Network Protocols

By -

 Internet Layer Protocols:

  1. Internet Protocol (IP): Responsible for addressing and routing packets of data so that they can travel across networks and arrive at the correct destination. Examples include IPv4 and IPv6.

  2. Internet Control Message Protocol (ICMP): Used for error reporting and diagnostics in IP networks. It is often used by tools like "ping."

  3. Internet Group Management Protocol (IGMP): Used by hosts and adjacent routers to establish multicast group memberships.

Transport Layer Protocols:

  1. Transmission Control Protocol (TCP): A reliable, connection-oriented protocol used for data transfer when accuracy and order of delivery are critical.

  2. User Datagram Protocol (UDP): A connectionless protocol used when speed is more important than reliability.

Application Layer Protocols:

  1. Hypertext Transfer Protocol (HTTP): Used for transferring web pages, images, and other resources on the World Wide Web.

  2. Hypertext Transfer Protocol Secure (HTTPS): A secure version of HTTP that encrypts data between the web server and the client.

  3. File Transfer Protocol (FTP): Used for transferring files between a client and a server over a network.

  4. Simple Mail Transfer Protocol (SMTP): Used for sending email messages between email servers.

  5. Post Office Protocol (POP): Used by email clients to retrieve email messages from mail servers.

  6. Internet Message Access Protocol (IMAP): Similar to POP but allows users to store messages on the server.

  7. Simple Network Time Protocol (SNTP): Used for time synchronization between computers.

  8. Domain Name System (DNS): Resolves human-readable domain names to IP addresses.

  9. Dynamic Host Configuration Protocol (DHCP): Used for automatic IP address assignment to devices on a network.

  10. Simple Network Management Protocol (SNMP): Used for monitoring and managing network devices and systems.

  11. Telnet: Allows remote access to a device or server over a network.

  12. Secure Shell (SSH): Provides secure remote access and secure file transfer over an unsecured network.

  13. Remote Desktop Protocol (RDP): Used for remote desktop access to Windows-based systems.

  14. File Transfer Protocol Secure (FTPS): A secure version of FTP that encrypts data during transfer.

  15. Secure Sockets Layer (SSL) / Transport Layer Security (TLS): Used to secure data transfer over networks, providing encryption and authentication.

  16. Simple Object Access Protocol (SOAP): Used for exchanging structured information in the implementation of web services.

  17. Border Gateway Protocol (BGP): Used to exchange routing and reachability information between autonomous systems (ASes) on the internet.

  18. Trivial File Transfer Protocol (TFTP): A simple file transfer protocol often used for network booting and firmware updates.

  19. Network Time Protocol (NTP): Used for clock synchronization between computer systems over packet-switched data networks.

  20. Lightweight Directory Access Protocol (LDAP): Used for accessing and managing directory information services.

  21. Point-to-Point Protocol (PPP): Used to establish a direct connection between two nodes.

  22. Virtual LAN (VLAN) Trunking Protocol (VTP): Used for managing VLAN configurations in a network.

  23. File Transfer Protocol over SSL (FTPS): A secure version of FTP that uses SSL/TLS for encryption.

  24. Internet Small Computer System Interface (iSCSI): Used for linking data storage facilities over an IP network.

  25. Media Access Control (MAC) Addresses: Used to uniquely identify network devices at the data link layer.

  26. Network File System (NFS): Allows remote file access and sharing across a network.

  27. Server Message Block (SMB)/Common Internet File System (CIFS): Used for file and printer sharing in Windows-based networks.

  28. Real-Time Transport Protocol (RTP) and Real-Time Control Protocol (RTCP): Used for real-time data transfer, especially in voice and video communication.

  29. Extensible Messaging and Presence Protocol (XMPP): Used for instant messaging and presence information.

  30. BitTorrent Protocol: A peer-to-peer protocol used for sharing large files.

  31. WebRTC (Web Real-Time Communication): Used for real-time communication in web browsers, including video conferencing and VoIP.

  32. Internet Key Exchange (IKE): Used for setting up a Virtual Private Network (VPN) tunnel.

  33. Network Address Translation (NAT): A technique used to modify network address information in packet headers while in transit.

  34. Multipurpose Internet Mail Extensions (MIME): Extends email messages to support text in character sets other than ASCII, as well as attachments of audio, video, images, and application programs.

Common Networking Protocols TCP - TCP breaks data into manageable packets and tracks information such as source and destination of packets. It is able to reroute packets and is responsible for guaranteed delivery of the data. IP - This is a connectionless protocol, which means that a session is not created before sending data. IP is responsible for addressing and routing of packets between computers. It does not guarantee delivery and does not give acknowledgement of packets that are lost or sent out of order as this is the responsibility of higher layer protocols such as TCP. UDP - A connectionless, datagram service that provides an unreliable, best-effort delivery. ICMP - Internet Control Message Protocol enables systems on a TCP/IP network to share status and error information such as with the use of PING and TRACERT utilities. SMTP - Used to reliably send and receive mail over the Internet. FTP - ...
