What is Latency ?| Definition of the Concept of Network Latency

In our digitally dominated world, the term ‘latency’ is frequently mentioned in discussions about internet speed and network performance. Often linked to connection speed and bandwidth, latency is a crucial factor that affects our online interactions, gaming sessions, and even the way we communicate. But what exactly is latency, and why is it so important? Let’s demystify this network term and understand its implications across different industries.

What is Latency?

Latency, in the realm of networks, describes the total time it takes for a data packet to travel from one point to another. In essence, it’s the delay from the moment you perform an action online, like clicking a link, to the moment you see the result, such as a loaded webpage. This delay is typically measured in milliseconds (ms), and the lower the latency, the quicker the network response. This metric is especially critical in fields requiring real-time data exchange, such as fluid dynamics, high-frequency trading, and high-performance computing, where delays can drastically impact outcomes.

Types of Latency

In the world of networking, latency is a crucial factor that can greatly impact the performance and user experience of various applications. There are different types of latency, each with its own unique characteristics and effects. Let's explore two main types of latency: network latency and application latency.

Network Latency

Network latency refers to the delay caused by the physical distance between the source and destination. This means that the longer the distance, the higher the latency. However, network congestion and the quality of the network infrastructure can also contribute to network latency. Factors like the physical distance between the source and destination, network congestion, and the quality of the network infrastructure (including routers, switches, and cables) can all influence network latency.

The impact of network latency is significant across different industries. In the telecommunications industry, high latency can result in poor call quality and delays in voice communication. Online gaming heavily relies on low latency to ensure real-time responsiveness and smooth gameplay. Even in robotics, low latency is essential for real-time control and feedback, enabling precise movements and coordination.

Application Latency

On the other hand, application latency refers to the delay caused by the time it takes for a device or system to process the data it receives. This type of latency can be influenced by factors such as the processing power of the device and the complexity of the task or application being executed. High application latency can result in slower response times, leading to a poor user experience. Applications may become unresponsive or exhibit delays in performing desired actions.

Understanding the different types of latency and their effects is crucial for optimizing network performance and providing a seamless user experience. By addressing network latency and minimizing application latency, businesses can ensure faster data transmission, improved responsiveness, and enhanced user satisfaction.

Why latency is so important in 2024 ?

As businesses evolve through digital transformation, their reliance on cloud-based applications, AI and IoT (Internet of Things) devices has made network performance a linchpin of operational efficiency. Latency affects not just the speed of operations but also influences user experience and customer satisfaction. In an age where data is king, the ability to swiftly collect, analyze, and act on information is paramount. High latency can erode the advantages of increased network capacity, making investments in network infrastructure less fruitful.

Latency vs. Bandwidth: Clearing the Confusion

There’s often confusion between the terms latency, bandwidth, and connection speed. While service providers advertise their networks as having speeds of 50 Mbps, this figure refers to bandwidth—the amount of data that can be transferred per second—not the actual speed at which the data travels. Latency, on the other hand, measures how quickly data can be transferred, akin to the speed of a car on a highway. Here you can find our article on bandwidth: here.

The Highway Analogy

To illustrate, imagine a highway: bandwidth is equivalent to the number of lanes on the road, while latency is how fast the cars can travel from point A to point B. A 5-lane highway (high bandwidth) with few cars can allow for a faster journey (low latency), compared to a congested two-lane road (lower bandwidth) where vehicles are slowed down (high latency).

Which applications require low and stable latency ?

While every organization benefits from reduced latency, its importance escalates in specific fields and applications. Below are highlighted examples:

  • Streaming Analytics Applications For streaming analytics applications, such as live financial trading platforms, eSports streaming, and interactive live broadcasts, processing and analyzing vast streams of real-time data from various sources is critical. These applications, akin to platforms like Twitch or YouTube Live, rely on up-to-the-second accuracy to inform viewer decisions and maintain engagement. Delays or lags, in this context, can have significant financial implications or diminish user experience, emphasizing the necessity for low-latency networks.

  • Real-Time Data Management Enterprise systems integrating real-time data from diverse inputs, including software interfaces, cloud databases, and IoT sensors, exemplify this need. Using technologies like change data capture (CDC), these systems—similar to data management platforms used by companies like Salesforce or SAP—aggregate and process information instantaneously. Latency issues can disrupt these operations, affecting everything from customer relationship management to supply chain logistics.

  • API Integration The interconnectivity between systems via application programming interfaces (API) is foundational to modern software architecture. This is evident in services like Google Maps on delivery tracking websites or payment gateways integrated into e-commerce platforms like Shopify. When network latency delays API responses, it can stall these integrated systems, leading to operational inefficiencies or lost transactions.

  • Video-Enabled Remote Operations Remote operations that depend on video feed, such as telehealth services through platforms like Teladoc or remote learning environments using Zoom or Microsoft Teams, require real-time interaction capabilities. In such contexts, high latency can hinder the effectiveness of remote diagnostics, education delivery, and even remote piloting of drones for critical missions, underscoring the critical nature of low-latency networks to avoid delays that could compromise outcomes.

Which industriees need low network latency ?

Certain sectors are inherently more sensitive to latency, where even the smallest delay can have significant repercussions:

  • Financial Services: In the world of high-frequency trading, a millisecond's delay can lead to substantial financial loss.

  • Healthcare: Remote surgeries and patient monitoring rely on real-time data, where delays can affect patient care.

What Are the Causes of Network Latency?

Before diving into how latency influences various sectors, it’s crucial to understand what factors can contribute to network delay. Latency can be affected by a myriad of elements, each playing a significant role in the efficiency of data transmission.

  • Distance: The physical distance between the source and destination of the data can greatly influence latency. Data has to travel via various networks and possibly even under oceans to reach its destination, and the greater the distance, the longer it will take.

  • Medium: The type of medium the data is traveling through—be it copper cables, fiber optics, or wireless signals—also affects latency. For instance, fiber optics generally provide lower latency compared to traditional copper cable connections.

  • Network Congestion: Much like traffic on a highway, data packets can experience delays due to congestion on the network. When too many devices or transfers are occurring simultaneously, it can slow down the overall speed of the network, increasing latency.

  • Routing and Switching: The route that data takes through the network can introduce delay. Each time data is routed or switched through a different path, additional processing time can increase latency.

  • Server Processing Time: The speed at which a server can process a data request also impacts latency. If a server is slow to respond or is handling multiple requests at once, it can delay the response time.

Understanding these factors is essential for diagnosing latency issues and improving network performance. Now, let’s see how latency plays out in different industries.

Industry Impacts Latency is not just a concern for network engineers; it impacts various sectors:

  • Telecommunications: In voice and video calls, low latency is essential for clear and uninterrupted communication.

  • Online Gaming: Gamers require low latency for real-time responsiveness and competitive play.

  • Robotics: For precise and accurate operations, especially in medical and manufacturing robotics, low latency is critical for synchronizing commands and feedback.
