چکیده

مداخل يعسوت رامعم ميمصت " ةجاحلا بسح ةددعتم طئاسو " ABSTRACT in this paper we develop a Vhdlbased scalable architecture of a multimedia on demand server model. Te three server subsystems are:the control subsystem, the communication subsystem and the storage subsystem are modeled. The communication subsystem is designed as an interconnection network with meshed-pipe structure and delivers packets to their destination through the sub-optimal shortest path. A model for the video traffic generated at the server side for modeling the data sent to the users is also presented We use simulation experiments to validate our modeling approach and compare the results with those obtained using OPNET simulation tool. The comparison results show that our approach is accurate compared to the simulation results. Our modeling approach also shows that using VHDL (Very high speed integrated circuits Hardware Description Language) in modeling digital systems is powerful and accurate. صخلم مداخل يعسوت رامعم جذومن ريوطتب انمق ثحبلا اذه يف " بسح ةددعتم طئاسو ةجاحلا " ةغل ساسا ىلع ينبم VHDL . يه و مداخلا اذهل ةيعرفلا ةمظنلاا نا : ماظن صت مت دق يعرفلا نيزختلا ماظن و ،يعرفلا لاصتلاا ماظن ،يعرفلا مكحتلا اهل جذامن ميم . و ،يكبش بوبنا بيكرت لكش ىلع ةيطبارت ةكبشك يعرفلا لاصتلاا ماظن ميمصت مت دقل رصقلاا راسملا مادختساب اهتاياغ ىلا تانايبلا مزر ليصوتب يعرفلا ماظنلا اذه موقي لثملاا . ناج يف اهديلوت متي يتلا ويديفلا رورم ةكرحل جذومن ضرع ثحبلا اذه يف اضيأ مت دقل ب نيمدختسملا ىلا ةلسرملا تانايبلا رورم ةكرح ةجذمنل مداخلا . و اهميمصتب انمق يتلا ةجذمنلا ةقيرط دييأت و ميعدتل ةاكاحم براجت مادختساب انمق دقل جمانرب مادختساب اهيلع لوصحلا مت يتلا كلتب جئاتنلا ةنراقم OPNET ةاكاحملل . نا يرط يه انتقيرط نأ نيبت ةنراقملا جئاتن ةاكاحملا جئاتنب ةنراقم ةقيقد ةق . ةقيرط نأ امك ةغل مادختسا نأ اضيأ تبثت ثحبلا اذه يف ةممصملا ةجذمنلا VHDL جذامن لمع يف ةقيقد و ةلاعف ةقيرط يه ةيمقرلا ةمظنلال .
