Problems solved by technology

[0011] 1. The QoS policy is statically configured or the frequency of change is very low, while the network situation is dynamically changing, which cannot guarantee the quality of real-time services
[0012] 2. In a network with NAT, the address of the front-end device or client changes dynamically. At this time, it is not feasible to set the packet priority or reserve bandwidth for a certain address.
[0013] 3. All customers share bandwidth fairly, and it is impossible to guarantee differentiated services for customers of different levels
A workaround is to use the target address as a policy deployment parameter, but this limits the mobility of the client and seriously affects the development of the business
[0015] 4. Implement QoS policies for each business separately. Due to the superposition effect of multiple services, the QoS policies of various services may conflict with each other, and the effect is difficult to predict.
Even if the best plan is found and implemented based on the long-term historical analysis of the business, because each business is not balanced at different times, the compromise plan is obviously a compromise of various businesses, and none of them are optimal.
Moreover, this probabilistic guarantee does not meet the customer's demand for a constant minimum quality

Embodiment 2

[0101] Embodiment 2. This embodiment ensures the QoS of the video stream by simultaneously monitoring the quality of the video stream sent by the front-end device to the media distribution server and received by the client.

[0102] In this embodiment, the process of monitoring the quality of the video stream sent by the front-end device to the media distribution server and adjusting the QoS according to the monitoring results is exactly the same as that of Embodiment 1, and will not be repeated here. Monitor the quality of the received video stream and adjust the QoS.

[0103] Fig. 5 is the QoS adjustment flowchart of the real-time service provided by Embodiment 2 of the present invention, as shown in Fig. 5, its specific steps are as follows:

[0104] Step 501: The client configures video stream quality classification rules.

[0105] The video stream quality classification rule configured on the client is the same as that configured on the media distribution server in step ...

Embodiment 3

[0134] Embodiment 3 In this embodiment, the QoS of the video stream is guaranteed by monitoring the quality of the video stream sent from the AG of the front-end device to the media distribution server.

[0135] FIG. 6 is a flow chart of QoS adjustment for real-time services provided by Embodiment 3 of the present invention. As shown in FIG. 6 , the specific steps are as follows:

[0136] Step 601: The media distribution server configures video stream quality level classification rules.

[0137] This step is the same as step 301.

[0138] Step 602: The CMS sets the minimum video stream quality for customers of different levels, and configures it to the media distribution server.

[0139] This step is the same as step 302.

[0140] Step 603: The media distribution server receives the video stream from the AG of the front-end device, and determines the quality level of the video stream.

[0141] The media distribution server may set a video stream quality monitoring period T,...

Embodiment 4

[0160] Embodiment 4 In this embodiment, the QoS of the video stream is guaranteed by monitoring the quality of the video stream sent by the AG of the client.

[0161] FIG. 7 is a flow chart of QoS adjustment for real-time services provided by Embodiment 4 of the present invention. As shown in FIG. 7 , the specific steps are as follows:

[0162] Step 701: The client configures video stream quality classification rules.

[0163] In this step, the video stream quality classification rules configured on the client are the same as those in step 401.

[0164] Step 702: The client receives the video stream, determines the quality level of the video stream, carries the video stream quality level and the client ID in the video stream quality report, and sends it to the media distribution server through the client's AG.

[0165] Step 703: The media distribution server receives the video stream quality report, determines the AG ID corresponding to the client ID in the report, and saves ...

Abstract

The invention discloses a service quality adjustment method and a device for real-time services. The method includes the following steps: monitoring the quality of transferred media stream; driving at least one device in the transmission direction to reduce the transmission bandwidth of media stream if the media stream quality is lower than the reset QoS requirements; and / or driving at least one device in the transmission direction to increase the transmission bandwidth of media stream if the media stream quality is higher than the reset QoS requirements. The method guarantees the dynamic adjustment of the QoS and divides the clients into different levels; if the quality of the highest-level client cannot be guaranteed, the lowest-level client will be closed, thus ensuring that the clients of different levels can get corresponding service quality.

Description

technical field [0001] The present invention relates to the technical field of business services, in particular to a method and device for adjusting the quality of service (QoS, Quality of Service) of real-time business. Background technique [0002] With the rapid development of computer network technology, operators provide customers with more and more real-time services, and continuously provide assistance for the upgrading of their own services. In recent years, not only voice services represented by Voice over IP (VoIP, Voice over IP) have been widely used, but also video services such as video conferencing and remote monitoring have been continuously promoted and applied. On the one hand, for individual and enterprise customers, the real-time service provided by the operator is low in cost, and there is no manpower requirement for maintenance; [0003] However, for operators, how to better meet and treat customers' business needs differently, formulate reasonable pric...
