The present invention proposes a method to filter electronic messages in a message processing system, this message processing system comprising a temporary memory for storing the received messages intended to users, a first database dedicated to a specific ...
This paper addresses the problem of optimizing the playback delay experienced by a population of heterogeneous clients, in video streaming applications. We consider a typical broadcast scenario, where clients subscribe to different portions of a scalable v ...
We present a joint PHY/MAC architecture (DCC-MAC) for 802.15.4a-like networks based on PPM-UWB. Unlike traditional approaches it fully utilizes the specific nature of UWB to achieve high rates at low protocol complexity. It is the first MAC protocol that a ...
We consider cluster-based network servers in which a front-end directs incoming requests to one of a number of back-ends. Specifically, we consider content-based request distribution: the front-end uses the content requested, in addition to information abo ...
In a transactional system, an atomic commitment protocol ensures that for any transaction, all data managers agree on the same outcome: commit or abort. A non-blocking atomic commitment protocol enables an outcome to be decided at every correct data manage ...
Distributed shared memory 8DSM) is an abstraction of shared memory on a distributed memory machine. Hardware DSM systems support this abstraction at the architecture level; software DSM systems support the abstraction within the runtime system. One of the ...
This paper studies the performance of single-user workstations that access files remotely over a local area network. From the environmental, economic, and administrative points of view, workstations that are diskless or that have limited secondary storage ...
The authors investigate the impact of different implementations of an end-to-end transport service on the performance of high-volume data transfers in a local-area network. Of particular interest is the impact of using a connection-oriented logical-link co ...
The performance of the networking stack in an operating system depends on the overhead incurred by two of its components: the per-byte overhead incurred in data-touching operations, and the per-packet overhead of protocol processing and other operating sys ...
