Network latency refers to the delay before data transfer begins, measured in milliseconds (ms). It is a critical factor in determining the performance of online services and applications. Below are key points to grasp:
Common Causes of Latency ⚠️
- Physical Distance: Data travels slower over longer distances due to the speed of light limits in fiber optics.
- Network Congestion: High traffic volumes on routers or internet service providers (ISPs) can slow data transmission.
- Device Processing: Bottlenecks in hardware (e.g., outdated routers, slow servers) increase latency.
- Protocol Overhead: Complex protocols like TLS/SSL add processing time.
Impact on User Experience ⚡
- Streaming Services: High latency causes buffering (e.g., 📺 video pauses).
- Online Gaming: Delays lead to lag (e.g., 🎮 actions not syncing in real-time).
- Real-Time Communication: Audio/video calls suffer from choppy performance (e.g., 🗣️ voice delays).
Solutions to Reduce Latency 🛠️
- Optimize Routing Paths
Use tools like traceroute to identify bottlenecks. - Upgrade Infrastructure
Switch to faster internet plans or hardware (e.g., 5G, SSDs). - Content Delivery Networks (CDNs)
Distribute content closer to users via CDN services. - Minimize Protocol Complexity
Reduce encryption layers or use lightweight protocols.
