Survey of Supporting System for Dynamically Updating Distributed System
分布式动态更新支持系统：研究综述

Many critical application systems need constant evolving for correcting bugs, extending functions or improve system's performance. However, they need to have abilities to afford service when they are being updated, i. e, their being updated have to be implemented dynamically. To transparently support distributed systems' dynamic updating, the following work need to be done with: automatically propagate updating messages; change nodes' components' call from old to new interfaces; test systems' validity and consistency after updating; do with the tolerance if updated sys- tem is invalid or inconsistent; support interaction between multi-version components; do with messages after updating which arrived at updating. This paper presents general introduction about requirements, functions, key research prob- lems, related work and future work for building supporting-system for dynamically updating distributed system.
