Simple Network Management Protocol (SNMP):

The Simple Network Management Protocol (SNMP) is used to exchange management information among network devices.

• Many protocols are available to support network management, but the SNMP is the simplest, easiest, and most widely used; hence the most preferable protocol is SNMP.
  • Also SNMP is having an industry standard, formed by the Internet Engineering Task Force; which is formerly designed to manage Internet components.
  • This SNMP can be used to manage Wide Area Network (WAN) and telecommunication systems.

TCP:

TCP is connection oriented. Transfers messages across the machines connected with internet. It provides reliable service. HTTP (Hyper Text Transfer Protocol), HTTPS (Hyper Text Transfer Protocol Secure), FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and Telnet are the protocols used in TCP.

UDP:

UDP is connectionless. It sends packets to another machine. It provides unreliable service. It is used in fast and efficient transmission applications. DNS (Domain Name System), DHCP (Dynamic Host Configuration Protocol), TFTP (Trivial File Transfer Protocol), SNMP (Simple Network Management Protocol), RIP (Routing Information Protocol), VOIP (Voice Over Internet Protocol) are the protocols used in UDP.
