    Our current understanding of Web structure is based on large graphs created by centralized crawlers and indexers. They obtain data almost exclusively from the so-called surface Web, which consists, loosely speaking, of interlinked HTML pages. The deep Web, by contrast, is information that is reachable over the Web, but that resides in databases; it is dynamically available in response to queries, ... View full abstract»

    The popularity of large-scale Internet infrastructure services such as AOL, Google, and Hotmail has grown enormously. The scalability and availability requirements of these services have led to system architectures that diverge significantly from those of traditional systems like desktops, enterprise servers, or databases. Given the need for thousands of nodes, cost necessitates the use of inexpen... View full abstract»

    Workspaces is a Web-based WFMS developed at the Technical University of Berlin that attempts to deal with various shortcomings of Web-based workflow management systems by employing XML. The proposed architecture combines concepts from workflow management and coordination technology and uses XML for representation and the Extensible Stylesheet Language (XSL) for processing. The author examines the ... View full abstract»

    When we launched the Akamai system in early 1999, it initially delivered only Web objects (images and documents). It has since evolved to distribute dynamically generated pages and even applications to the network's edge, providing customers with on-demand bandwidth and computing capacity. This reduces content providers' infrastructure requirements, and lets them deploy or expand services more qui... View full abstract»

  • Weaving a computing fabric

    As sources of information relevant to a particular domain proliferate, we need a methodology for locating, aggregating, relating, fusing, reconciling, and presenting information to users. Interoperability thus must occur not only among the information, but also among the different software applications that process it. Given the large number of potential sources and applications, interoperability ... View full abstract»

  • Trade-offs in designing Web clusters

    High-volume Web sites often use clusters of servers to support their architectures. A load balancer in front of such clusters directs requests to the various servers in a way that equalizes, as much as possible, the load placed on each. There are two basic approaches to scaling Web clusters: adding more servers of the same type (scaling out, or horizontally) or upgrading the capacity of the server... View full abstract»

    Device manufacturers, users, and authors have differing needs and expectations when it comes to Web content. Web software and hardware manufacturers naturally try to differentiate their products by supporting a special combination of capabilities, but few can expect Web authors to create content for their product alone. Users, however, do expect to access the same content from any device with simi... View full abstract»

    We describe our approach to secure authentication and authorization for extended enterprises, which combines distributed role-based access control (RBAC), a public key infrastructure (PKI), and a privilege management infrastructure (PMI). We have implemented a J2EE-based prototype system, DRBAC-EE, which shows the feasibility of our approach. View full abstract»

  • Wired-wireless integration

    Publication Year: 2002

    Within a few years, most wireless devices will interconnect across networks to allow information access from anywhere, anytime. This evolution motivates developers to migrate technologies originally developed for PCs to wireless devices. Supporting this effort, however, requires new software -particularly middleware -to power small devices that connect over slow, sometimes unreliable networks. How... View full abstract»

    Any large organizations that first came online in the late 1990s are now facing the decision whether to upgrade their Web systems or to start anew. Given the speed with which new technologies are introduced in the Web environment, system deployment life cycles have shrunk significantly-but so have system life spans. After only a few years, an organization's Internet infrastructure is likely to nee... View full abstract»

  • Middleware "dark matter"

    Clay Shirky describes PCs as the "dark matter of the Internet" because a lot of them are connected, but they're barely detectable. We can apply a similar analogy to middleware because the "mass" of the middleware universe is much greater than the systems - such as message-oriented middleware (MOM), enterprise application integration (EAI), and application servers based on Corba or J2EE - that we u...

    As a middle-tier, server-side caching engine, the dynamic content accelerator reduces dynamic page-generation processing delays by caching fragments of dynamically generated Web pages. This fragment-level solution, combined with intelligent cache management strategies, can significantly reduce the processing load on the Web application server, letting it handle higher user loads and thus significa...
