Question

name 5 network protocol with their applications, find their RFC with searching on internet ( if there are multiple RFC for one protocol, write the oldest one).

Answer 1

Following are 5 network protocols with their applications and RFCs.

1.

ARP

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network.

RFC 826

An Ethernet Address Resolution Protocol or Converting Network Protocol Addresses

2.

ICMP

ICMP (Internet Control Message Protocol) is an error-reporting protocol network devices like routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets.

RFC 777

Internet Control Message Protocol

3.

TCP

TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other. TCP is a connection-oriented protocol, which means a connection is established and maintained until the application programs at each end have finished exchanging messages. It determines how to break application data into packets that networks can deliver, sends packets to and accepts packets from the network layer, manages flow control, and—because it is meant to provide error-free data transmission—handles retransmission of dropped or garbled packets as well as acknowledgement of all packets that arrive.

RFC 793

TRANSMISSION CONTROL PROTOCOL

4.

SMTP

SMTP (Simple Mail Transfer Protocol) is an application layer protocol. The client who wants to send the mail opens a TCP connection to the SMTP server and then sends the mail across the connection. The SMTP server is always on listening mode. As soon as it listens for a TCP connection from any client, the SMTP process initiates a connection on that port (25). After successfully establishing the TCP connection the client process sends the mail instantly.

RFC 821

SIMPLE MAIL TRANSFER PROTOCOL

5.

HTTP

HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. As soon as a Web user opens their Web browser, the user is indirectly making use of HTTP. HTTP is an application protocol that runs on top of the TCP/IP suite of protocols (the foundation protocols for the Internet).

RFC 2068

Hypertext Transfer Protocol -- HTTP/1.1
