How User‑Space MPTCP with DPDK Doubles Throughput in Data Centers

This article details the design, implementation, and performance evaluation of a user‑space MPTCP stack built on DPDK, showing how a layered, zero‑copy architecture and same‑core lock‑free forwarding can boost data‑center throughput by up to 100% while reducing latency by about 10%, all while remaining compatible with existing TCP applications.

How NUMA‑Aware MPTCP Flow Selection Boosts Throughput and Cuts Latency

At Netdev 0x19, ByteDance's STE team presented two talks—one on a NUMA‑locality‑aware MPTCP flow‑selection strategy that can raise throughput by up to 30% and lower tail latency by 6%, and another on a DPDK‑based user‑space MPTCP stack that reduces latency by nearly 10% and more than doubles throughput—showcasing practical performance gains for data‑center networking.

Research on WiFi-Cellular Network Seamless Handover Technology for Mobile Devices

The article examines the delay‑inducing challenges of Wi‑Fi‑to‑cellular handover on mobile devices and proposes three complementary techniques—dynamic link evaluation, QUIC‑based connection migration, and multipath TCP—to reduce detection, link‑setup, and TCP‑reconstruction times, while weighing power, cost, and future AI‑driven trajectory prediction.
