LINE CAPACITY ESTIMATION DEVICE, PROGRAM, AND METHOD FOR ESTIMATING FUTURE LINE CAPACITY IN CONSIDERATION OF DISTRIBUTION OF SHORT-TERM VARIATION IN TRAFFIC VOLUME

摘要

PROBLEM TO BE SOLVED: To provide a line capacity estimation device and the like for estimating a line capacity that can be accommodated at an allowable packet loss rate or less in consideration of distribution of short-term variation in traffic volume.;SOLUTION: A line capacity estimation device has: minimum line capacity calculation means calculating the minimum line capacity C_i of a buffer output side so that an allowable packet loss rate is equal to or less than an allowable packet loss rate p for each packet group i in a predetermined time period unit; stress free load factor calculation means calculating a stress free load factor ρ_i(=m_i/C_i) for each packet group i; reference value extraction means outputting one reference value combination (C₀, ρ₀) for the stress free load factor ρ₀ having the minimum value; capacity-to-load factor relation calculation means calculating a ratio allowed by an average traffic volume to an arbitrary line capacity by using a Hurst parameter Htarget; and line capacity decision means deciding the line capacity so that the average traffic volume m is equal to or less than the ratio of a stress free load factor ρ to the line capacity C.;COPYRIGHT: (C)2012,JPO&INPIT
