Network optimization is the process of improving the performance and efficiency of a computer network. It involves analyzing network traffic, identifying bottlenecks, and implementing strategies to reduce latency, increase throughput, and ensure reliable data delivery. This practice is crucial for maintaining smooth operations, enhancing user experience, and supporting business objectives by ensuring resources are used effectively. For instance, implementing Quality of Service (QoS) policies prioritizes critical traffic like VoIP calls over less time-sensitive data, preventing call drops during peak usage. Network optimization is distinct from simple network monitoring, which primarily focuses on identifying issues rather than actively improving performance. Understanding network optimization is essential for roles covered in certifications like CompTIA Security+, CISSP, and CCSP.
