About this course

من اهم المواضيع فى عالم البيانات هو توفير جودة الخدمة للأنواع المختلفة من البيانات وخصوصاً الصوت الفيديو لما يمثل اهمية لهم مقارنة ب نقل الملفات مثلاً.هذا الكورس هو فى الاصل مشروع تخرج يناقش اهمية وتأثير بروتوكولات جودة الخدمة على اداء الشبكات وخصوصاً نقل الصوت من خلال الشبكات .يبدأ الكورس بمقدمة عن تعريف واهمية جودة الخدمة حيث عرض هذا الموضوع من ماتريال كورس CCNA وايضاً كورس جودة الخدمة ممن تراك كورس CCNP-Voice حيث انه من المهم ان يتم استيعاب مفاهيم جودة الخدمة فى البدايةيستعرض الكورس بعدها الادوات المختلفة المستخدمة لتحقيق جودة الخدمة فى شبكات البيانات مثل queuing techniques, classification and marking وغيرها والتى يتم تطبيقها على اجهزة الشبكاتنتقل بعدها الى تطبيق البروتوكولات على اجهزة الروتر من خلال برنامج packet tracer من شركة سيسكو حيث نستعرض الاوامر المختلفة فى هذا الموضوع وكيفية تطبيقهاينتقل الكورس بعدها الى شرح مقدمة عن شبكات نقل الصوت وانواعها المختلفة و بروتوكولات VoIPالمختلفة مثل VoIP codec , signaling protocols SIP SDP , RTP , RTCPونشرح كيفية عمل مكالمات صوتية باستخدام بروتوكولات VoIP ثم نقوم بعمل محاكاة لشبكة بيانات وعمل configuration اللازمة لنقل الصوت عليها من خلال برنامج Opnet والذى يقوم بتحديد مصادر البيانات المختلفة ورسم الشبكة المراد محاكاتها وبعدها تحديد المعاملات المراد استخراجها من المحاكاة وبعدها تشغيل البرنامجنقوم بعدها بتشغيل بروتوكولات جودة الخدمة على سيناريو مختلف لبيان تأثيرها على اداء بيانات نقل الصوتاتمنى ان تستفيدوا من الكورس بالتوفيق دائماًد.م مصطفى الجماله
