Network documentation is a form of technical documentation, the goal of which is to maintain computer networks. [1] It contains information about how the network is built, how it should perform, and where to troubleshoot problems.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]
A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network management systems. [2] Fault management systems may use complex filtering systems to assign alarms to severity levels.
The end-to-end principle is a design principle in computer networking that requires application-specific features (such as reliability and security) to be implemented in the communicating end nodes of the network, instead of in the network itself.
The basic study of system design is the understanding of component parts and their subsequent interaction with one another. [ 1 ] Systems design has appeared in a variety of fields, including sustainability, [ 2 ] computer/software architecture, [ 3 ] and sociology.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Interactive function step; Information function step; System timing step; System implementation step; Later, some steps were combined to create a method with only three steps.
