How Polar‑TCP Breaks Kernel Network Bottlenecks for Cloud‑Native High‑Performance Services

This article explains how traditional kernel network stacks struggle with high‑concurrency, low‑latency cloud data‑center workloads and introduces Baidu Intelligent Cloud’s Polar solution—Polar‑TCP and Polar‑RDMA—which combine user‑space DPDK drivers, a lightweight TCP stack, and an industrial RPC framework to achieve near‑RDMA performance while preserving compatibility with existing TCP ecosystems.
