摘　　要：为保证云计算服务的持续运行,云计算平台需要支持动态更新技术。针对过去主流的动态更新技术如滚动更新存在多版本混合的问题,文中提出了基于网络动态调整的优化方案。通过将更新后的服务实例与待更新的服务实例在网络上隔离,使旧版本服务无法访问有兼容性问题的新版本服务,从而解决了多版本混合问题,并且在Docker Swarm的基础上设计并实现了原型系统,通过实验验证了该方案的有效性。With the development of cloud computing services,more and more applications through the clo-ud platform to provide their services. In order to ensure the continuous operation of these services,cloud com-puting platform needs to support dynamic updating technology. In the past,popular dynamic updating technolog such as rolling updating has mixed version problem. in order to solve this problem,we have proposed a dyn-amically adjusting network strategy. The mixed version problem is solved by isolating the updated service insta-nce from the service instance to be updated on the network,so that the old version service can not access the new version service with the compatibility problem. We design and implement the prototype system on the ba-sis of Docker Swarm,and verify the effectiveness of the scheme through experiments.
