Definitions

  • the present invention relates to an analysis device, an analysis method, and a storage medium.
  • Patent Document 1 discloses an RTT calculation unit as a means for calculating the RTT of a signal transmitted and received between a client device and a server device by extracting a plurality of signals as samples, and an RTT calculation unit calculated by the RTT calculation unit.
  • a technique is disclosed for an apparatus that includes a dispersion determination as means for determining dispersion, and a sample number adjustment section as means for adjusting the number of samples based on the determination result of the dispersion determination section.
  • the analysis device determines whether communication packets in the communication network are different based on the difference in arrival time of communication packets between the first communication device and the second communication device connected via the communication network.
  • Feature information specifying means for specifying feature information regarding the arrival time of each of the different communication routes.
  • FIG. 1 is a diagram showing a communication device including an analysis device according to the present embodiment and a communication network to which the communication device is connected.
  • FIG. 3 is a first diagram illustrating response times according to time between communication devices according to the present embodiment.
  • FIG. 7 is a second diagram showing response times according to time between communication devices according to the present embodiment.
  • FIG. 3 is a diagram illustrating a delay regarding a response in a communication device of a communication destination according to the present embodiment.
  • FIG. 3 is a diagram illustrating an example of communication characteristic information on a certain communication route according to the present embodiment.
  • FIG. 7 is a diagram illustrating an example of communication characteristic information for each of a plurality of communication paths according to the present embodiment.
  • FIG. 2 is a functional block diagram of the analysis device according to the first embodiment.
  • FIG. 1 is a diagram showing a communication device including an analysis device according to the present embodiment and a communication network to which the communication device is connected.
  • FIG. 3 is a first diagram illustrating response times according to
  • FIG. 9 is a diagram showing measurement results and characteristic information regarding response time according to the first embodiment.
  • the response time RTT of the measurement results is mostly distributed between around 10.2 milliseconds and around 12.6 milliseconds. Note that the distribution of response times RTT in the measurement results may exceed the range shown in FIG. Information on the range of responses may be used.
  • the analysis unit 13 acquires such measurement results from the measurement result storage unit 101.
  • the analysis unit 13 calculates first characteristic information regarding the response time based on the measurement results (FIG. 9(A)) (step S104).
  • the first feature information is shown in FIG. 9(B) and FIG. 9(C).
  • the analysis device 10 can notify of an abnormality or the like based on the status of the change in the communication path. This allows the user to understand abnormalities caused by changes in the communication paths that constitute the communication network between communication devices.
  • the non-volatile recording medium 84 is a computer readable disk, such as a compact disk (Compact_Disc) or a digital versatile disk (Digital_Versatile_Disc). Furthermore, the nonvolatile recording medium 84 may be a universal serial bus memory (USB memory), a solid state drive (Solid_State_Drive), or the like. The non-volatile recording medium 84 retains such programs even without supplying power and allows portability. The nonvolatile recording medium 84 is not limited to the above-mentioned media. Further, instead of the nonvolatile recording medium 84, the program may be carried around via the communication IF 87 and communication network. Volatile storage 82 is computer readable and can temporarily store data. The volatile storage device 82 is a memory such as DRAM (dynamic random access memory) or SRAM (static random access memory).
  • DRAM dynamic random access memory
  • SRAM static random access memory
  • the CPU 81 copies a software program (computer program: hereinafter simply referred to as a "program") stored on the disk 83 to the volatile storage device 82 when executing it, and executes arithmetic processing.
  • the CPU 81 reads data necessary for program execution from the volatile storage device 82. If display is required, the CPU 81 displays the output result on the output device 86.
  • the CPU 81 reads the program from the input device 85.
  • the CPU 81 interprets and executes the analysis program (FIG. 4 or 5) stored in the volatile storage device 82 that corresponds to the functions (processing) represented by each part shown in FIG. 2 (or FIG. 3).
