Patent ID: 8824453

Claim:
A network management system, comprising: a memory storing computer instructions; and a controller coupled with the memory, wherein the controller manages operations of a digital subscriber line access multiplexer interfacing to a digital subscriber line modem over a digital subscriber line, wherein the controller, responsive to executing the computer instructions, performs operations comprising: detecting a signal quality violation in the digital subscriber line according to a quality policy associated with a content type, wherein the digital subscriber line transmits a plurality of content types, and wherein each of the plurality of content types has an associated quality policy; determining a transmission delay associated with interleaving of all content transmitted by the digital subscriber line access multiplexer; determining whether the transmission delay exceeds a predetermined delay threshold associated with the content type; responsive to determining that the transmission delay does not exceed the delay threshold, causing the digital subscriber line access multiplexer to interleave all content supplied to the digital subscriber line; responsive to determining that the transmission delay exceeds the delay threshold, causing the digital subscriber line access multiplexer to allocate to a first content source a first portion of a data service bandwidth assigned to the digital subscriber line for providing first content via the digital subscriber line with a transmission delay not exceeding the delay threshold associated with the content type of the first content and in accordance with the quality policy associated with the content type of the first content, wherein a remaining portion of the data service bandwidth is allocated for remaining traffic, and wherein the remaining traffic is not permitted to utilize the first portion of the data service bandwidth.
