تعتمد شبكات الند للند على التعاون بين المستخدمين والتشارك في الموارد، و قد شاع استخدام هذا النوع من الشبكات في كثير من التطبيقات، من أشهرها مشاركة الملفات. تقسم تطبيقات مشاركة الملفات، المعتمدة على بنية الند للند إلى منظومات مركزية (تعتمد على وجود مخدم مركزي لتنظيم العمل) و منظومات موزعة، كما يمكن أن تقسم إلى منظومات بنيوية أو غير بنيوية، تبعاً لآلية إدارة المعلومات و تنظيمها ضمن المنظومة.
يقدم هذا المقال تطبيق ند لند مركزياً يستخدم من أجل مشاركة الملفات فضلاً عن نتائج الاختبارات على هذا التطبيق، التي تؤكد ميزات شبكات الند للند من حيث التصعيد الكبير و وثوقية التطبيق.
The advantage of peer-to-peer (P2P) paradigm relies on two main concepts: cooperation among
users and resource sharing. There are many applications based on peer-to-peer paradigm, but
the most popular one is the file sharing. We can classify the file sharing application into
centralized systems, (having a central server), and decentralized systems. Another classification
would be structured and unstructured systems, based on the way of managing the indexing
information. In this paper, we have implemented a centralized peer-to-peer application for file
sharing. Then we evaluated the performance of the system by means of simulation.
