ملخص المقالة :
این مقاله به معرفی روشی برای بستهبندی صدا جهت انتقال روی شبکه اینترنت میپردازد. هدف از این روش آن است که تا حد ممکن از کاهش کیفیت صدا بهدلیل گمشدن بستههای صوتی در شبکه جلوگیری شود. این روش اجازه بازسازی بستههای گمشده را در حین عبور از شبکه در گرههای فعال شبکه میدهد، لذا کیفیت صدای دریافتی در گیرنده بالاتر از روشهای عادی انتقال صدا روی اینترنت خواهد بود. کارآیی این روش بهوسیله شبیهسازی یک شبکه انتقال داده کاملاً غیر امن بههمراه یک گره فعال بررسی شده و نشان داده شده که کیفیت صدای دریافتی حتی با 50% بستههای گمشده نیز بسیار بهتر از روشهای دیگر انتقال صدا میباشد.
