The Network Time Protocol (NTP) is a service that allows system clocks to be synchronized (from desktops to servers). It is not only useful but also needed for many distributed applications to have synchronized clocks. As a result, if the time originates from an external server, the firewall rules must enable the NTP service.

The usage of authentication techniques in Network Time Protocol (NTP) is critical to preventing an attacker from manipulating time information. Such systems have been present for a long time, such as the Symmetric Key-based method and the Autokey approach.

In order to describe network congestion or other degraded network situations, the level of network traffic is gauged by traffic intensity. When determined, traffic intensity—also known as the traffic intensity factor—describes the state of a packet-switched network, such as one that carries TCP traffic.

The traffic intensity factor a relative measure, takes into account the average packet size, arrival rate, and available network transmission speeds. It can be calculated using the formula below:

The equation for the Traffic intensity factor is:

An IP network can be logically divided into subnetworks or subnets. 1, 16 Subnetting is the process of splitting a network into two or more networks.

Similar most-significant bit groups are used in IP addresses to address computers that are on the same subnet. As a result, the network number or routing prefix and the rest field or host identity are logically separated into two fields in an IP address. A host or network interface can be identified by the remainder field.

The Classless Inter-Domain Routing (CIDR) notation allows the routing prefix to be represented as the network's primary address, followed by a slash (/), and the prefix's bit length at the end. To give one example, the prefix is 198.51.100.0/24.
