US 2008/0259809 A1 · Performance Measurement in a Packet Transmission Network

Abstract

A data packet transmission network comprises a stream of packets of data sent by a first terminal passes in transit through at least one network equipment with which there is associated a stream measurement unit; wherein said first terminal and said measurement unit are connected to a collection unit. The measurement method comprising the following steps: the first terminal sends a specific stream of packets, each having a different determined size, the sizes being such that in a set of r packets, r being a positive integer less than or equal to the number of packets of the stream, there are not two subsets comprising the same number of packets and having the same cumulative total size; the measurement unit analyzes at least one packet and at most r packets of said stream passing in transit through the network equipment.

Dependent claims

A measurement method for use in a data packet transmission network, wherein a stream of packets of data sent by a first terminal passes in transit through at least one network equipment with which there is associated a stream measurement unit;

wherein said first terminal and said measurement unit are connected to a collection unit;
said method comprising the following steps:
the first terminal sending a specific stream of packets, each having a different determined size, the sizes being such that in a set of r packets, r being a positive integer less than or equal to the number of packets of the stream, there are not two subsets comprising the same number of packets and having the same cumulative total size;
the measurement unit analyzing at least one packet and at most r packets of said stream passing in transit through the network equipment;
the first terminal sending the collection unit a sent packet stream description, comprising a list including at least said determined sizes of the sent packets;
the stream measurement unit sending the collection unit a stream description comprising at least the number of analyzed packets and a sum of said determined sizes of the analyzed packets;
and
the collection unit identifying each analyzed packet of the stream as a function of the stream description and of said determined sizes of the sent packets in order to correlate said stream description and said sent packet stream description packet by packet.
