The growing interest in continuous media (audio/video) services, namely media streaming and multimedia conferencing over IP, coupled with technological advances in wireless and mobile networking, present new challenges and opportunities for Quality of Service (QoS) provisioning. For example, some sports events are watched by millions of online users connected to the Internet in a variety of ways including high speed connections (Cable or ADSL), modems, or wireless connections. Accommodating such large number of continuous media users, network connection heterogeneity, and the different QoS requirements for multimedia applications represents significant challenges.

人们对连续媒体(音频/视频)服务(即基于IP的媒体流和多媒体会议)的兴趣与日俱增，再加上无线和移动网络的技术进步，为服务质量(Qos)提供提出了新的挑战和机遇。例如，数百万在线用户通过各种方式连接到互联网观看某些体育赛事，这些方式包括高速连接(有线或ADSL)、调制解调器或无线连接。适应如此大量的连续媒体用户、网络连接的异构性以及对多媒体应用的不同的服务质量要求是一个巨大的挑战。
