The TCP/IP Protocol Family consists of,

Transport
Routing
Network Addresses
User Services
Gateway Protocols
Others

Transport

Transmission Control Protocol (TCP): connection-based services User Datagram Protocol (UDP): connectionless services

Routing

Internet Protocol (IP): handles transmission of information Internet Control Message Protocol (ICMP): handles status messages for IP Routing Information Protocol (RIP): determines routing Open Shortest Path First (OSPF): alternate protocol for determining routing

Network Addresses

Address Resolution Protocol (ARP): determines addresses Domain Name System (DNS): determines addresses from machine names Reverse Address Resolution Protocol (RARP): - determines addresses

User Services

Boot Protocol (BOOTP): starts up a network machine File Transfer Protocol (FTP): transfers files Telnet: allows remote logins

Gateway Protocols

Exterior Gateway Protocol (EGP): transfers routing information for external networks Gateway-to-Gateway Protocol (GGP): transfers routing information between gateways Interior Gateway Protocol (IGP): transfers routing information for internal networks

Others

Network File System (NFS): enables directories on one machine to be mounted on another Network Information Service (NIS): maintains user accounts across networks Remote Procedure Call (RPC): enables remote applications to communicate Simple Mail Transfer Protocol (SMTP): transfers electronic mail Simple Network Management Protocol (SNMP): sends status messages about the network
