XNS (Xerox Network Systems) Time Protocol Resource Location Protocol (RLP)-used for determining the location of higher level services from hosts on a network Simple Mail Transfer Protocol (SMTP)-used for e-mail routing between mail servers
Telnet protocol-unencrypted text communications Secure Shell (SSH) - used for secure logins, file transfers (scp, sftp) and port forwarding Programming technique for specifying system-allocated (dynamic) ports the Domain Name System (DNS), the Routing Information Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the Simple Network Management Protocol (SNMP). UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).Īpplication examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games. UDP on port 5555 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level. UDP on port 5555 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice. UDP port 5555 would not have guaranteed communication as TCP. Guaranteed communication over TCP port 5555 is the main difference between TCP and UDP. Only when a connection is set up user's data can be sent bi-directionally over the connection.Īttention! TCP guarantees delivery of data packets on port 5555 in the same order in which they were sent. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications.
TCP is one of the main protocols in TCP/IP networks. TCP port 5555 uses the Transmission Control Protocol.
