📊 Network Performance Issues Network performance is essential to the efficiency and reliability of communication systems. The following are common performance issues that affect network communication: Latency: The delay in transmitting data from source to destination. Throughput: The rate at which data is successfully transferred from sender to receiver. Packet Loss: Loss of data packets during transmission, causing retransmissions. Jitter: Variations in the delay of data packets, leading to inconsistent network performance. ⚡ Fast Segment Processing To improve network performance, fast segment processing is critical. Techniques include: ...
