What are NTP and SNMP network protocols?


Chances are you’ve heard of network protocol in the past, but you probably have no idea what it is. Of course, for now, we can say that there are different types of network protocols designed for specific use cases.

We won’t explain all the different types of network protocols in this article, but of course we will talk about two of them. They are SNMP (Simple network management protocol) and NTP (Network time protocol).

What are NTP and SNMP Network Protocols

The idea here is to make sure that by the end you should have a deeper understanding of what these protocols are, especially for those who are planning to enter the world of networking in the near or distant future. Don’t make mistakes; you are about to learn a lot.

  1. What is a computer network?
  2. What are network protocols, you ask?
  3. SNMP (Simple Network Management Protocol) explained
  4. NTP (Network Time Protocol) explained

Let’s discuss it from a more detailed point of view.

1]What is a computer network?

In short, a computer network is a collection of computer systems connected to share resources and communicate.

2]What are network protocols?

Okay, so a network protocol contains all the instructions and standards for devices communicating with each other, including several ways that devices can connect and identify themselves.

It should be noted that some networks have the capability of acknowledging messages and compressing data for network communication, which provides a service with high performance and reliability.

3]SNMP (Simple Network Management Protocol) explained

From our understanding, Simple Network Management Protocol (SNMP) is an application layer protocol primarily used to manage network devices. When it comes to valuable network data coming from switches, routers, servers, printers and more, SNMP is able to handle it all.

It should also be noted that there are two components within a network managed by SNMP. They are as follows:

  • Network management station (NMS): OK, so NMS is designed to collect SNMP information by asking devices on the network to reveal specific data. Not only that, but devices on your network can notify the NMS of potential issues by sending an SNMP alert, also known as a trap. Keep in mind that the NMS software runs only on the administrative computer.
  • Agent: The interesting thing about Agent software is that it runs on managed devices that report data to SNMP through NMS.

4]NTP (Network Time Protocol) explained

NTP, like SNMP, is also an application layer protocol. However, it is used for time synchronization on a TCP / IP network between hosts. The overall design of NTP is to ensure that all computers on a particular network agree to the same clock time.

Time synchronization is necessary because the differences can complicate life for network administrators. For example, suppose the Active Directory domain controller and the host computer cannot agree on a time simultaneously. In this case, you might have trouble signing in to your AD domain.

Note that NTP uses a hierarchical system of time sources. At the very top of the structure are precise sources such as GPS or atomic clocks. These clocks are widely known as Stratum 0 servers, which are directly linked to Stratum 1 servers as well as all computers running NTP that provide time to Stratum 2 servers.

Note that NTP uses a client-server architecture where one host is built as an NTP server while the other hosts are configured as NTP clients.
