Abstract
A video stream DSL analyzer receives at least non-physical layer management data and physical layer management data and in response generates metric information. The generated metric information is used to characterize the performance of the video stream information and diagnose any problems if necessary. In response to the metric information, the video stream DSL analyzer changes one or more DSL configuration(s) in order to improve performance.
Claims16
A method for diagnosing a video stream delivered over a digital subscriber line (DSL) network comprising:
- receiving at least non-physical layer management data and physical layer management data corresponding to the video stream;
- generating metric information in response to receiving at least the non-physical layer management data and the physical layer management data, wherein generating the metric information further comprises grouping the received non-physical layer management data and the physical layer management data for a corresponding timeslot;
- comparing the generated metric information with a performance threshold and determining whether there is a performance deficiency based on the comparison;
- determining whether there is a problem in the physical layer of the network in response to determining there is a performance deficiency;
- and
- changing at least one DSL setting in the DSL network in response to determining there is a problem in the physical layer.
A video stream DSL analyzer comprising:
- receiving means operative to receive at least non-physical layer management data and physical layer management data corresponding to the video stream;
- generating means operative to generate metric information in response to the receiving means receiving at least the non-physical layer management data and the physical layer management data, wherein the generating means is coupled to the receiving means, and further wherein the generating means is operative to generate the metric information further comprises to group the received non-physical layer management data and the physical layer management data for a corresponding timeslot;
- and
- means operative to compare the generated metric information with a performance threshold and determine whether there is a performance deficiency based on the comparison;
- means operative to determine whether there is a problem in the physical layer of the network in response to determining there is a performance deficiency
- means operative to change a DSL configuration in response to determining there is a problem in the physical layer.
A non-transitory computer readable medium containing instructions executable by one or more processors to:
- receive at least non-physical layer management data and physical layer management data corresponding to a video stream;
- generate metric information in response to at least the non-physical layer management data and the physical layer management data wherein to generate the metric information further comprises to group the received non-physical layer management data and the physical layer management data for a corresponding timeslot;
- compare the generated metric information with a performance threshold and determining whether there is a performance deficiency based on the comparison;
- determine whether there is a problem in the physical layer of the network in response to determining there is a performance deficiency;
- and
- change at least one DSL configuration in response to determining there is a problem in the physical layer.
