What is Low Latency? How to Reduce Network Latency

Latency is the time it takes for data to travel from one point to another within a network. The longer it takes, the higher the latency. Similarly, the less time data spends traveling, the lower the latency and the faster networking tasks can be. So, the goal for every network administrator is to keep latency low.

Low latency, therefore, describes a network that processes a high volume of data messages with minimal delay. Such a network is crucial for tasks like video conferencing, online gaming, and financial transactions where delays can negatively impact the user experience.

Every part of the network plays a role in maintaining low latency, from cables to routers to software configurations. Even the physical distance data travels matters. Reducing latency means optimizing the entire network ecosystem.

Why low latency is crucial for company networks

Low latency is crucial to business efficiency. Think about it. Every time you hop on a video call, any delay is a disruption. Conversations should flow naturally. Low latency makes this possible by ensuring our voices and ideas travel quickly. 

Quick communication means decisions are made faster, and collaboration is seamless. When team members can discuss and resolve issues in real time, operations simply run smoother.

Saves time and keeps teams focused on their tasks

Now, consider your files and documents stored on the server. We all know how frustrating it is to wait for a file to load or download. With low latency, these annoyances disappear. Files become accessible almost instantly. This immediate access saves time and keeps you focused on your tasks rather than waiting around.

Let’s talk about the finance department. When every millisecond can impact a transaction's success, speed is everything. Low latency networks mean trades are executed in the blink of an eye. 

This quick action reduces risks and can lead to significant gains. It's like having a lightning-fast broker who acts the moment you say go. This speed lets us capitalize on opportunities that slower networks might miss.

Makes remote work efficient and hassle-free

When it comes to cloud services, low latency is crucial. Even though your data is stored miles away, it seems it’s right at your fingertips. You can edit a cloud document as if it were on your local drive. This experience makes remote work efficient and hassle-free, keeping you connected and productive no matter where you are.

Boosts the customer experience

If customers don’t enjoy their experience with your product or your customer support, they will leave you for your competitors. Picture this: you're on a video call with a client. 

Low latency ensures there's no awkward lag. It's like sitting across the table from them, even if they're on another continent. This real-time interaction helps build rapport and trust. Clients feel heard and valued when your responses are swift and uninterrupted. 

Now, consider the customer using your online platform to make a purchase or check their account. With low latency, pages load in the blink of an eye. There's no waiting, just seamless interaction. 

It's like walking into a store and having everything you need right at your fingertips. This speed keeps customers happy and engaged, reducing the chance they'll click away in frustration.

For your clients using cloud-based services, the benefits are just as clear. Low latency makes working with remote applications feel local. Imagine accessing data stored miles away at the same speed as if it were on your computer. 

This efficiency keeps work flowing smoothly, no matter the distance. Users get things done quickly and with less hassle. That convenience is something your customers notice and appreciate.

In every interaction, low latency elevates the customer experience. It removes barriers, creating a seamless connection between you and your users. It's this kind of responsiveness that leaves a lasting impression and keeps customers coming back for more.

Factors affecting network latency

Network infrastructure

Achieving low latency is about squeezing out every possible millisecond of delay. It’s not just about having fast internet; it’s the entire backbone that supports the speed. 

Take fiber optic cables, for example. They’re the go-to for a low-latency setup for many people because they transmit data at the speed of light. Copper cables just can’t compete.

Now, let’s talk about hardware, which is the backbone of any network. Up-to-date routers and switches are crucial. These devices direct data packets efficiently to their destinations. 

If you use outdated equipment, the experience will be like having traffic lights that are always red. It’s slow. Everything halts. So, it’s crucial to ensure your routers and switches are maintained and configured properly. This keeps data flowing smoothly.

You also can’t overlook the role of software. Efficient protocols and algorithms optimize how data is processed and transmitted. For example, in high-frequency trading, every microsecond counts. So, you must ensure signal processing is fine-tuned to keep latency as low as possible. This tweaking allows businesses to execute trades or process transactions rapidly, giving them a competitive edge.

Lastly, always think strategically about server placement. By positioning servers closer to users, especially in different global regions, you can minimize data travel distance. 

This strategy is particularly important for companies with international clients. If a server is closer, say in Tokyo instead of San Francisco, the user in Japan experiences far less latency. It’s like having a local server, making everything faster and more efficient.

Bandwidth and throughput

Bandwidth is the maximum amount of data that can be transmitted over a network in a given time frame. Think of it as the width of a highway. 

The wider the highway, the more cars—or data packets—can travel at once. But bandwidth alone isn't enough. Throughput is what actually gets delivered, like how many cars make it to their destination on time.

Take a busy office where everyone is sending emails and video conferencing simultaneously. If the network only has a small bandwidth, everything slows down, like a traffic jam. But with high bandwidth, data can flow freely, reducing delays and improving the user experience. 

For instance, a company might upgrade to a 1 Gbps connection to ensure smooth video calls and quick file transfers, thereby maintaining low latency.

However, just having a high bandwidth doesn’t guarantee low latency. That's where throughput comes in. If there's congestion or interference, throughput drops, even if bandwidth is high. It’s like cars stuck on a wide highway due to an accident blocking lanes. 

Distance and propagation delay

Propagation is the time it takes for a signal to travel from sender to receiver. This delay depends on how fast the signal moves and the distance it covers.

The farther data has to travel, the longer it takes to get there. Imagine you're on a phone call to someone halfway across the globe. There will be a slight delay in your conversation. That's propagation delay in action. 

Take an email sent from New York to Tokyo. This message zips across continents, under oceans, and through numerous network nodes. The physical distance causes noticeable latency. 

That's why global companies strategically place their servers closer to users. If you are in Asia accessing a server in Europe, the data takes longer to reach you, compared to a server located in Asia. 

Even with fiber optic cables, known for their speed, distance still matters. These cables do a great job because they transmit data at fast speeds. But the Earth's sheer expanse means data still takes time, albeit a very short one, to travel. If your server is right next door, data travels almost instantly. However, if it's miles away, even the fastest cables can't defy basic physics.

Network  congestion

When multiple devices connect and try to move data through a network all at once, the network gets congested and everything slows down. This happens a lot in busy office settings, especially when everyone's online simultaneously, like right before a big meeting or deadline. 

To tackle congestion, companies often invest in more bandwidth, which is like adding more lanes to that highway. By boosting bandwidth, data packets can travel more freely, reducing the chances of a digital traffic jam. But that's only part of the solution. Even with lots of bandwidth, if the network isn't managed properly, congestion can still occur.

The role of network virtualization in achieving a low-latency network

Network virtualization abstracts physical networking hardware into virtual resources. Think of it as creating a virtual map on top of a real cityscape, where the map can be manipulated for optimal traffic flow without changing the actual streets. This abstraction allows you to manage and optimize your network resources efficiently, making a significant impact on reducing latency.

Transforms how you handle data traffic

Imagine having the ability to create virtual networks that are tailored to specific applications or departments. For instance, your finance team benefits from a dedicated virtual network that prioritizes their high-speed trading operations. 

This setup ensures that their data packets zoom through the network without unnecessary detours. It's like having a VIP lane on a highway, cutting through traffic to reach the destination faster.

Another real-world benefit is seen with your remote teams who rely heavily on cloud resources. By using network virtualization, we create virtual environments that mimic our on-premises infrastructure. 

This means when your remote employees access shared files or applications, they experience the same low-latency service they would in the office. It’s like giving everyone their express train directly to their work desk, no matter where they are.

Allows you to scale your resources dynamically

With a virtualized network, when there's a surge in demand, such as during a product launch or a big event, you can spin up additional virtual resources instantly. This flexibility minimizes latency since you prevent network congestion before it even begins.

Creating and managing virtual networks tailored to your specific needs maintains the high-speed efficiency that drives your business success. Virtualization keeps your network nimble and responsive, giving you the agility to adapt and excel in any situation.

Network virtualization techniques and tools that can help minimize latency

Virtual Local Area Networks (VLANs). 

VLANs are like creating separate lanes on a highway for different types of data traffic. You can use them to segment network traffic by department. So, each department gets a dedicated sub-network. This segmentation ensures each type of data travels without interference, reducing congestion and lowering latency.

Network Functions Virtualization (NFV)

This technique replaces traditional hardware-based networking functions with software-based ones. Imagine turning bulky physical appliances like routers and firewalls into flexible software solutions. You can leverage NFV to quickly deploy and manage network services that adapt to your needs. 

For example, during a major event or product launch, you can instantly deploy additional virtual firewall instances. This agility helps maintain optimal performance, even under heavy load, ensuring that your customers experience minimal delays.

Software-Defined Networking (SDN)

SDN separates the network’s control plane from the data plane, making it easier to manage and optimize traffic flow. With SDN, you can dynamically adjust the network paths to find the most efficient route for data. 

Imagine navigating through a city that constantly updates to provide the shortest route. That's SDN in action. In your corporate network, SDN can help you reroute traffic on the fly, ensuring that latency-sensitive applications always get the fastest path available.

Network virtualization, with these techniques and tools, allows you to sculpt your network infrastructure with precision. By managing traffic intelligently and scaling resources dynamically, you maintain the low latency environment crucial for your operations.

Technologies for high-speed data transfer

Fiber optics

These tiny strands of glass or plastic are the backbone of fast data transfer. They carry light signals at incredible speeds, reducing lag across vast distances. It's like having a direct highway for your data, with no speed limits. 

Fiber optics ensure that when you are on a video call with a client overseas, the conversation flows as smoothly as if they were in the next room.

Edge computing

This is all about processing data closer to where it's generated, rather than sending it far away to a central data center. This proximity cuts down on travel time, making interactions faster. 

Content Delivery Networks (CDNs)

These networks distribute your content across multiple locations worldwide. When a customer clicks on your website, the CDN delivers data from the nearest server. It's like having a mini version of your site stationed closer to the user. 

This proximity means pages load in an instant. For an e-commerce platform, this ensures customers have a smooth shopping experience, with no frustrating delays.

Efficient protocols

Technologies like HTTP/2 and QUIC are designed to speed up internet traffic. They handle multiple requests in parallel, reducing waiting time. Imagine browsing an online catalog and having each image appear the moment you scroll. These protocols make every click feel instantaneous, which is crucial for keeping users engaged on our site.

Quality of Service (QoS) mechanisms

These prioritize critical data over less important traffic. In a finance department, QoS ensures that transaction data zips through the network without delays. It's like giving priority boarding to time-sensitive information. This efficiency helps you to make fast, informed decisions that impact your bottom line.

Best practices for configuring networks to maximize data transfer speeds and minimize latency

Build your network on the right infrastructure.

Ensuring your network is built on a solid foundation of high-speed technologies, like fiber optics is essential for maximizing data transfer speeds and reducing latency. 

Consider investing in an optic fiber network when setting up a new office or upgrading existing facilities. This investment pays off during video conferences, where clear, immediate communication is crucial.

Make smart use of Content Delivery Networks (CDNs)

Using CDNs can significantly boost your website performance. With CDNs, you cache content at multiple locations worldwide, bringing data closer to your users. 

When someone visits your e-commerce site, the page loads quickly, thanks to a nearby CDN server. This proximity reduces latency and keeps customer engagement high. It’s like having a local checkout counter ready and waiting, regardless of where the customer is.
