Many BGP route leaks reported by automated detection systems are actually brief, low-impact artifacts of normal BGP convergence. Long round‑trip times have serious consequences for protocols like TCP, which rely on a steady stream of acknowledgements (ACKs) to manage sending rates, estimate delay, and trigger retransmissions. As datacenter networks evolve toward ultra-high-speed links, the energy footprint of host-side packet processing grows increasingly significant. The old perception of sa...
