ONE-WAY DELAY MEASUREMENT IN A PACKET-SWITCHED COMMUNICATION NETWORK

ONE-WAY DELAY MEASUREMENT IN A PACKET-SWITCHED COMMUNICATION NETWORK

A method for performing a one-way delay measurement on a bidirectional packet flow carrying live traffic exchanged between two nodes of a packet-switched communication network. At predefined times, each node transmits to the other node a respective marked packet of the bidirectional packet flow. Eac...

description A method for performing a one-way delay measurement on a bidirectional packet flow carrying live traffic exchanged between two nodes of a packet-switched communication network. At predefined times, each node transmits to the other node a respective marked packet of the bidirectional packet flow. Each node then transmits unmarked packets of the bidirectional packet flow, until it receives the marked packet transmitted by the other node. In response thereto, each node transmits to the other node another marked packet of the bidirectional packet flow. A measurement point may be placed on the path of the bidirectional packet flow, for detecting the marked packets transmitted in either direction, and for providing a one-way delay measurement based on their detection times.
