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. |
