Title:
Performance measurement of links in packet-switched communication networks
Document Type and Number:
Japanese Patent JP6310066
Kind Code:
B2
Abstract:
A method for performing a performance measurement of a link between two nodes of a communication network. Before starting a measurement, measurement mode information including start time and packet transmission rate are provided to both nodes. At the start time, a first node generates and transmits to the other node a packet flow including packets with transmission times determined by the start time and packet transmission rate. The packet flow is divided into alternating blocks transmitted during even and odd block periods. At each block period, while the packet flow is received, a variable indicative of its behavior is updated by using the measurement mode information and detected information on reception of the packet flow. Then, a parameter indicative of a performance of the packet flow during the block period is calculated using the value reached by the variable at the end of the block period.
