Minimal Delay Violation-Based Cross-Layer Scheduler and Resource Allocation for DSL Networks

The quality of service many modern communication systems depends on the delay performance underlying network. In digital subscriber line (DSL) networks, for example, crosstalk introduces competition data rate among users, which influences distribution. such a competitive environment, is largely determined by manner in resources are dynamically allocated to different users. A common approach this allocation problem through cross-layer scheduler. Such scheduler violates OSI model allowing between layers, order steer physical layer towards operating points that maximize some upper metric. paper, we present new and resource algorithm context DSL referred as minimal violation (MDV) scheduler, aims minimize number violations achieve high throughput. Rather than solving linear network utility maximization problem, most other schedulers from literature, consider reciprocal with rate, allocate rates at finer level, while still maintaining good performance. Through simulations, show MDV performs better scheduling algorithms literature respect packet loss ratio, throughput various scenarios, often operates closely an ideal
