Patent ID: 8675495

Claim:
A communication system including a transmission device configured to transmit a packet and a reception device configured to receive the packet, wherein: the reception device includes: a behavior information acquisition unit configured to acquire behavior information that represents behavior of the received packet from when the packet is transmitted by the transmission device to when the packet reaches the reception device; a model specification information acquisition unit configured to acquire model specification information for specifying a mathematical model representing the behavior of a plurality of packets based on the behavior information acquired for each of the plurality of packets, wherein said mathematical model is a model represented by a probability density function f(x) formed by the linear sum of a plurality of probability density functions using behavior information as a random variable x; and a model specification information transmission unit configured to transmit the acquired model specification information to the transmission device; and the transmission device includes a model specification information reception unit configured to receive the model specification information transmitted by the reception device.
