We share insights on storage, computing, networking and explore leading industry technologies together.
In September 2024, TencentOS sent two kernel engineers to Vienna to attend the Linux Plumbers Conference and the Linux Kernel Developers' Netconf, where they presented cutting‑edge research on network diagnostics, SWAP allocation, and memory management, fostering collaboration with leading open‑source contributors.
The article introduces X‑Stor, a cloud‑native NoSQL database service that supports multiple data models and process‑level multi‑tenant isolation, describes its plugin‑based architecture and Request Unit metric, and presents experimental results showing superior performance, effective tenant isolation, and load‑balancing benefits compared with traditional single‑model NoSQL systems.
The article explains how OpenCloudOS, a fully self‑developed Linux operating system, attains industry‑leading six‑nine (99.9999%) availability by strengthening kernel quality, implementing comprehensive CI testing, managing vendor drivers, handling upstream bugs, and deploying automated crash analysis and rapid recovery mechanisms.
The article introduces Metis, an AI‑based solution that replaces traditional regular‑expression matching for network traffic inspection, offering faster, more accurate detection, a compact model deployable on resource‑constrained P4 switches, and significant performance and cost benefits for cloud gateway security.
The article introduces OpenCloudOS’s cloud‑native initiatives—including a mixed‑workload CPU QoS scheduler, the RUE resource‑utilization enhancement, the eBPF‑based nettrace network‑diagnosis tool, and the TCase/TSuite testing platform—highlighting how these innovations improve CPU utilization, cut costs, and ensure high‑quality releases.
This article explains the fundamentals of 3D video imaging, compares traditional 3D encoding methods with the MV-HEVC standard, and details how Tencent's V265 encoder implements MV-HEVC to achieve significant bitrate savings for Apple Vision Pro and other multiview applications.
This article details a systematic investigation and multi‑stage optimization of TencentOS network latency, uncovering kernel soft‑interrupt bottlenecks, proposing and upstreaming patches to net_rx_action, RPS handling, and ksoftirqd scheduling, ultimately reducing handshake failures by over 80% while sharing practical insights for Linux kernel developers.
The article presents oc-ops, a unified command‑line toolset for OpenCloudOS that streamlines Linux kernel management by offering standardized syntax, sub‑commands for memory cost analysis, I/O latency monitoring, and IRQ latency detection, along with detailed usage parameters and best‑practice recommendations.
This article presents a comprehensive overview of TencentOS’s evolution and its data‑center resource and energy management techniques, covering the OS’s mission for economic and green operation, resource utilization metrics (UTE, QOS, ROI), current management technologies, energy‑aware scheduling, performance results, and future development directions.
Tencent's TXAV1 encoder, a self‑developed AV1 video codec, combines advanced compression‑rate improvements, engineering acceleration, and extensive cloud deployment, achieving up to 78‑334% speedup with minimal quality loss, and includes novel pre‑analysis models, adaptive quantization, and multi‑threading strategies for both video and image applications.
