In the rapidly evolving landscape of cloud computing and microservices architecture, efficiently and securely managing communication between services has become a critical challenge. Traditional methods of network traffic authentication often become a performance bottleneck, especially when handling large-scale data flows. This session introduces an innovative solution — leveraging Linux kernel technology XDP (eXpress Data Path) to achieve efficient traffic authentication for service-to-service communications.
We will delve into how to use XDP for rapid filtering and processing of packets before they enter the system's protocol stack, significantly reducing latency and enhancing overall system throughput. Additionally, we will share practical application experiences from projects such as Kmesh, including but not limited to performance tuning, security considerations, and integration with other network security strategies.
Operating system engineer of Huawei Technologies Co., Ltd., core member of Kmesh, contributor of libxdp. Enthusiastic about cloud native technology and eBPF-based high performance network.
