Chapter: Network Troubleshooting
Network performance issues can arise from various factors, including hardware limitations, configuration errors, or environmental interference. Below is a detailed explanation of common network performance problems and how to troubleshoot them effectively.
1. Congestion/Contention
Network congestion occurs when too many devices or users compete for limited network resources, leading to slow performance, high latency, and dropped connections. This is common in enterprise networks, service provider infrastructures, and wireless environments.
1. Problem: Network Congestion and Contention
- What It Means:
Congestion occurs when network bandwidth is insufficient to handle current traffic levels. Contention happens when multiple users or devices compete for the same network resources, leading to performance degradation.
