Abstract

"Next generation Internet comes with the responsibility to offer good support to maintain Quality of Service (QoS) to users that want to pay more to have better services. New management mechanisms are created to issue the sensibly augmented complexity of differentiated services. Multimedia applications are one of the main goals of this new infrastructure. This paper proposes a more flexible way to install and apply management mechanisms. This flexibility comes from a programmable management plane as structural component of protocol stack. With the capability to self-configure management actions, according to traffic situations, and with the possibility to build and install new mechanisms to help new services, an active and programmable network management can offer customized support to user applications. As a case study, we show a scheme where core nodes in a network deal with various management mechanisms, such as selective discard, feedback to source and priority queuing to achieve multimedia jitter-sensible transport."
