Hinweise

TCP ist ein Transportschichtprotokoll, das für das zuverlässige Senden und Empfangen von Datenpaketen verantwortlich ist. Sie ist in IETF RFC 793 definiert.

Ausführliche Informationen zu den für Anwendungen verfügbaren TCP-Datenverkehrsstatistiken finden Sie in der TcpStatistics Klassendokumentation. Beachten Sie, dass das von dieser Methode zurückgegebene Objekt die Statistiken zum Zeitpunkt der Erstellung des TcpStatistics Objekts widerspiegelt. Diese Informationen werden nicht dynamisch aktualisiert.
