**分布式架构是鸿蒙四大特性之一，也是首次用于终端OS。鸿蒙分布式架构包含了任务调度、数据管理、硬件能力虚拟化、分布式软总线四大能力，它将底层实现与应用开发剥离开来，让开发者以更低难度开发跨终端分布式应用。**

**极简协议是华为分布式软总线的核心技术。它和TCP/IP不同，把OSI参考模型中的表示层、会话层、传输层、网络层协议栈精简为一层，这就让优化首部信息以提高有效载荷，精简封装和拆包步骤成为了可能。根据官方数据，分布式软总线实现了小于20ms的低时延、1.2Gbps的高吞吐量和25%的扛丢包率。**这为大幅提高硬件共享、数据互通水平提供了保证。换句话说，智能穿戴、IoT、车机等算力较低、存储较小的设备将能共享手机的算力和存储。
