Title
A novel portable multimedia QoS monitor: independent and high efficiency
Abstract
In this paper, a novel multimedia QoS monitor, p3m (Portable MultiMedia Monitor), is presented. The main function of p3m is data package analysis and statistics. Breaking through the conventional method, this new QoS monitor moves jobs into kernel space, by which to meet the real-time requirements of multimedia services. With the development of broadband Internet, more and more heterogeneous multimedia services and protocols have been widely deployed. As known, there are two traditional QoS monitors. One is server-based, depending on the specific multimedia server, such as Helix. Another is tcpdump-based, e.g. mmdump, which can measure the nature of multimedia traffic merely. However, it is still difficult to monitor the QoS of multimedia networks by these two traditional strategies. To resolve the problems, our new system adopts MMPM (MultiMedia Packages Management) mechanism which can make monitor tool become server-independent and monitor the multimedia packets by preference, thus greatly reducing resource requirements with offering high performance. This paper describes the design and implementation of p3m and demonstrates one instance of its utility in monitoring the QoS of RTSP with Helix Server. The evaluation of p3m is also presented in this paper. Copyright © 2009 John Wiley & Sons, Ltd.
