Providing Quality of Service in a multimedia context in next generation Internet poses a number of open challenges, especially regarding routing and resource management strategies. In fact, the massive amount of data that is envisaged to be transported in the near future (especially in a Differentiated Services framework) will make it difficult to have networks that are deeply rearrangeable in real time. A more realistic framework will most likely see a joint action of low-level, fastly reactive, and high-level, slowly reactive, tuning operations. Within this trend, we introduce and analyze a system in which bandwidth assignment and routing are readjusted within a layered architecture. Low-level local tuning procedures are fastly reactive and operate on small parts of the network; high-level control actions act on a much longer time scale and affect the whole network: they are able to perform global reallocations in order to cope with heavy network traffic variations. It is shown by numerical simulation results that the use of the proposed mechanism positively affects the overall network performance.
