For an important class of safety- and mission-critical software systems, such as air traffic control, telephone switching, and high availability public information systems, shutting down and restarting the system for upgrades incurs unacceptable delays, increased cost, and risk. Support for runtime modification is a key aspect of these systems. Dynamic software architectures represent one encouraging approach to mitigating these difficulties.

These pages attempt to organize and coalesce the on-going work in the field of dynamic software architectures. Additions, errors, comments, etc. should be directed to peymano at
