The proceedings contain 34 papers. The special focus in this conference is on Wireless Multimedia Systems, Communication Protocols for Multimedia, Scheduling Issues and Quality of Service Architectures. The topics include: The impact of wireless device access on content delivery networks;adaptive access regulation for VBR video streams;packetization scheme for streaming high-quality audio over wireless links;preserving established communications in ipv6 multi-homed sites with MEX;observations on equation-based estimation of TCP-compatible rate for multi-rate multicast scenarios;smoothing the TCP rate by learning the delay versus window size dependency;KOM scengen the Swiss army knife for simulation and emulation experiments;the effect of per-input shapers on the delay bound in networks with aggregate scheduling;scheduling and quality differentiation in differentiated services;size-distortion optimized proxy caching for robust transmission of mpeg-4 video;design and performance evaluation of a price-based cache algorithm for mobile web services;admission control and resource reservation framework for the OMODIS QOS framework;performance evaluation of the preemptive bandwidth allocation protocol;impact of network topology on the performance of budget based network admission control methods;breaking the network transparency paradigm;quality differentiation with source shaping and forward error correction;enhancing the coexistence of unicast and multicast sessions in diffserv architecture;session sharing as middleware service for distributed multimedia applications and spatio-temporal QOS pattern analysis in large scale internet environment.

In this paper we discuss a new parallel algorithm of 2-D Discrete Wavelet Transform（DWT） using MPIcatterv and MPIatherv（MPI:Message Passing Interface）.In this algorithm,the 2-D sequential Daubechies Discrete Wavelet Transform program is first decomposed into several 1-D transforms,and then the parallel conversion is made on *** parallel program has already been successfully implemented on the Dawning parallel Computer System,and experimental results show that high performance and pretty flexibility can be achieved.
