Description
Technical Field
The invention belongs to the technical field of internet, and particularly relates to a flow fine scheduling system.
Background
Currently, network users usually obtain an IP address through an Internet Service Provider (ISP) and access the internet while enjoying network services. Different ISPs are split into different layers according to the sizes of the ISPs, the trunk ISP is the most wide in coverage area, usually in a national level range, the next area is the region, one or more trunks are connected in parallel, and finally the local ISP can be directly connected with the trunks or the region. However, with the rapid development of the number of users, the number of backbone ISPs is limited, so that the backbone ISPs need to cover an excessively large amount of network data traffic, even if the backbone ISPs have the largest bandwidth, traffic exchange can be completed, but the transmission speed is slower as the distance is longer, and especially when traffic forwarding is performed in an adjacent area, the traffic needs to be forwarded to a place beyond kilometers, which causes waste of network resources, increases the time length of traffic forwarding, and affects the experience of network users.
In order to solve the problems, a mode of constructing an internet Exchange point IXP (internet Exchange point) for fast forwarding in an area is provided, and by constructing the IXP in the area, traffic forwarding can be completed without a backbone ISP when user traffic is forwarded, so that network delay is greatly reduced, traffic forwarded to the backbone ISP is saved, and traffic use cost is reduced.
However, in the above manner, when traffic forwarding frequently used by a network user needs to pass, the traffic forwarding needs to pass through a backbone ISP, which affects user experience; meanwhile, the Internet exchange point (IXP) is difficult to construct and popularize in the region.

Example 1
The embodiment provides a technical scheme: a flow fine scheduling system comprises a user terminal, a scheduling center and a content supply terminal;
the dispatching center is used for receiving the user end requirement and dispatching the content in the content supply end according to the requirement;
a fast forwarding channel and a comprehensive forwarding channel are arranged in the content supply end;
an analysis module, a scheduling module and a construction module are arranged in the scheduling center;
the analysis module is used for analyzing the traffic use habits of the user side;
the scheduling module is used for calling and selecting a fast forwarding channel or a comprehensive forwarding channel according to a single user traffic request to forward traffic;
and the construction module is used for constructing a corresponding fast forwarding channel according to the result of the analysis module to form a fast forwarding content library.
In the operation process, the user side obtains network services by connecting with the dispatching center, and the content supply side is used for providing network contents including pictures, audio, images and the like for the user side. Wherein a fast forwarding channel and a comprehensive forwarding channel are arranged in the content supply terminal; the comprehensive forwarding channel is connected with three operators (communication, telecommunication and mobile) and used for acquiring network contents in the three operators, the three operators in China contain most of network contents and access a large number of content providers, so that the comprehensive forwarding channel has the advantage of comprehensive network content service, but when the comprehensive forwarding channel forwards traffic, corresponding network contents need to be matched with the massive content providers of the three operators, the service range of the three operators usually covers the national area, and therefore when the traffic is forwarded, the traffic is often forwarded to the place beyond thousand miles, the waste of network resources is caused, the traffic forwarding time is prolonged, and the experience of network users is influenced.
According to the 2/8 principle, the content providers frequently accessed by the user terminal are often concentrated in a small part, so the analysis module is used to obtain the traffic usage habit of the user terminal, the construction module is used to additionally construct the fast forwarding channel in the content provider terminal and form the fast forwarding content library, when the user terminal needs to access the network content, the scheduling center firstly judges whether the network content belongs to the network content in the fast forwarding content library, and when the network content belongs to the network content, the scheduling center quickly matches the corresponding content provider through the fast forwarding channel and fast forwards the corresponding network content, thereby greatly improving the efficiency of traffic forwarding, reducing the delay of network forwarding and reducing the traffic waste during network forwarding.
In a preferred scheme, the analysis module is provided with a traffic capture unit and an analysis unit, the traffic capture unit is used for capturing traffic data flowing through the scheduling center at a user side in real time, and the traffic data comprises traffic size, a traffic use time period and a content provider corresponding to the traffic; in order to avoid invading the network use privacy of a single user and improve the analysis efficiency, the flow capturing unit acquires flow data by taking a certain number of user groups as units; the user groups may be classified in units of the same cell, the same region, the same network service provider, or the like.
The analysis unit is used for sorting the traffic data to generate different content provider traffic ratio tables and different content provider traffic use time tables. The different content provider traffic ratio table is used for reflecting a plurality of content providers most frequently accessed by the user terminal, and the different content provider traffic usage schedule is used for reflecting time habits when the user terminal accesses different content providers.
In a preferred embodiment, the building process of the building block is as follows:
acquiring traffic proportion tables and traffic use time tables of different content providers, and calculating traffic proportion values and use time of different content providers;
marking the content providers with the flow rate ratio and the use duration exceeding the set value as high-frequency content providers, and generating a high-frequency content provider construction table;
generating a supply benefit value according to the flow supply size and the supply duration of the high-frequency content provider; the calculation process of the supply benefit value is as follows:
1) multiplying the flow supply size by a flow coefficient, adding the supply duration time by a duration coefficient to obtain a reference value, wherein the flow coefficient is 0.5-0.8, and the duration coefficient is 0.2-0.5;
2) and multiplying the reference value by an efficiency coefficient to obtain the supply efficiency value.
The benefit coefficient may be set to a fixed value, or obtained by taking a ratio of a highest value of the construction cost value and a highest value of the reference value.
And acquiring a construction cost value of the fast forwarding channel of the high-frequency content provider, and constructing the fast forwarding channel of the high-frequency content provider when the construction cost value is lower than the supply benefit value. Otherwise, the fast forwarding channel of the high-frequency content provider is not constructed temporarily; the fast forwarding channel is constructed by making an agreement with the content provider to obtain the license of the content provider, and communicating the server of the content provider with the fast forwarding channel, so the construction cost value includes the license cost, the construction cost and the operation and maintenance cost which may be generated.
In the preferred scheme, the user terminals are divided according to a set region, and the scheduling center analyzes and schedules the whole user terminals in the same region. The set region division is used for carrying out overall analysis on the user terminals in the set region, and the network use habits of different regions often have great difference, for example, the user terminal use habits of rural areas and urban areas have great difference, and the user terminal use habits of southern areas and northern areas have great difference; and the user terminals in the same area often have highly coincident network use habits, so that the user terminals are divided according to the set area, the use habits of the user terminals can be more accurately analyzed, the network flow is more accurately scheduled, and the use experience of the user terminals is improved. Secondly, the cost of the hardware of the system built in the equipment can be reduced by adopting a mode of dividing a set area; finally, the building module is facilitated to set corresponding fast forwarding channels in the same area, the length of the fast forwarding channels in network forwarding in the area is reduced, the network forwarding delay of the fast forwarding channels is reduced, and the use experience of a user side is improved.
In a preferred embodiment, the fast forwarding channel is configured to connect to a plurality of content providers, and is connected to a dynamic adjustment module, where the dynamic adjustment module is configured to dynamically adjust a communication state between the fast forwarding channel and the content providers. Because the construction and the release of the fast forwarding channel have long hysteresis, when the use habit of the user side obviously changes, the construction and the release of the fast forwarding channel often cannot be adjusted in time, and the dynamic adjustment module can adjust the communication state between the fast forwarding channel and a content provider in real time according to the change of the use habit of the user side or the change of the traffic forwarding quality of the fast forwarding channel, thereby being beneficial to ensuring the stability of network activities of users and improving the network experience of users.

the first quality monitoring unit and the second quality monitoring unit are both connected with the control unit;
when the forwarding quality of the content provided by the same content provider through the comprehensive forwarding channel is higher than that through the fast forwarding channel, the control unit marks the content provider as a dormant provider.
In a preferred scheme, the control mode of the control unit is as follows:
1) acquiring the size and duration of flow forwarding performed by different content providers through the fast forwarding channel;
2) identifying the content provider with the flow forwarding size and the flow forwarding duration exceeding the highest set value as an active provider, and identifying the content provider with the flow forwarding size and the flow forwarding duration being lower than the lowest set value as a dormant provider;
