Fundamental to network management is the ability to gather information about the status and behavior of the networked configuration, which is the function of network monitoring. Indeed, many NMS provide only a network monitoring capability. We have already examined the basic architectural and design issues of network monitoring in this week. For network management, there are five key functional areas as defined by the International Organization for Standardization (ISO). On the basis of your understanding of the topic, address the following: When discussing KPIs of network management, there are various elements that are tracked in order to give a projection of the health of the system. One of the KPIs is ‘response time’ among other indicators. Each element in a response time is one segment of the overall path an inquiry takes through a communications configuration as well as each element contributes a portion of the overall response time. Let’s examine the elements involved in a typical networking station in which up to seven elements can be observed.

Fundamental to network management is the ability to gather information about the status and behavior of the networked configuration, which is the function of network monitoring. Network monitoring involves the collection of data related to network performance, such as traffic volume, error rates, bandwidth utilization, and device availability. This information is then analyzed to identify performance issues, troubleshoot problems, and make informed decisions regarding network design and optimization.

In the field of network management, there are five key functional areas as defined by the International Organization for Standardization (ISO). These areas include fault management, configuration management, accounting management, performance management, and security management. Each of these areas plays a crucial role in ensuring the efficient and effective operation of the network.

Among the various elements tracked in network management key performance indicators (KPIs), response time is a significant indicator. Response time is the time it takes for a user-requested action to receive a response from the network. It is an essential metric as it reflects the quality of service provided by the network. A low response time indicates a more efficient and responsive network, while a high response time may imply network congestion or performance issues.

When analyzing response time, it is important to consider the different elements involved in a typical networking station. These elements contribute to the overall response time and can be observed and measured individually. In a typical networking station, up to seven elements can be identified:

1. User-End System: This is the device or application from which the user initiates a request. It can be a computer, laptop, or mobile device running an application or accessing a website.

2. Access Network: This element includes the physical and logical infrastructure that connects the user-end system to the wider network. It can be a wired or wireless network, such as Ethernet, Wi-Fi, or cellular networks.

3. Router: Routers are responsible for directing network traffic and forwarding data packets between different networks. They play a crucial role in determining the optimal path for data transmission.

4. Core Network: The core network consists of high-capacity routers and switches that form the backbone of the network. It provides connectivity between different access networks and ensures efficient data transmission.

5. Internet Service Provider (ISP) Network: The ISP network connects the core network to the wider internet. It consists of multiple routers and switches that enable data exchange with other networks.

6. Destination Network: This is the network where the requested resource or service resides. It can be a local area network (LAN) or a wide area network (WAN) connecting multiple locations.

7. Destination Server: The destination server is where the requested resource or service is hosted. It can be a web server, database server, or any other type of server depending on the nature of the request.

Overall, each of these elements contributes to the overall response time experienced by the user. By monitoring and analyzing the performance metrics of each element, network administrators can identify bottlenecks, troubleshoot performance issues, and optimize the network to provide a better user experience.
