Abstract

This paper investigates the benefits of Dynamic Spectrum Management (DSM) in terms of reducing the power consumption and improving the data rates in digital-subscriber-line (DSL) networks. The proposed techniques at the three different DSM levels simultaneously also provide a significant improvement in the stability of DSLs. The proposed DSM methods are compared with other non-DSM solutions, which sacrifice power and/or data-rate in order to improve the stability, while also harming other DSLs through impolite power usage. Various examples are presented showing that the proposed DSM methods can avoid such unnecessary impoliteness, and that stability and politeness can be simultaneously achieved in a DSL network that is efficiently managed using DSM.
