Summary
" Quality of service in local area networks is becoming more and more important,since bandwidth intensive applications are increasing in modern households, butthe infrastructure is often limited. State of the art research and standardisationknows of QoS technologies targeting QoS in consumer networks, but theseoften require deployment on all devices, are limited to certain access technologyor lack autonomous configuration support. This thesis presents a novelapproach to Quality of Service in unmanaged Local Area Networks, called theQoSiLAN framework. It does not rely on network infrastructure support, buton host cooperation. It identifies traffic with a QoS demand and predicts therequired resources to enable per-link bandwidth reservations in an autonomousmanner. In contrast to traditional approaches, the bandwidth reservation is notrealised explicitly by infrastructure support, but implicitly by host cooperation.This works by involving cooperating hosts, which limit their bandwidth outputto not over-provision links with active QoS reservations in the network, whilea full device coverage is not required essentially. The resource managementand admission control is coordinated by a dedicated QoSiLAN Manager host,which also maintains a detailed link layer network topology map to make sophisticatedresource policing admissions on link basis. To enable the QoSiLANframework, this Thesis contributes the framework as well as new knowledge tothe enabler technologies for traffic identification, resource prediction, topologymapping, policing and admission control as well as a dedicated QoS signallingcommunication protocol."--Page 24.
