Selected sections of this report were presented at the Third European Research Seminar on Advances in Distributed Systems (ERSADS'99), Madeira Island, Portugal, 23-28 April 1999.
The paper gives examples of applications where the stacks supporting different QoSs are not independent. We show that these dependencies are hard to express with current communication architectures and propose a novel approach that supports a style of micro-protocol composition that satisfies both inter-QoS and intra-QoS constraints.
