Several new architectures have been developed for supporting multimedia applications
such as digital video and audio. However, quality-of-service (QoS) routing is an important …

We propose a new design for highly concurrent Internet services, which we call the staged
event-driven architecture (SEDA). SEDA is intended to support massive concurrency …

The memory coherence problem in designing and implementing a shared virtual memory on
loosely coupled multiprocessors is studied in depth. Two classes of algorithms, centralized …

Scalable management and self-organizational capabilities are emerging as central
requirements for a generation of large-scale, highly dynamic, distributed applications. We …

Over the years, the web has evolved from simple text content from one server to a complex
ecosystem with different types of content from servers spread across several administrative …

Attempts to generalize the Internet's point-to-point communication abstraction to provide
services like multicast, anycast, and mobility have faced challenging technical problems and …

This dissertation presents a new approach to managing failures and evolution in large,
complex distributed systems using runtime paths. We use the paths that requests follow as …

Distributed systems are easier to build than ever with the emergence of new, data-centric
abstractions for storing and computing over massive datasets. However, similar abstractions …

Pervasive computing environments pose unique service discovery challenges. We have
developed a taxonomy of existing protocols as a basis for analyzing their approaches and …

The Context Toolkit (Dey, Abowd, and Salber, 2001 [this special issue]) is only one of many
possible architectures for supporting context-aware applications. In this essay, we look at the …
