Packet loss is likely a familiar issue if you\u2019ve managed networks susceptible to slower network speeds, degraded data quality, or increased latency. It directly impacts network operations and digital experiences, which is why we recommend that you take the time to understand and prevent it.<\/p>\n

At eG Innovations, we provide an end-to-end IT performance monitoring and optimization platform designed to help you manage packet loss and other IT performance issues. Join us as we discuss what causes packet loss, its effects, and practical solutions for mitigation. We\u2019ll also look into how our platform can help you detect and analyze packet loss to guarantee reliable IT performance. Let’s begin by explaining what network packet loss is and offer some real-world examples. <\/p>\n

<\/span>What Is Packet Loss?<\/span><\/h2>\n

Data sent over a network or between devices takes the form of packets, which are small chunks of a larger piece of information. However, packet loss occurs when these data packets don’t reach their intended destination. This can happen at any point along the data path, and the consequences can be dire.<\/p>\n

For instance, packet loss may slow down your application’s performance, leading to delays when transferring files, answering database queries, or providing cloud services. Similarly, it can cause issues like buffering and interruptions in playback for video streaming platforms, frustrating your users. In voice-over-IP (VoIP) calls, packet loss results in choppy audio, delays, or dropped calls. <\/p>\n

Even a small amount of packet loss can drastically affect network efficiency and application reliability, particularly for real-time applications like video conferencing or online gaming. That’s why your IT team must monitor and address it accordingly to minimize downtime, maintain service-level agreements (SLAs), and optimize workflows. <\/p>\n

<\/span>Causes of Packet Loss<\/span><\/h2>\n

\"\"
\nGrasping what causes packet loss is the secret to diagnosing and mitigating its impact on network performance. Below, we\u2019ll explore some of the most common reasons why data packets transmitted over a network may fail to reach their destination. <\/p>\n

Network Congestion<\/p>\n

Just like on roads, a lot of network traffic results in congestion. Network congestion typically occurs when the amount of data packets being sent over a network is too high for it to handle. Routers may drop some packets to relieve the network load and maintain performance. <\/p>\n

When is your network likely to be congested? During peak usage times, such as when streaming high-definition video and gaming online or when there’s a server overload. In the event of any of these cases, data delivery is delayed, and your users are likely to experience poor network quality. <\/p>\n

Hardware Failures<\/p>\n

Faulty hardware in your network devices, including routers, switches, and cables, can contribute to packet loss. Aging equipment, overheating components, or physical damage could cause these issues. Poor maintenance practices may also lead to malfunctioning network interface cards (NICs) and faulty ethernet cables that can cause intermittent connectivity, disrupt data flow, and lead to packet loss.<\/p>\n

Software Issues<\/p>\n

Software-related problems stemming from bugs, outdated programs, and misconfigurations in your network systems often lead to packet loss. For example, misconfigured firewalls may block or filter legitimate packets, disrupting data transmission. Similarly, outdated network firmware can fail to address bugs and recent security vulnerabilities, resulting in the loss of essential data packets. <\/p>\n

Wireless Interference<\/p>\n

Wireless networks are also susceptible to packet loss, which usually happens when the signal transmission of data packets is disrupted. This could be due to a signal overlap, where many wireless networks operate on the same channels, so data packets are distorted or lost.<\/p>\n

Moreover, interference on your wireless network can be caused by physical obstacles, such as walls and furniture. Electronic devices like microwaves also commonly produce radiofrequency signals that interfere with data transmission over a wireless network.<\/p>\n

Security Attacks<\/p>\n

Computer crimes, mainly Distributed Denial of Service (DDoS) attacks, can overwhelm your network with excessive traffic, causing packet loss. These criminal activities aim to disrupt network operations, mainly targeting high-profile servers. Often, they result in downtime, loss of sensitive data, and damage to network infrastructure. Detecting and mitigating their effects can be tricky without proactive monitoring and robust security protocols. <\/p>\n

<\/span>Effects of Packet Loss<\/span><\/h2>\n

Packet loss creates challenges that negatively impact IT performance and digital experiences. Its effects include the following:<\/p>\n
