Packet Scheduling
Packet scheduling is a networking concept that determines the order and timing of packet transmission from a queue or buffer in network devices like routers and switches. It involves algorithms that manage bandwidth allocation, prioritize traffic, and ensure quality of service (QoS) by controlling how packets are forwarded to output links. This process is critical for optimizing network performance, reducing latency, and preventing congestion in data communication systems.
Developers should learn packet scheduling when working on network-intensive applications, such as video streaming, online gaming, or VoIP services, where low latency and reliable throughput are essential. It is crucial for implementing QoS in routers, switches, and software-defined networking (SDN) to manage traffic efficiently, prioritize critical data, and ensure fair resource allocation among multiple users or applications.
