Information-processing device, information-processing method, and information-processing program product
First Claim
1. An information-processing device for communicating with a communication device, comprising:
- a RTT measurement unit configured to measure a round trip time (RTT) between the information-processing device and the communication device;
a RTT judgment unit configured to determine whether the round trip time measured by the RTT measurement unit exceeds a predetermined upper limit value, and put a restriction on the communication with the communication device if the round trip time exceeds the predetermined upper limit value;
a unit-type information acquiring unit configured to acquire an identification of the communication device when the round trip time is not greater than the predetermined upper limit value;
a limit value judgment unit configured to measure an amount of cumulative information accumulated in proportion to a communication amount when content is transmitted to the communication device, wherein when the measured amount of cumulative information exceeds a given limit value, the RTT measurement unit measures the round trip time, the RTT judgment unit performs the determination of whether the round trip time exceeds the predetermined upper limit value, and the measured amount of cumulative information is reset if the round trip time does not exceed the predetermined upper limit value;
a cumulative information storage unit configured to store the measured amount of cumulative information in a nonvolatile memory; and
a cumulative information management unit configured to control to store the cumulative information in the cumulative information storage unit at a write frequency which is lower than the frequency at which the limit value judgment unit measures the amount of cumulative information.

9. A computer-readable storage medium having encoded thereon computer executable program instructions for communicating with a communication device, the computer executable program instructions that, when executed by a computer, cause the computer to perform:
-
measuring a round trip time between the information-processing device and the communication device; determining whether the round trip time exceeds a predetermined upper limit value, and putting a restriction on the communication with the communication device if the round trip time exceeds the predetermined upper limit value; acquiring an identification of the communication device when the round trip time is not greater than the predetermined upper limit value; measuring an amount of cumulative information accumulated in proportion to a communication amount when content is transmitted to the communication device, wherein when the measured amount of cumulative information exceeds a given limit value, the round trip time is measured, it is determined whether the round trip time exceeds the predetermined upper limit value, and the measured amount of cumulative information is reset if the round trip time does not exceed the predetermined upper limit value; and storing the measured amount of cumulative information in a nonvolatile memory at a write frequency which is lower than the frequency at which the amount of cumulative information is measured. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An information-processing method for communicating with a communication device, comprising:
-
measuring a round trip time between the information-processing device and the communication device; determining whether the round trip time exceeds a predetermined upper limit value, and putting a restriction on the communication with the communication device if the round trip time exceeds the predetermined upper limit value; acquiring an identification of the communication device when the round trip time is not greater than the predetermined upper limit value; measuring an amount of cumulative information accumulated in proportion to a communication amount content is transmitted to the communication device, wherein when the measured amount of cumulative information exceeds a given limit value, the round trip time is measured, it is determined whether the round trip time exceeds the predetermined upper limit value, and the measured amount of cumulative information is reset if the round trip time does not exceed the predetermined upper limit value; and storing the measured amount of cumulative information in a nonvolatile memory at a write frequency which is lower than the frequency at which the amount of cumulative information is measured.
