Given that everyday business activities are heavily reliant on technology, even minor network performance issues significantly impact business productivity, performance, profitability, and customer satisfaction. In 2023 91% of companies reported experiencing at least one outage quarterly. Two-thirds of these outages cost companies more than $100,000, so network monitoring and measuring network performance should be a top priority for all companies.

In this comprehensive guide, we will outline the principles of network performance monitoring, identify important network performance metrics to focus on, and provide actionable insights to maximize your company’s network performance. 

What are Network Metrics?

The speed, dependability, effectiveness, and general health of a network are assessed using quantitative measurements called network metrics. IT teams can obtain important insights into issues by analyzing network traffic, gathering and examining metrics such as bandwidth, latency, packet loss, uptime are all effective methods to do this. 

Network administrators measure and assess these metrics to identify issues, optimize IT infrastructure management, and pinpoint areas that require improvement.

Monitoring key network metrics provides three main benefits for businesses:

  1. Visibility: Metrics reveal network behavior and resource utilization, enabling IT teams with insights into their network infrastructure.
  2. Diagnostics: Unusual patterns or deviations from established thresholds in metrics can signal underlying network issues. Metrics help pinpoint exactly where problems originate.
  3. Optimization: By establishing network performance baselines and tracking metrics over time, teams can optimize their network for peak efficiency.

What is Network Traffic Analysis (NTA)?

Network traffic analysis (NTA) uses ongoing network traffic monitoring to protect network assets and ensure network availability.

By identifying performance problems and anomalies, NTA tools enable IT teams to identify these issues and anomalies and take proactive measures to mitigate them. For example, network monitoring can detect and mitigate sudden traffic surges or large data transfers that could have a negative impact on network performance and availability.

Moreover, network monitoring tools play a crucial role in security by identifying and mitigating risks in order to enforce and maintain security standards. They scan for suspicious activity, flagging potential threats before they escalate into data breaches or system outages.

Monitoring systems assess the security of data by checking for vulnerable protocols or encryption ciphers and alerting administrators of security vulnerabilities. Using network monitoring tools to identify weaknesses in the network architecture allows IT teams to plan and implement strategies to fortify the network against potential attacks.

Step-by-Step Guide

Step-by-Step Guide

The following are the fundamental procedures for carrying out any kind of network analysis:

  • Configuring the network analyst environment
  • Adding a network dataset
  • Creating the network analysis layer
  • Adding network analysis objects
  • Setting network analysis layer properties
  • Performing the analysis and displaying the results

Step 1: Configuring the Network Analyst Environment

Network Analyst extension must be enabled before performing any network analysis.  This will display both the Network Analyst toolbar and window. Detailed steps for this are covered in “Configuring the Network Analyst” environment section.

Step 2: Adding a Network Dataset

The next step is to add a network dataset layer. This may require building the network if it doesn’t already exist. If the source features have been edited or the referencing network attributes have changed, you will need to rebuild the network dataset.

Step 3: Creating the Network Analysis Layer

A network analysis layer functions as a storage area for the inputs, properties, and results of network analysis. It contains workspace in memory, which keeps network analysis classes for both input data and analysis results. The features and records within the network analysis classes are referred to as network analysis objects. 

Some properties of the network analysis layer allow you to further define the problem you want to solve. Network analysis is always performed on network datasets. Consequently, a network analysis layer must be connected to a network dataset. 

When creating a network analysis layer using a geoprocessing tool, the network dataset is designated as a tool parameter. The network dataset must be added before the creation of the analysis layer to enable the Network Analyst to bind the analysis layer to the network dataset.

Note:

When a network dataset is added, it is referred to as a network dataset layer, or simply a network layer. Network layers represent network datasets, whereas network analysis layers represent the inputs, properties, and results of network analysis.

There are six kinds of network analysis layers:

  • Route analysis layer
  • Closest facility analysis layer
  • Service area analysis layer
  • OD cost matrix analysis layer
  • Vehicle routing problem analysis layer
  • Location-allocation analysis layer

Step 4: Adding Network Analysis Objects

Network analysis objects are features and records that serve as both inputs and outputs during network analysis. Examples include stops, barriers, routes, and facilities.

You can add network analysis objects that can be added to input classes, but not to output-only classes. The solver is exclusively responsible for creating output-only network analysis objects. For example, within a route analysis layer, the route class is output only, so route objects can only be created by the solver.

There are different ways to add objects to classes. The two most commonly chosen options are: loading multiple features into a network analysis class simultaneously, or interactively adding one object at a time.

Step 5: Setting Network Analysis Layer Properties

In addition to object specific properties, the network analysis layer possesses properties that are more general to overall analysis. These general analysis properties include the network impedance attribute to be utilized and any restriction attribute that must be followed. 

Additionally, there are properties that are unique to the kind of analysis being performed. All of these properties can be accessed and adjusted within the Layer Properties dialog box of an analysis layer.

Step 6: Performing the Analysis and Displaying the Results

After creating the analysis layer, adding the necessary input network analysis objects, and configuring the set of parameters for the analysis objects and analysis layer, it is time to solve the network problem.

Click the Solve button on the Network Analyst toolbar triggers the Network Analyst to generate the solution. This solution is then integrated into the network analysis layer. As a result, the output network analysis objects are created and the input/output objects are updated with results.

You can look at the map and double-click the network analysis objects in the Network Analyst window to inspect the results.

Conclusion
