Active Service Quality Management in ASEMA system

Abstract

One of the purposes of the Active Service Environment Management system (ASEMA) is to provide the best possible multimedia service experience to end users. This is realized by dynamically adapting to changes in service environment's configuration and used network infrastructure's quality of service (QoS) changes. The research problem of the paper is to find a solution for proactive approach to manage multimedia service performance in a dynamic service environment. The research is based on the constructive method by analyzing the related publications and experimentation with the selected technologies by implementing the solutions part of the ASEMA prototype. The prototype has profile negotiation functionality that dynamically updates ASEMA profiles according to dynamic changes in an end user's service environment. The quality of service management functionality in ASEMA monitor's actively underlying network's QoS level. It adjusts quality of video stream according to the changes in QoS levels of the used network infrastructure.

Quality-of-Service Management in ASEMA System for Unicast MPEG4 Video Transmissions

“…The media player in client device connects to the video streaming bypass server, which in turn opens a socket connection to the device that transmits video stream to the ASEMA system, which in this case is the web camera. [9] …”

“…The GNM server keeps tract on the endusers roaming client devices to the ASEMA system all the time. [9] …”

“…The quality and the quantity of the transmission content can be readjusted during transmission. [9] The intent of the video streaming bypass server is to offer interface for monitoring video stream. It collects video stream throughput data for scalable QoS calculations.…”

“…Finally there is a web camera with capability to stream video and to be controlled remotely by an end-user. [9] …”

“…It may inform end-user of new components that must be installed prior to particular service that is requested can be executed at the end-user' s service environment. [9] 4.1. ASEMA system architecture The prototype ASEMA system architecture is depicted below in figure 1.…”
