Abstract:
1. A method comprising: communicating, by a customer premise equipment (CPE) with Digital Subscriber Line Access Multiplexer (DSLAM) via a digital subscriber line (DSL) associated with an available bandwidth, the digital subscriber line being a single line where allocation of the available bandwidth is reversible between a normal mode, wherein a downstream speed exceeds an upstream speed over said digital subscriber line, and a reverse mode wherein said upstream speed exceeds said downstream speed over said digital subscriber line; identifying a triggering event indicating a demand for additional upstream speed based on an analysis of the current traffic pattern; responsive to identifying the triggering event, sending a speed reversal message configured to initiate a switch from normal mode of communication over the digital subscriber line to reverse mode of communication over the digital subscriber line; and switching to reverse mode responsive to said speed reversal message wherein switching increases said upstream speed and decreases said downstream speed to re-allocate said available bandwidth oppositely in said digital subscriber line without increasing said available bandwidth.
