A home network topology identification method, wherein the home network (10; 11) has a plurality of network devices (27, 28, 29) with a residential gateway (23) among them, the method comprises the following steps:
(1a) obtain at least one home network parameter from at least one of the network devices (27, 28, 29);
(1b) obtain a network channel gain function (CGF) of the home network (10; 11) from one of the network devices (27, 28, 29);
(1c) transform the channel gain function (CGF) into the time domain to obtain an equivalent estimated channel delay spread function (CDS);
(1d) obtain an estimated blind network topology from the estimated channel delay spread function (CDS) and a propagation speed of the network; and
(1e) correlate the estimated blind network topology with the at least one home network parameter to obtain at least one structural network topology parameter; and
a management center device (25) that is remote from a home network (10; 11) having a plurality of network devices (27, 28, 29) with a residential gateway (23) among them, wherein the management center device (25) is provided to carry out steps (1a) to (1e) of the method. |
