- May 5, 2026 Early RTCP Feedback: Negative Acknowledgements, Picture Loss, and Transport Congestion How the feedback profiles let a receiver report loss in milliseconds instead of seconds, what each message type asks for, and the timing rules that keep them from flooding a session. internet protocols
- Feb 28, 2026 Chunked Transfer and Retransmission in Firmware Delivery How an image crosses a slow or unreliable link in numbered chunks, why the window size is bounded by the receiver buffer, and where the retry logic belongs. embedded systems
- Dec 27, 2025 Loss Detection Without Retransmitted Packets How QUIC infers loss from packet-number gaps and time thresholds, why frames rather than packets are retransmitted, and how probe timeouts keep a connection from stalling. internet protocols
- Jun 5, 2025 SACK Blocks and the Retransmission Queue How selective acknowledgement turns a cumulative ACK into a map of received ranges, why the sender keeps a scoreboard, and what the option length limit costs. networking
- Jul 6, 2024 Retransmission Timeout Estimation and Karn's Algorithm Why the retransmission timer is computed from a smoothed round-trip estimate plus a variance term, and why timing a retransmitted segment corrupts the estimate. networking
- Jan 23, 2023 Retransmission and the Duplicate Request Cache A lost reply is indistinguishable from a lost request, so a client resends and a server must decide whether the operation already ran. The reply cache is the mechanism that turns at-least-once delivery into at-most-once execution. filesystems
