Project summary |
Our research is concerned with how to upgrade software in distributed systems: how to cause the code running in the system to change while the system continues to run.
Project description |
The research is concerned with very large robust systems that are intended to provide continuous service over a very long lifetime. Examples include a distributed object-oriented database system in which persistent objects are stored at thousands of geographically distributed servers; a system that speeds up delivery of rich media by pre-positioning content at thousands of geographically distributed caches; an embedded system in which sensors collect information that is combined and then used to control actuators; and a system providing archival file storage for millions of users. |
