METHOD AND APPARATUS FOR ASSESSING THE QUALITY OF A COMMUNICATION CHANNEL IN A MULTI-DOMAIN NETWORK

摘要

A method for assessing the quality of a communication channel in a multi-domain network includes transmitting, from a device, a probe signal onto the communication channel The transmitting coordinated with the transmission of at least one alien probe signal by another network node. Subsequently to the transmitting, receiving a mixed feedback signal. The mixed feedback signal including a first component corresponding to the probe signal and a second component corresponding to the at least one alien probe signal. The method further includes extracting the first component from the mixed feedback signal, and assessing the quality of the communication channel on the basis of the extracted first component. The probe signal and the at least one alien probe signal are designed to facilitate their separation after having been superimposed.

1. A method for assessing the quality of a communication channel in a multi-domain network, the method comprising at a device attached to said communication channel :
transmitting a probe signal onto said communication channel, said transmitting being coordinated with the transmission of at least one alien probe signal by another network node; subsequently to said transmitting, receiving a mixed feedback signal, said mixed feedback signal comprising a first component corresponding to said probe signal and a second component corresponding to said at least one alien probe signal; extracting said first component from said mixed feedback signal; assessing the quality of said communication channel on the basis of said extracted first component;wherein said probe signal and said at least one alien probe signal are designed to facilitate their separation after having been superimposed.
