ملخص المقالة :
شبکه زمان‌بندی‌شده تمام نوری سوئیچینگ پاکت را در نظر بگیرید که در آن پروتکل ارتباطی اینترنت در لایه‌های بالاتر به‌کار گرفته شده است. این نوع شبکه با معضل برخورد پاکت‌ها و در نتیجه حذف پاکت‌ها مواجه است. لذا ارسال دوباره ترافیک حذف‌شده به شبکه در لایه نوری می‌تواند باعث افزایش بهره‌وری اینترنت و حتی کاهش هزینه طراحی شبکه‌های (OPS) گردد. در این روش یک کپی از ترافیک ارسال‌شده به شبکه (به‌صورت پاکت نوری) در حافظه الکترونیکی سوئیچ مرزی نگه داشته می‌شود و هر وقت که پاکت نوری ارسالی در شبکه حذف شود، پاکت نوری جدیدی از این کپی درست شده و مجدداً به شبکه ارسال می‌گردد (ارسال دوباره در لایه نوری و مستقل از لایهTCP ). به‌عبارت بهتر علاوه بر لایه (بالاتر)TCP که عمل ارسال دوباره پاکت‌های IP را انجام می‌دهد، لایه (پایین‌تر) نوری هم عمل ارسال دوباره پاکت‌های نوری را انجام می‌دهد. در این مقاله، علاوه بر ارائه روشی برای پیاده‌سازی ارزان‌تر شبکه OPS ، میزان بهره‌وری اینترنت در شبکه زمان‌بندی‌شده OPS بررسی شده و روشی برای افزایش میزان بهره‌وری اینترنت و همچنین بهبود توزیع بهره‌وری بین گره‌های دورتر از هم ارائه می‌گردد.
