Data communication

摘要

A management device is used 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 stores a plurality of different profiles, each of which specifies a set of values for a plurality of parameters associated with each data connection. The device applies one of the stored profiles to each connection, and receives a notification in the event of one of a predetermined set of notifiable events occurring on the connection. It is determined if more than a predetermined number of notifications are received within a predetermined period for a respective connection and, in the event of such a determination being made, a different one of the profiles is caused to be applied to the connection.

1. A method of controlling a data connection including first and second modems with a transmission line there between, the method comprising:
executing a first and a second monitoring process for monitoring stability of the data connection over a first and a second time scale respectively, wherein the first monitoring process comprises periodically assessing performance of the data connection based on performance metrics pertaining to the performance of the data connection since the preceding periodic assessment of the first monitoring process, with the period between consecutive periodic assessments corresponding to the first time scale, and, in the event that it is assessed that a modification to operational parameters of the data connection is appropriate, modifying the operational parameters of the data connection in dependence upon the assessment, wherein the second monitoring process comprises detecting the occurrence of one or more events or series of events indicative of the data connection behaving unstably within a second period of time from completion of the occurrence and, in response to such detection, modifying the operational parameters of the data connection, wherein the second monitoring process is completed within a period of time corresponding to the second time scale which is within the period between consecutive periodic assessments of the first monitoring process and is completed without awaiting the next periodic assessment of the first monitoring process after completion of the occurrence of one or more events or series of events indicative of the data connection behaving unstably, and wherein the first and second modems are digital subscriber line modems.
