In computer networking, a reliable protocol is a communication protocol that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for assurance, which is the term used by the ITU and ATM Forum. Reliable protocols typically incur more overhead than unreliable protocols, and as a result, function more slowly and with less scalability. This often is not an issue for unicast protocols, but it may become a problem for reliable multicast protocols.

  • In Bezug auf Telekommunikation bedeutet Zuverlässigkeit, dass Nachrichten mit einer angestrebten Quality of Service (QoS) übermittelt werden. Beispiele für QoS für die Nachrichtenübertragung sind: 1. * alle gesendeten Daten kommen vollständig an 2. * die Daten kommen in der richtigen Reihenfolge an 3. * es gibt keine Duplikate Um dies zu realisieren, werden u. a. Sequenznummern zusammen mit Quittungen (Empfangsbestätigungen) und Sendewiederholungen verwendet. Ein Beispiel für ein zuverlässiges Protokoll ist TCP; ein Beispiel für ein nicht zuverlässiges Protokoll ist UDP. (de)
  • Con network reliability, in italiano affidabilità di rete, si definisce la stabilità di una rete, sia essa logica o fisica. (it)
  • 在计算机网络中,可靠的协议是一种通信协议。这种协议由接受方通知发送方数据是否成功接收。可靠性是保证的代名词,是国际电联和ATM论坛使用的术语。 可靠的协议通常会比不可靠的协议产生更多的开销,因此,运行速度较慢且可伸缩性较低。对于单播协议,这通常不是问题,但对于可靠的多播协议,则可能成为问题。 传输控制协议(TCP)是Internet上使用的主要协议,是一种可靠的单播协议。 UDP是一种不可靠的协议,通常用于计算机游戏,流媒体或其他由于速度问题而可能会容忍某些数据丢失的场景。 通常,可靠的单播协议也是面向连接的。例如,TCP是面向连接的,虚电路ID由源IP地址和目标IP地址以及端口号组成。但是,某些不可靠的协议是面向连接的,例如异步传输模式和帧中继。此外,某些无连接协议(例如IEEE 802.11)是可靠的。 (zh)
  • Spolehlivý protokol v počítačových sítích poskytuje určité vlastnosti týkající se spolehlivosti doručení dat určenému příjemci nebo příjemcům. Za nespolehlivé se naopak považují protokoly, které neinformují odesilatele dat, zda byla úspěšně doručena. Termín „spolehlivý“ (anglicky reliable) je synonymem pro „zaručený“ (anglicky assured), které používá Mezinárodní telekomunikační unie (ITU) a v kontextu ATM koordinační funkce specifické pro jednotlivé služby (anglicky ATM Service-Specific Coordination Function), například pro transparentní zaručené doručení u .

  • Dans les réseaux informatiques, un protocole fiable fournit l'assurance de la livraison des données au destinataire(s), par opposition à un protocole peu fiable, qui ne fournit pas de notifications à l'expéditeur concernant la livraison des données transmises. La fiabilité est un synonyme de l' assurance, qui est le terme utilisé par l'UIT et le forum de l'ATM dans le cadre de sa fonction de coordination spécifique au service ATM, par exemple pour assurer la transparence de la livraison assurée avec AAL5.
