Introduction The integration of distributedmultimedia# systems support into a communications architecture encompassing the new multiservice networksposes# significant challenges. A key observation about the new environment is that Quality of Service (QOS) provides a unifying theme around which most of thenew# communications requirements [Leopold,92] can be grouped.# For applications relying on the transferof# multimedia information, and in particular continuous media, it is essential that QOS is guaranteed system-wide, including the distributed system platform, the transport protocol and the multiservice network. Enhanced protocol support such as end-to-end QOS negotiation, renegotiation, indication of QOS degradations and co-ordination over multiple related connections are also required.
