Networks manage bandwidth allocation by employing several techniques, such as traffic shaping, quality of service (QoS)load balancing. Traffic shaping prioritizes certain types of data for smoother performance, while QoS assigns different levels of priority to services based on their requirements. Load balancing distributes network traffic evenly across multiple servers to prevent any single server from becoming a bottleneck. Network monitoring tools also analyze usage patterns, helping administrators optimize bandwidth and ensure fair access for users. This proactive management is essential for maintaining a positive user experience and efficient network performance.
