Program Plan Intro

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.

Students have asked these similar questions
In Section 5.7 we saw that it was preferable to transport SNMP messages in unreliable UDP datagrams. Why do you think the designers of SNMP chose UDP rather than TCP as the transport protocol of choice for SNMP?
We said that a program should use UDP for a transport layer protocol because UDP has better control over when the data is sent to a section and when (the TCP). A. Why does the program have more power about which data is sent into a segment?
When it comes to transport layer protocols that can be relied on to provide services, TCP is a full duplex option. What does it mean when we say that something is full-duplex, connection-oriented, and reliably delivered?
