Problems solved by technology

Of course, uplink QoS can well solve the situation of limited uplink bandwidth, such as ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line) uplink gateway guarantees high-priority services in the case of uplinking multiple services, but with With the diversified development of home network services, especially the popularity of IPTV (Internet Protocol Television, interactive Internet TV) and P2P downloading services that have high requirements for downlink network traffic, only uplink QoS can no longer meet the needs of users in actual use of network services. experiences and feelings
For example, since the downlink traffic of P2P download and IPTV is very large, if the user is watching IPTV and downloading P2P at the same time, then the picture of IPTV will be discontinuous and briefly interrupted. Without the downlink QoS function, users can only choose to stop the current download service, or manually reduce the download traffic on the download software, but it is difficult for users to evaluate how much the download traffic should be reduced
Therefore, when the existing home gateway is used, when the network bandwidth is not enough, it either cannot take care of all the services at the same time, or although it takes into account all the services, it cannot guarantee that the network resources are fully utilized
In addition, for operators, in the specific case of network congestion, only using the downlink QoS function of the home gateway cannot quickly improve the situation of network congestion

[0033] The first embodiment of the present invention, such as figure 1 As shown, a method for a home gateway to implement downlink Qos includes the following specific steps:

[0034] Step 1: The network manager sends a command to the management media configuration interface of the home gateway to obtain the current downlink QoS configuration policy in the home gateway.

[0035] Step 2: The management media configuration interface sends the command to the QoS configuration management module, and the QoS configuration management module obtains the current downlink QoS configuration policy from the database, and returns it to the network management through the management media configuration interface. Since the present invention provides three downlink Qos configuration strategies for the network management, each kind of downlink Qos configuration strategy can realize the downlink Qos function, on this basis, the network management can also be flexible according to the current ne...

[0056] In the second embodiment of the present invention, a method for a home gateway to implement downlink Qos is roughly the same as the method in the first embodiment, the difference is that step 5 uses a resource restriction policy with high priority guarantees, specifically, as Figure 4 As shown in , the process for the resource restriction policy corresponding to the configuration to take effect in real time is as follows:

[0057] Step a3. The resource limit sub-module sets the priority of the business according to the business type. The business with the highest priority is usually a key business that affects user experience and feeling, and then allocates memory space for storing data packets for the data flow of the lowest priority business The upper limit of the number; in this embodiment, the resource restriction strategy of high priority guarantee is adopted, which is usually suitable for the networking situation with more business types in the network. If the mem...

[0068] In the fourth embodiment of the present invention, a system in which a home gateway implements downlink Qos is roughly the same as the system in the third embodiment, the difference lies in that the resource restriction sub-module implements resource restriction in a different manner, specifically,

[0069] The resource limitation sub-module is used to set the priority of the business according to the business type, and then allocate the upper limit of the memory space for storing data packets for the data flow of the lowest priority business; when receiving the data packet, according to the business type of the data packet Determine whether there is any memory space that can be allocated, if so, add one to the number of allocated memory space of the service type, otherwise discard the data packet; when releasing the data packet, allocate the memory space The number of spaces is reduced by one.

Abstract

The invention discloses a method and a system for realizing downlink Qos (Quality of Service) of family gateway, which provides a plurality of downlink Qos configuration strategy and configuration interface of managing media for network management, therefore the network management can adjust the current downlink Qos configuration strategy through the configuration strategy of managing media according to networking condition of current network, and enables the post-adjustment downlink Qos configuration strategy through a Qos configuration management module. When the data flow overloads or network congestion occurs, according to the technical scheme of the invention, the downlink Qos configuration strategy is executed, which can guarantee quality of critical service effectively, improve use experience of users, and simultaneously improve state of network congestion.

Description

technical field [0001] The present invention relates to the field of Internet application technology, and in particular to a method and system for communication equipment to realize downlink Qos (Quality of Service, quality of service). Background technique [0002] With the continuous development of the Internet and its application technology, people can use the Internet to enjoy more and more abundant service types, and communication equipment also integrates more and more abundant network application services. Taking the home gateway as an example, it serves as a home user The portal to access the Internet, in addition to providing users with basic Internet access services, also provides services such as network video, network telephony, and video surveillance. The Internet service can be subdivided into multiple sub-services such as web page browsing and P2P (peer to peer, end-to-end) downloading. Therefore, it can be expected that with the continuous development of hom...
