Ztráta paketů (anglicky packet loss) je v informatice chyba při přenosu dat v počítačové síti. Nastává, když jeden nebo více paketů putujících přes počítačovou síť nedosáhne svého cíle. Ztráta paketů je brána jako jeden ze tří hlavních problémů v digitální komunikaci. Zbylé dva problémy jsou bitová chyba a falešné pakety způsobené rušením. (cs) Paketverlust (engl. packet loss) tritt bei der paketbasierten Datenübertragung in Rechnernetzen und Kommunikationsnetzen auf. Es gibt verschiedene Ursachen für Paketverlust: * Fehler des Übertragungsmediums * Paketverlust bei der Verarbeitung/(Zwischen-)Speicherung der Pakete * Paketverlust aufgrund des Nichteinhaltens von Regeln und Standards Paketverlust kann in verschiedenen Schichten des OSI-Modells auftreten. (de) La perte de paquets se produit lorsqu'un ou plusieurs paquets de données transitant par un réseau informatique n'arrivent pas à destination. La perte de paquets est causée soit par des erreurs de transmission de données, généralement sur des réseaux sans fil soit par une congestion du réseau. La perte de paquets est mesurée en pourcentage des paquets perdus par rapport aux paquets envoyés. Le protocole de transmission de données informatiques (TCP en anglais) détecte la perte de paquets et effectue des retransmissions pour assurer une messagerie fiable . La perte de paquets dans une connexion TCP est également utilisée pour éviter la congestion et produit ainsi un débit intentionnellement réduit pour la connexion. Dans les médias en streaming et les applications de jeux en ligne, la perte de paquets peut affecter la qualité d'expérience (QoE) d'un utilisateur. (fr) Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion. Packet loss is measured as a percentage of packets lost with respect to packets sent. The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging. Packet loss in a TCP connection is also used to avoid congestion and thus produces an intentionally reduced throughput for the connection. In real-time applications like streaming media or online games, packet loss can affect a user's quality of experience (QoE). (en) Packet loss (perda de pacote) ocorre quando um ou mais pacotes que navegam sobre uma rede de computadores falha em alcançar o destinatário, sendo um dos erros previstos na transmissão de dados. (pt) 丟包（Packet loss）是指一個或多個数据包（packet）的資料無法透過網路到達目的地。丟包與位元錯誤（bit error）與噪聲（noise）所造成的虛假的封包（spurious packets）是三個最主要的數字通信錯誤的原因。 (zh) |
