Dynamic line management

摘要

A management device for use in an access network including a plurality of data connections between end user devices and an aggregation transceiver device where the connections are aggregated for onward connection through the access network, the access network storing in association with each data connection a Dynamic Line Management, DLM, profile which specifies a set of values for a plurality of parameters associated with the respective data connection, together with a stability level specifying a desired level of stability for the data connection. The device includes means for receiving monitoring data specifying the stability of each respective data connection over a predetermined period of time; means for selecting a DLM profile to be applied to the connection in dependence on both the monitoring data and the stored stability level associated with the data connection; and means for requesting an OSS system of the access network to apply the selected profile to the data connection. The DLM profile selection means disregards any resynchronizations or errors estimated to have occurred as a result of an area wide event such as a thunderstorm. It performs this estimation by detecting a large number of retrains and or errors occurring within a predetermined short test period.

1. A method of operating an access network including a plurality of data connections between end user devices and an aggregation transceiver device where the connections are aggregated for onward connection through the access network, the method comprising:
storing a plurality of different profiles, each of which specifies a set of values for a set of one or more parameters associated with each data connection, and, for each data connection, monitoring performance of the connection; selecting one of the stored profiles to be applied to the connection in dependence on a result of monitoring the connection; and applying the selected profile to the data connection, wherein monitoring the connection includes determining a number of mal-performance events occurring, within a given period of time, and estimating a number of those mal-performance events occurring as a result of an area-wide event affecting a plurality of lines and disregarding any such mal-performance events when selecting a profile to apply to the data connection, and wherein estimating the number of mal-performance events occurring as a result of an area wide event includes determining a proportion of live connections within a predetermined group of connections suffering a resynchronization within a test period of a predetermined duration and comparing the proportion with a threshold and identifying all such resynchronization as being caused by an area wide event if the proportion exceeds the threshold.
