Method for estimating, in a broadband communication system comprising an access network and a plurality of broadband communication lines associated with the access network, a sustainable speed that can be sustained by a selected broadband communication line of said plurality, the method comprising:
- for each broadband communication line of said plurality, monitoring, at monitoring time instants, an attainable speed that can be attained over the line;
- for each broadband communication line of said plurality, determining an attainable speed change that affects the broadband communication line over a monitoring time period comprising a plurality of said monitoring time instants;
- grouping the broadband communication lines of said plurality into lines groups, each lines group comprising lines associated with a same access network portion and sharing at least one line property;
- determining, for each lines group, an expected maximum attainable speed change based on a statistic of the attainable speed changes that affect the broadband communication lines of the lines group over said monitoring time period;
- and
- estimating the sustainable speed of the selected broadband communication line based on the respective attainable speeds monitored at said plurality of said monitoring time instants of said monitoring time period, and on the expected maximum attainable speed change determined for the lines group which the selected broadband communication line belongs to.
Broadband communication system comprising an access network and a plurality of broadband communication lines associated with the access network, the system further comprising:
- a module for monitoring, at monitoring time instants, an attainable speed that can be attained over each broadband communication line of said plurality;
- a module for determining, for each broadband communication line of said plurality, an attainable speed change that affects the broadband communication line over a monitoring time period comprising a plurality of monitoring time instants;
- a module for grouping the broadband communication lines of said plurality into lines groups, each lines group comprising broadband communication lines associated with a same access network portion and sharing at least one line property, and for determining, for each lines group, an expected maximum attainable speed change based on a statistic of the attainable speed changes that affect the broadband communication lines of the lines group over said monitoring time period;
- and
- a module for estimating a sustainable speed of a selected broadband communication line of said plurality based on the attainable speeds monitored at said plurality of said monitoring time instants of said monitoring time period for the selected broadband communication line, and on the expected maximum attainable speed change determined for the lines group which the selected broadband communication line belongs to.
