  However, when using the DiffServ technology, it is necessary to set an appropriate communication quality class. In this setting, a method of setting a specific application having a large influence on the user's quality of experience to a high communication quality class has been the mainstream. This method works well when the communication provider and the application provider are the same, but when the communication provider and the application provider are different, a so-called “tragedy of common land” problem occurs, so correct control is difficult. There is a problem of becoming.

  In order to avoid the above-described problem, Patent Document 1 and Patent Document 2 refer to the port number of the packet on the network to determine the application. However, in recent years, traffic of a specific port number represented by TCP port 80 has become the majority, and priority control using a port number is becoming an unrealistic means.

  Therefore, there is a need for an apparatus that improves the quality of communication experienced by the user based on communication traffic instead of port numbers.

  An object of the present invention is to provide a communication priority setting apparatus, method, and program for improving communication traffic quality caused by a user terminal in a communication network and improving communication quality experienced by a user.

Current smartphones and PCs generate various types of traffic, which can be roughly divided into the following two types.
1. Foreground traffic: Communication traffic generated by user operations (Web page browsing, etc. by user operations)
2. Background traffic: Communication traffic generated regardless of user operations (automatic software update, etc.)
Among these, foreground traffic has a great influence on the user's quality of experience, so it is desirable to perform priority control. On the other hand, even if the background traffic is lowered in priority, it is considered that the influence on the user experience quality is slight. In the present invention, the user satisfaction is comprehensively improved by classifying traffic into two types and setting different priorities for each.
Specifically, the following solutions are provided.

Furthermore, the communication priority setting device 10 includes a content number acquisition unit 131, a server number acquisition unit 132, a periodicity analysis unit 133, and a load amount ratio acquisition unit 134. Hereinafter, each part will be described.

  The packet extraction unit 11 extracts communication traffic packets. Specifically, the packet extraction unit 11 inputs communication data, and extracts packets constituting the communication data based on the input communication data.

  The communication flow construction unit 12 constructs a communication traffic communication flow based on the packet information extracted by the packet extraction unit 11, and stores the communication flow in the communication flow storage unit 31 that stores the communication flow. Specifically, the communication flow construction unit 12 regards packets having common packet attributes (for example, transmission source / destination IP address, transmission source / destination port number, protocol number, etc.) as the same communication flow. As a single communication flow, the communication flow storage unit 31 stores the communication time together with the communication time. The communication time may be a time that can be regarded as the start time of the communication flow, for example.

  Based on the communication flow constructed by the communication flow construction unit 12, the traffic judgment unit 13 determines whether or not communication traffic has occurred based on a user operation at the user terminal. Specifically, the traffic determination unit 13 determines based on information from the content number acquisition unit 131, the server number acquisition unit 132, the periodicity analysis unit 133, and the load amount ratio acquisition unit 134.

The traffic determination unit 13 determines whether or not the number of contents acquired by the number-of-contents acquisition unit 131 is larger than a content number threshold. If it is determined that the number is large, communication traffic is generated based on a user operation. Judged as communication traffic.

  The server number acquisition unit 132 acquires the number of servers accessed by the user terminal and included in one communication flow based on the communication flow established by the communication flow construction unit 12. The traffic determination unit 13 determines whether or not the number of servers acquired by the server number acquisition unit 132 is larger than the server number threshold value. If it is determined that the number is large, communication traffic is generated based on a user operation. Judged as communication traffic.

The periodicity analysis unit 133 analyzes time series periodicity of the communication flow (for example, the communication flow start time and time interval are regular) based on the communication flow stored in the communication flow storage unit 31. To do. The traffic determination unit 13 determines whether or not the communication flow has periodicity by the periodicity analysis unit 133, and determines that the communication traffic is generated based on a user operation when it is determined that the communication flow has no periodicity. .
For example, the periodicity analysis unit 133 analyzes the communication time of the communication flow stored in the communication flow storage unit 31, and every fixed time (for example, every 0:00) or every time within a predetermined range from the fixed time (for example, Then, it is analyzed whether or not the communication is performed at every time that can be regarded as the same time within ± 15 minutes, such as the communication flow of 0: 5 and the communication flow of 0:13 on the next day. Further, the periodicity analysis unit 133 analyzes the time interval of the communication flow based on the communication time of the communication flow stored in the communication flow storage unit 31, and performs a periodic time interval (for example, every hour) or a predetermined time interval. Communication is performed at regular time intervals within the range (for example, every time interval that can be regarded as the same within ± 15 minutes, such as a communication flow after 55 minutes and a communication flow after 65 minutes). Analyzes whether or not.

  The load amount ratio acquisition unit 134 acquires the ratio between the upload data amount (UL) and the download data amount (DL) based on the communication flow constructed by the communication flow construction unit 12. The traffic determination unit 13 determines whether or not the ratio acquired by the load amount ratio acquisition unit 134 indicates a predetermined relationship. If the traffic determination unit 13 determines that the ratio indicates a predetermined relationship, the traffic determination unit 13 determines communication traffic based on a user operation. It is determined that the communication traffic has occurred. Specifically, the traffic determination unit 13 has a ratio of the upload data amount to the download data amount higher than a predetermined upload ratio (UL / DL> C), and a ratio of the download data amount to the upload data amount. Is higher than a predetermined download ratio (DL / UL> D), the communication traffic is determined to be communication traffic generated based on the user's operation.

  The traffic classification unit 14 classifies the communication traffic determined by the traffic determination unit 13 based on the user operation at the user terminal as the foreground traffic, and is not determined to be generated based on the user operation at the user terminal. Categorized communication traffic as background traffic.

The priority setting unit 15 sets the communication priority of the communication traffic classified as the foreground traffic by the traffic classification unit 14 and sets the communication priority of the communication traffic classified as the background traffic to decrease. .
Specifically, the priority setting unit 15 outputs information for increasing or decreasing the priority to a priority control device (not shown). The priority control device changes the communication priority or changes the band to be used based on the input priority information.
Note that the priority setting unit 15 may perform control for changing the communication priority or changing the band to be used based on the priority information.

  Further, the traffic determination unit 13 is based on the determination based on the number of contents acquired by the content number acquisition unit 131, the determination based on the number of servers acquired by the server number acquisition unit 132, and the periodicity analyzed by the periodicity analysis unit 133. The determination and the determination based on the ratio of the data amount acquired by the load amount ratio acquisition unit 134 may be comprehensively determined by weighting provided for each determination.

  FIG. 2 is a diagram illustrating an example of the communication flow storage unit 31 of the communication priority setting device 10 according to an embodiment of the present invention. As shown in FIG. 2, the communication flow storage unit 31 stores the constructed communication flow and the communication time of the communication flow (for example, the start time of the communication flow). By analyzing the communication flow stored in the communication flow storage unit 31, the number of contents in one communication flow (the number of contents acquired simultaneously by the user terminal), the number of access servers (the number of servers accessed simultaneously by the user terminal) , Information such as the periodicity of the communication flow (for example, the start time and time interval of the communication flow are regular), the ratio of the load amount (the ratio of the download data amount to the upload data amount), etc. is acquired. .

  3 and 4 are flowcharts showing processing of the communication priority setting device 10 according to an embodiment of the present invention.

  In step S103, the CPU (traffic determination unit 13) determines whether a communication flow has been established. If this determination is YES, the CPU moves the process to step S104, and if this determination is NO, the CPU ends the process.

  In step S104, the CPU (traffic determination unit 13, content number acquisition unit 131) determines whether or not the content number in the communication flow is greater than the content number threshold. If this determination is YES, the CPU moves the process to step S109, and if this determination is NO, the CPU moves the process to step S105.

  In step S105, the CPU (traffic determination unit 13, server number acquisition unit 132) determines whether or not the number of servers to be accessed in the communication flow is larger than the server number threshold value. If this determination is YES, the CPU moves the process to step S109, and if this determination is NO, the CPU moves the process to step S106.

  In step S106, the CPU (traffic determination unit 13 and periodicity analysis unit 133) determines whether or not communication in the communication flow has periodicity.

  For example, the priority of background traffic may be positively lowered. The communication traffic classified as background traffic is, for example, communication traffic that automatically updates software or periodically acquires weather information. Therefore, in communication traffic directly related to the quality of communication experienced by the user, Absent. Therefore, by reducing the priority of communication traffic classified as background traffic or actively changing the bandwidth to be used, the congestion level of communication was reduced, and as a result, it was classified as foreground traffic. As for communication traffic, it is possible to improve the quality of communication that the user actually feels.
