weight parameters; obtain the target bandwidth size of multiple aggregation classes according to the bandwidth. The implementation method of the invention is simple and efficient, has extremely short response time, and does not introduce any unstable factors to the network.

Description

technical field [0001] The invention relates to computer network management technology, in particular to a bandwidth allocation method of a differentiated services architecture network. Background technique [0002] With the expansion of the scale of the Internet and the increase in the types of bearer services, especially the emerging services with real-time service quality requirements (such as VoIP, video conferencing, live video, etc.), the communication network is required to provide efficient end-to-end QoS (Quality of Services, quality of service) support gradually increased. In order to meet the needs of business development and guarantee the QoS of services, IETF (Internet Engineering Task Force, Internet Engineering Task Force) proposed IntServ (Integrated Services, integrated service architecture) and DiffServ (Differentiated Services, differentiated Service architecture) two network technologies to guarantee QoS. [0003] While RSVP (Resource Reservation, resou...
