Managing Metadata for Distributed Information Servers
In this paper we present the design and implementation of a distributed index architecture to facilitate metadata discovery on large networks. Many current information discovery systems use crawlers to search the Internet, constructing metadata from the data they nd. Instead, we propose a general distributed index architecture that uses descriptive hierarchies to organize metadata and route met...
متن کاملContent Routing for Distributed Information Servers
We describe a system that provides query based associative access to the contents of distributed information servers. In typical distributed information systems there are so many objects that underconstrained queries can produce large result sets and extraordinary processing costs. To deal with this scaling problem we use content labels to permit users to learn about available resources and to ...
متن کاملDistributed Cooperative Web Servers
Traditional techniques for a distributed web server design rely on manipulation of central resources, such as routers or DNS services, to distribute requests designated for a single IP address to multiple web servers. The goal of the Distributed Cooperative Web Server (DCWS) system development is to explore application-level techniques for distributing web content. We achieve this by dynamicall...
متن کاملDistributed Visibility Servers
This thesis describes techniques for computing conservative visibility exploiting viewpoint prediction, spatial coherence and remote visibility servers to increase the rendering performance of a walkthrough client. Identifying visible (or partially visible) geometry from an instantaneous viewpoint of a 3-D computer graphics model in real-time is an important problem in interactive computer grap...
متن کاملAge of Information in a Network of Preemptive Servers
A source submits status updates to a network for delivery to a destination monitor. Updates follow a route through a series of network nodes. Each node is a last-come-first-served queue supporting preemption in service. We characterize the average age of information at the input and output of each node in the route induced by the updates passing through. For Poisson arrivals to a line network o...
