Über TCP/UDP Ports

Der TCP Port 21 verwendet das Transmissionskontrollprotokoll. TCP ist eins der Hauptprotokolle in TCP/IP Netzwerken. TCP ist ein auf die Verbindung orientiertes Protokoll, das einen Händedruck braucht, um Ende-bis-Ende Kommunikationen einzustellen. Die Daten eines Benutzers können bidirektional über die Verbindung nur nach der Einstellung der Verbindung gesandt werden.
Achtung! TCP port 21 garantiert die Lieferung der Datenpackungen in derselben Ordnung, darin sie gesandt wurden. Garantierte Kommunikation über den TCP Port 21 ist der Hauptunterschied zwischen TCP und UDP. Der UDP hat keine garantierte Kommunikation wie TCP.

UDP port 21 besorgt einen unzuverlässigen Dienst und Datagramme können ohne Meldung verdoppelt, unzulässig kommen oder verschwinden. UDP port 21 denkt, dass die Fehlernachprüfung und -korrektion nicht erforderlich ist oder in dieser Anwendung nicht vollgezogen wird, um das Overhead dieser Bearbeitung auf dem Netzwerkschnittstellniveau zu vermeiden.
UDP (Benutzerdatagrammprotokoll) ist ein minimales Transportschichtprotokoll, das auf Meldungen orientiert ist (das Protokoll ist in IETF RFC 768 orientiert). Anwendungsmuster, die UDP oft verwenden: Überstimme IP (VoIP), Strommedia und Echtzeitspiele mit vielen Spielern. Viele Webanwendungen verwenden UDP, z. B., Domänennamensystem (DNS), Routerinformationsprotokoll (RIP), dynamisches Hostcomputerkonfigurationsprotokoll (DHCP), einfaches Netzwerkmanagementprotokoll (SNMP).
TCP versus UDP - TCP: zuverlässig, ordentlich, schwer, strömend; UDP – unzuverlässig, unordentlich, leicht, Datagramme.
