The current rise in community-based content sharing and growing popularity of personalised multimedia transmission is accompanied by user-side quality demands. Internet, on the other hand, still provides merely best-effort service and thus only implicit feedback on critical network conditions through packet loss and delays. In order to satisfy future quality demands, feedback on quality problems needs to become much more explicit than what is the case today. In order to highlight the potential for improvement, this paper first identifies and analyses today’s feedback flows between users, applications, networks and the corresponding service providers. Based on this inventory, a new kind of feedback system employing self-organising overlay technology is introduced and exemplified. This future-proof system, developed within the European series of Networks of Excellence EuroNGI, EuroFGI and EuroNF, provides added feedback value to the above-mentioned stakeholders and furthermore a smooth transition path from current legacy towards future service management solutions.
Pappret identifierar problem med nuvarande mest implicita kvalitetsåterkoppling mellan nätverksoperatörer, tjänsteleverantörer och användare. Det introducerar ett koncept för mer explicit och framtidsinriktad kvalitetsåterkoppling som bygger bl a på självorganierande overlay nätverk.
