Dynamic bandwidth and symmetry allocation of digital subscriber line channels

摘要

A technique for dynamically adjusting the attributes of a DSL communications channel to satisfy varying bandwidth allocations and/or symmetry requirements. More particularly, the symmetry and/or bandwidth allocation across a communications channel, e.g. a local loop, is dynamically adjusted to satisfy particular communications transmission requirements. The dynamic adjustment of the symmetry and/or bandwidth allocation is made as a function of monitoring of the real-time usage pattern across the communications channel. Further, the dynamic adjustment of the symmetry and/or bandwidth allocation can also be made as a function of a request received from a particular application employing the communications channel. Advantageously, both symmetric and asymmetric DSL applications are satisfied across the same communications channel by dynamically adjusting the available bandwidth and/or symmetry of the communications channel.
