جدول التدفق

يتتبع Argo كل اتصال. وطريقة استعلامك عن الجدول أهم من محتوياته، لأن التفريغ الكامل غير محدود من حيث المبدأ وغير عملي من حيث التطبيق.

flow-l-match

Section titled “flow-l-match”

هذا هو الأمر الذي تحتاجه في معظم الحالات. يأخذ عنوانًا، أو عنوانًا ومنفذًا.

الإجراء المرتبط بكل تدفق هو بيت القصيد: F تمرير، D إسقاط، N ترجمة عناوين (NAT). وجود تدفق بالإجراء D يعني أن مستوى البيانات اتخذ قرارًا متعمدًا، وهو ما يوجّهك إلى السياسة بدلًا من الاتصال.
