Abstract
This article describes an approach to improve IP packet marking entering a Diffsery domain through dynamic policy provisioning and network feedback signaling. Traffic entering the network is dynamically tagged based on network congestion information reported by real-time resource monitoring and feedback alerts. This allows dynamic reallocation and management of resources based on current network state and applications QoS requirements.
We present an algorithm dealing with video traffic and we enhance our architecture by using meta-policies which are stored locally in the edge router of the Diffsery network. Therefore, video traffic can be marked with different PHB when entering the network. An evaluation of dynamic policy provisioning using a Java COPS and a Linux based network is also presented and evaluated over an experimental testbed.
