Explains the connection, delivery, and application characteristics of TCP, UDP, and RAW transports and identifies when their default settings are sufficient.
TCP, UDP, and RAW transports are Internet Protocol (IP) transport options that
-
provide connection-oriented or connectionless data exchange
-
carry traffic for multiple applications and protocols, and
-
use default settings that meet the requirements of most sites.
Transmission Control Protocol (TCP) is a connection-oriented protocol that defines the data and acknowledgment formats that two systems exchange. It also defines procedures that help the systems deliver data correctly.
TCP allows multiple applications on one system to communicate concurrently by demultiplexing incoming traffic among the applications.
User Datagram Protocol (UDP) is a connectionless transport-layer protocol in the IP family. Application-layer protocols that use UDP include Network File System (NFS), Simple Network Management Protocol (SNMP), Domain Name System (DNS), and TFTP.
A RAW transport carries an IP protocol other than TCP or UDP.
