| تحديد جهاز ترجمة عنوان الشبكة وجدار الحماية في أنظمة ITU(T H.323 |
تمكن التوصية ITU-T H.460.23 أي نقطة طرفية H.323 موجودة خلف جهاز FW/NAT من الإبلاغ بخصائص FW/NAT إلى حارس البوابة. وعند استعماله مع التوصية ITU-T H.460.24، يمكن لحارس البوابة استخدام معلومات FW/NAT من أجل صياغة قرار بشأن كيفية تمكين حدوث تدفق مباشر للوسائط بين جهازين. وفي معظم الأحوال، من شأن اتباع هذه الإجراءات أن يتيح لحارس البوابة تجنب الحاجة إلى وكيل وسائط كما هو موصوف في التوصية ITU-T H.460.19، حيث يمكن إرسال الوسائط بنجاح مباشرةً بين نقطتين طرفيتين تقعان خلف الأجهزة FW/NAT. |
