我们为存储，更新和提供移动物联网设备或对象的记录提供了一种新颖的IoT目录服务。 IoT目录服务旨在管理大量记录（约10亿）并支持快速查找（延迟小于10ms）。它通过动态分配虚拟化网络和计算资源来实现各种复制品（遵循移动物联网设备或应用程序客户端的移动）中记录的主动缓存，以使查找延迟始终保持较低。每当由于移动性而更改记录时，都会跟踪缓存复制品（几秒钟的延迟）。我们已经初步实现了目录服务系统，并在查找和更新潜伏期方面研究了其性能。
We propose a novel IoT directory service for storing, updating, and providing records of mobile IoT devices or objects. The IoT directory service is designed to manage a massive number of records (about one billion) and support fast lookup (latency of less than 10ms). It performs proactive caching of the records in various replicas (following the movement of mobile IoT devices or application clients) by dynamically assigning virtualized network and computing resources so that the lookup latency always remains low. The cache replicas are tracked to update them globally (latency of few seconds) whenever a record changes due to mobility. We have preliminarily implemented the directory service system and studied its performance in terms of lookup and update latencies.
