Congestion detection method, congestion detection apparatus, and recording medium storing congestion detection program recorded thereon

摘要

According to an aspect of the embodiments, a congestion detection method causes a computer to function as a congestion detection apparatus connectable to a network. Packets on the network are obtained and a packet loss is detected. A packet group made up of a series of packets based on the obtained packets is extracted. A packet loss in the packet group is detected and a position in the packet group where the packet loss occurred is detected. Whether congestion is occurring is judged based on the position of the packet loss in the packet group.
