The Active Streams approach to adaptive distributed systems

The explosive growth of the Internet, with the emergence of new networking technologies and the increasing number of network-capable end devices, is paving the way for a number of novel distributed applications and services. Cooperative distributed systems have become a common computing model, and pervasive computing has caught the interest of academia and industry. To support future network applications, we believe that new services need to be customizable, applications need to be dynamically extensible, and both applications and services should be able to adapt to variations in resource availability and demand. propose Active Streams (F.E. Bustamante and K. Schwan, 1999), a middleware approach and its associated framework for building distributed applications and services that exhibit these characteristics.
