IETF's Focus: The Internet Engineering Task Force (IETF) primarily develops and standardizes internet protocols operating at the Network Layer (Layer 3) and above in the OSI model.
Key Protocols: Some prominent IETF-developed protocols include:
IP (Internet Protocol): Foundation of internet addressing and routing.
TCP (Transmission Control Protocol): Reliable, connection-oriented data transport.
UDP (User Datagram Protocol): Connectionless, best-effort data transport.
DNS (Domain Name System): Translates domain names into IP addresses.
HTTP (Hypertext Transfer Protocol): Web communication.
