The explosive growth of Internet-based applications and the proliferation of networking technologies have transformed not only the computer science and engineering fields but also has affected the areas of computational science and commercial Internet applications. This has provided researchers with an opportunity to explore new Internet-oriented software technologies designed to expand research and application opportunities in multimedia, commerce, and the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - provide increased programmability to bring new services to Internet-based applications. The chapters in this volume are based on presentations at the Second Annual Workshop on Active Middleware Services. The volume draws on research results in active networks, mobile and intelligent agents, software tools for high-performance distributed computing, network operating systems, and application programming models and environments.The text should be appropriate for engineers and researchers in the areas of network centric computing and distributed information systems, as well as for application and tool developers and users of information systems.

The papers in this volume were presented at the Second Annual Work­ shop on Active Middleware Services and were selected for inclusion here by the Editors. The AMS workshop was organized with support from both the National Science Foundation and the CAT center at the Uni­ versity of Arizona, and was held in Pittsburgh, Pennsylvania, on August 1, 2000, in conjunction with the 9th IEEE International Symposium on High Performance Distributed Computing (HPDC-9). The explosive growth of Internet-based applications and the prolifer­ ation of networking technologies has been transforming most areas of computer science and engineering as well as computational science and commercial application areas. This opens an outstanding opportunity to explore new, Internet-oriented software technologies that will open new research and application opportunities not only for the multimedia and commercial world, but also for the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - allow increased programmability to enable bring­ ing new services to Internet based applications. The AMS workshop presented research results and working papers in the areas of active net­ works, mobile and intelligent agents, software tools for high performance distributed computing, network operating systems, and application pro­ gramming models and environments. The success of an endeavor such as this depends on the contributions of many individuals. We would like to thank Dr. Frederica Darema and the NSF for sponsoring the workshop.

The term "grid computing" is based on an analogy with the electrical power grid: computing capabilities should be ubiquitous and easy to use. While the development of what we now call grid computing is, in many ways, part of a natural progression of work done in the last decade, what's special about it is that all of its enabling technologies are converging at once: (1) a widely - ployed, network infrastructure will connect virtually every device in the world, (2) an interface technology is widely understood and embraced by virtually every segment of science, technology, commerce, and society, and (3) there is a wi- spread, and growing, understanding of the properties, capabilities, and services that are necessary and possible to utilize this infrastructure. Information services and resource brokers will allow the dynamic sharing of resources for applications large and small and enable virtual organizations. These properties, capabilities, and services will be used in different contexts to enable different styles of c- puting such as Internet computing and Peer-to-Peer computing. To facilitate the adoption of standard practices, the Global Grid Forum (www. gridforum. org) was formed to identify common requirements and push for eventual standardization. The phenomenal growth of grid computing and related topics has created the need for this workshop as a venue to present the latest research. This year's workshop builds on the success of last year's.
