Network Speed Uncovered: What Is It Really & How to Measure It

When we talk about network performance, one metric that comes up constantly is "network speed." It's the measure of how fast your applications run, how swiftly you can transfer data, and, essentially, how responsive your digital world is. Speed in networking is like the speedometer in a car—it tells you how quickly things are moving.

However, network speed isn't just about raw velocity. It's a blend of various underlying factors such as latency (the delay in data transmission), jitter (the variability in packet arrival times), packet loss (missing data during transmission), and the theoretical bandwidth available for data transfer. It's like a recipe where each ingredient contributes to the final flavour.

When your network boasts high bandwidth and optimal performance, you expect to see that reflected in your speed tests. These tests validate the overall performance of your network, ensuring you're getting what you pay for in terms of speed and reliability. If there's a discrepancy, it could indicate either a network performance issue or intentional throttling.

In this article, we’re going to be breaking down everything you need to know about network speed - what it is, why it’s important, what affects it, and how to monitor it.

Network speed refers to the rate at which data can be transmitted or received over a network, typically measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps). It reflects how quickly information can travel between devices, servers, or endpoints within a network or across the internet.

In the world of network monitoring, speed remains a crucial metric. It's a great indicator of whether you're getting the Internet performance and network bandwidth promised in your Service Level Agreement (SLA).

Understanding what contributes to network speed empowers businesses to optimize performance and ensure you get the most out of your network and your Internet service. So on that note:

Network speed is typically measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps).

1. Bits per Second (bps): This is the smallest unit of measurement and represents the number of individual bits transmitted or received in one second. It's often used for very low-speed connections or in discussions about the fundamental speed of data transmission.
2. Kilobits per Second (kbps): One kilobit is equal to 1,000 bits. Kbps is commonly used for measuring speeds in dial-up connections or early broadband technologies.
3. Megabits per Second (Mbps): One megabit is equal to 1,000 kilobits, or 1,000,000 bits. Mbps is widely used for measuring speeds in modern broadband and networking technologies, including DSL, cable, fibre-optic, and wireless connections.
4. Gigabits per Second (Gbps): One gigabit is equal to 1,000 megabits, or 1,000,000,000 bits. Gbps is used for high-speed connections such as fibre-optic networks, high-performance data centers, and enterprise-grade networking equipment.

Network speed can be measured using various tools and methods, including:

• Speed Test Websites: Online platforms that measure download and upload speeds between your device and a test server, providing results in Mbps or Gbps.
• Network Monitoring Software: Network Monitoring Tools that continuously monitor network traffic and provide real-time data on network speed, bandwidth usage, latency, and other performance metrics. Some of these tools also include more specific Network Speed Monitoring tools.
• Command Line Tools: Command-line utilities like 'ping' and 'traceroute' can also provide insights into network speed and latency between devices.

Alright, let's clear up a common mix-up in the networking world. Many people mistakenly use these terms interchangeably because they are related. However, they represent different aspects of network performance:

• Network Speed: The most commonly spoken about metric when it comes to network and application performance, refers to the speed at which data is transferred between two devices on a network.
• Network Bandwidth: The maximum amount of data that can be transmitted over a network or communication channel in a given period.
• Throughput: The actual amount of data that is transmitted over a network or communication channel in a given period.

They're like different parts of a water pipe system, and knowing the difference can save you from a lot of head-scratching moments.

1. Network Speed: Think of network speed as the rate at which water flows through the pipe, measured in gallons per minute (GPM). In the digital world, network speed is how quickly data moves from one point to another, like the speed at which water moves through a pipe.

2. Bandwidth: Bandwidth is like the diameter of the pipe. A wider pipe (higher bandwidth) can accommodate more water (data) flowing through it at once. Bandwidth is typically measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps). So, a higher bandwidth means more data can flow through the network at a given time.

3. Throughput: Throughput, on the other hand, is the actual amount of water that successfully reaches its destination at the end of the pipe. In networking terms, throughput is the amount of data that is successfully transmitted over the network in a given period of time. It's like measuring how much water actually makes it through the pipe to fill a container at the end.

While a wider pipe (higher bandwidth) can potentially allow for faster flow (network speed) and more water (throughput), they are distinct measurements that collectively determine the efficiency and capacity of a network.

Most of the time, people will measure their network speed by running speed tests using a speed test tool on a website. But doing that only tells you how fast your network is performing when you run that speed test, which isn’t super helpful when measuring performance or quality.

When it comes to understanding network speed, there's more to it than just how fast data travels. There are so many different factors and metrics that can impact your network speed and slow down your Internet - and just performing an online speed test won’t tell you what they are.

So let’s go over the core components that make up network speed, exploring the nuances of latency, jitter, packet loss, theoretical bandwidth, throughput, and Quality of Service (QoS).

1. How Latency Affects Network Speed: Understanding Delay in Data Transmission

Latency refers to the delay that occurs when data is sent from one point to another in a network. It is measured in milliseconds (ms) and includes various types of delays:

• Propagation Delay: The time it takes for a signal to travel from its source to its destination.
• Transmission Delay: The time it takes to push bits into the transmission medium.
• Processing Delay: The time it takes for routers, switches, and other network devices to process and forward data.
• Queuing Delay: The time data spends in network queues waiting to be processed.

High latency results in delays in data transmission, leading to slower network speeds and reduced responsiveness. Applications that require real-time interaction, such as online gaming and video conferencing, are particularly sensitive to latency. Lower latency is essential for achieving faster network speeds and improving the overall user experience.

2. How Jitter Affects Network Speed: Exploring Variability in Packet Arrival Times

Jitter refers to the variation in packet arrival times, leading to irregularities in data transmission. It can result from network congestion, varying path lengths, or inconsistent transmission rates. Excessive jitter can cause packet loss, degraded audio/video quality in communication applications, and disruptions in data flows.

3. How Packet Loss Affects Network Speed: Impact on Data Integrity

Packet loss occurs when data packets fail to reach their destination due to network congestion, errors, or hardware issues. It can lead to data retransmissions, increased latency, and degraded performance. Packet loss affects the integrity and completeness of transmitted data, impacting applications that require reliable data delivery, such as file transfers, VoIP calls, and video streaming.

Packet loss can significantly impact network speed by requiring data retransmissions, increasing latency, and reducing overall throughput. It affects the integrity and completeness of data transmission, leading to performance degradation in applications that require reliable data delivery.

4. How Theoretical Bandwidth Affects Network Speed: Capacity for Data Transfer

Theoretical bandwidth refers to the maximum data transfer rate a network connection can achieve under ideal conditions. It is determined by the physical properties of the network medium, such as cable type, fibre optics, or wireless technology.

While it indicates the network's capacity for data transfer, actual network speed may be lower due to factors such as network congestion, latency, and packet loss. Optimizing network infrastructure and addressing performance bottlenecks are key to realizing higher network speeds close to theoretical bandwidth.

5. How Throughput Affects Network Speed

Throughput is the actual amount of data that successfully traverses the network in a given time period. It represents the effective data transfer rate and is influenced by factors such as latency, packet loss, network congestion, and available bandwidth that directly impact throughput and, consequently, network speed.

6. How Quality of Service (QoS) Affects Network Speed

Quality of Service (QoS) mechanisms prioritize certain types of traffic to ensure consistent and reliable performance for critical applications. By allocating network resources based on predefined policies, QoS helps minimize latency, reduce packet loss, and optimize throughput for prioritized traffic. Implementing effective QoS policies is crucial for maintaining high-speed network connections and meeting performance requirements for mission-critical applications.

• Testing Different Devices and Locations: Conduct speed tests on multiple devices and at different locations within the network to pinpoint potential issues specific to certain devices or areas.
• Consulting with Internet Service Provider (ISP): If speed issues persist, contact the ISP for assistance. They can diagnose network problems, perform line tests, and recommend solutions to improve speed and performance.

By conducting speed tests, interpreting the results accurately, and troubleshooting speed issues effectively, users can assess network performance, identify potential problems, and optimize their network connections for faster and more reliable data transmission.

While speed tests are the most common method for measuring network speed, they only give you a partial understanding. Speed Tests will give you the exact speed measurement between two points in your network during a specific period of time, but they don't give you an overall view of performance or speed-related issues.

Additionally, speed tests create congestion in your network, which can affect all the traffic on the Internet connection. This may be okay for a residential test, but in a business, it may mean severely interrupting VoIP calls or Video conferences.

With so many factors affecting network speed, it’s clear that network speed isn’t just about how much bandwidth you have available. To truly pinpoint and resolve speed-related problems, you need a monitoring solution that delves into these intricacies. It's about more than just confirming speed—it's about understanding the underlying factors influencing it.

That’s where Network Monitoring comes in.

To accurately measure end-to-end network speed and identify performance issues, Obkio's Network and Speed Monitoring Tool monitors both network performance and speed throughout your whole network.

Once you've deployed Monitoring Agents within your network, you can continuously monitor network speed using Speed Tests. Obkio facilitates speed tests between any deployed monitoring agents in your network.

Obkio's comprehensive network performance and speed monitoring tool enable you to conduct Speed Tests and correlate the data with other network performance metrics for in-depth analysis.

With Obkio's scheduled speed tests, you can set them to run at specific intervals, such as hourly, every 2 hours, every 3 hours, and so on. Each scheduled test randomly selects a minute within the hour to evenly distribute speed tests.

The speed measured in these tests represents the available throughput, which is the unused and accessible bandwidth when conducting a speed test. For instance, if your network has a bandwidth of 100 Mbps but your current throughput is 50 Mbps, the speed test assesses how much of the remaining 50 Mbps is being utilized.

As speed tests, regardless of the type used for network speed monitoring, invariably induce network congestion, Obkio presents two Speed Test options:

I. On-Demand Speed Tests

These tests can be manually initiated when troubleshooting network slowdowns. Limiting their use to troubleshooting helps minimize the congestion they generate on your network.

II. Scheduled Speed Tests

For automated network speed monitoring, Obkio provides Scheduled Speed Tests that can be set to run at specific intervals between two chosen monitoring agents. For instance, many clients opt to schedule Speed Tests at full connection speed overnight to avoid disrupting employees during working hours, even if they cause congestion.

Additionally, tests can be scheduled at 50% of the connection speed during the workday to reduce frequency and minimize disruption.

At this stage, you'll have an end-to-end network monitoring and speed testing solution to measure your network's speed, along with other metrics impacting your expected speed.

Obkio’s schedules and on-demand Speed Tests will give you the exact speed measurement between two points in your network. It's important to know your expected theoretical bandwidth and then compare it with your actual speed to gauge if you're meeting expectations.

When you conduct a speed test, you're only measuring speed between two specific points, from point A to point B. However, to understand your network's true performance, Obkio analyzes metrics like throughput, packet loss, and latency on our Network Response Time Graph to give you visibility of your overall network performance and highlight when network issues affecting your network speed occurred.

• Throughput: Throughput represents the actual amount of data successfully transferred over the network in a given time frame. It indicates the effective data transfer rate and reflects the network capacity to handle data traffic. By monitoring throughput, you can assess how efficiently data is being transmitted across your network.
• Packet Loss: Packet loss occurs when data packets fail to reach their destination, either due to network congestion, errors, or hardware issues. Monitoring packet loss helps identify potential network issues that may impact data integrity and reliability. Excessive packet loss can lead to performance degradation and affect user experience.
• Latency: Latency refers to the delay in data transmission between two points in the network. It includes various types of delays, such as propagation delay, transmission delay, processing delay, and queuing delay. High latency can result in slower response times and decreased network performance, particularly in real-time applications.

By analyzing these metrics on the Network Response Time Graph, Obkio provides visibility into your network's overall performance trends and highlights instances when network issues impacting network speed occurred. This holistic approach helps you identify and address potential bottlenecks, optimize network configurations, and ensure optimal performance across your network infrastructure.

So keep in mind that command line tools, like stand-alone speed tests, only give you a partial view of performance and should be used in combination with more comprehensive network monitoring solutions if you want to go further into understanding and troubleshooting network speed.

Ping is a simple utility used to test network connectivity between two devices. It sends ICMP (Internet Control Message Protocol) echo request packets to a target device and waits for ICMP echo reply packets in response.

• Measurement: Ping measures latency, also known as round-trip time (RTT), which is the time taken for a packet to travel from the source device to the target device and back. Lower latency values indicate faster network responsiveness.
• Usage: In the command line interface, you can use the "ping" command followed by the IP address or hostname of the target device. For example, "ping google.com" or "ping 8.8.8.8" sends ping requests to Google's servers.

Traceroute is a network diagnostic tool used to trace the route taken by data packets from the source device to the target device or server. It shows the sequence of routers or network devices traversed along the path.

• Measurement: Traceroute measures hop-by-hop latency and identifies the network path taken by packets. It displays each router's IP address, hostname (if available), and round-trip time (RTT) for each hop.
• Usage: In the command line interface, use the "traceroute" command (or "tracert" in Windows) followed by the IP address or hostname of the target device. You can also use Obkio’s Visual Traceroute tool for a more detailed, visual traceroute experience.

Benefits: Ping and traceroute are quick and easy-to-use tools for basic network diagnostics. They provide valuable insights into network latency, routing paths, and connectivity issues.

Limitations: These tools primarily measure latency and routing information. They may not provide detailed information about packet loss, throughput, or other performance metrics. For comprehensive network monitoring and troubleshooting, specialized network monitoring tools like Obkio offer more advanced features and insights.

In summary, ping and traceroute are fundamental command line tools for measuring network speed, latency, and diagnosing connectivity issues, making them valuable tools for basic network troubleshooting and diagnostics.

Determining what qualifies as good network speed depends on various factors, such as the type of activities performed, the number of users, and specific requirements.

• Update Software: Ensure that networking software, firmware, and operating systems are up to date with the latest patches, updates, and optimizations. Software updates can address performance issues, security vulnerabilities, and compatibility issues that affect network speed.

If network speed issues persist despite internal optimizations, contact your Internet Service Provider (ISP) to investigate and troubleshoot potential issues on their end.

• Performance Testing: Request performance tests from your ISP to measure actual network speeds and identify any discrepancies between expected and actual speeds.
• Check Service Status: Verify the status of your ISP's network infrastructure, service outages, or maintenance activities that may affect network speed. Monitor service status updates and notifications from your ISP for real-time information.

• Upgrade Internet Plan: Consider upgrading to a higher-speed Internet plan offered by your ISP to increase available bandwidth. Choose a plan with higher download and upload speeds that meet your organization's requirements for data-intensive applications, streaming, and communication.
• Dedicated Connection: Explore options for dedicated Internet connections or fiber-optic services that offer symmetrical upload and download speeds, low latency, and high reliability for mission-critical operations.
• Load Balancing: Implement load balancing solutions to distribute network traffic across multiple Internet connections or paths, optimizing bandwidth utilization and improving network speed and performance.

• Router and Switches: Upgrade to high-performance routers and switches that support faster data transfer rates and advanced networking features such as Gigabit Ethernet or 10 Gigabit Ethernet.
• Network Interface Cards (NICs): Install Gigabit Ethernet or faster NICs on devices to improve network connectivity and throughput.

• QoS (Quality of Service): Configure Quality of Service settings to prioritize critical traffic such as VoIP calls, video conferencing, or real-time applications, ensuring they receive sufficient bandwidth and lower latency.
• Bandwidth Allocation: Allocate bandwidth effectively based on application requirements and user priorities. Limit bandwidth-intensive applications to prevent them from consuming excessive network resources.

• Wireless Channel Selection: Choose the least congested wireless channels (2.4GHz and 5GHz) to minimize interference and improve Wi-Fi performance.
• Signal Strength: Position wireless access points strategically and use signal boosters or repeaters to enhance coverage and signal strength in areas with weak Wi-Fi signals.

Implement traffic shaping, rate limiting, or packet prioritization techniques to manage and control network traffic, preventing congestion and ensuring smoother data transmission. Or use content filtering solutions to block or restrict access to non-business-related websites and applications that consume network bandwidth unnecessarily.

By troubleshooting network speed problems internally, reaching out to your ISP for external issues, and considering options to increase bandwidth, you can significantly improve the performance and reliability of your network. These proactive steps not only address current speed issues but also prepare your network for future growth and demands. With a faster and more efficient network, you can enhance productivity, communication, and overall user satisfaction within your organization.
