Achieving per-flow Queueing Performance without a per-flow Queue

Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much b...

Dossier " Ict and Heritage " Challenges for Ict/uct Applications in Cultural Heritage* Paraules Clau

While a precise forecast for the next decades is clearly impossible, some major challenges that need to be addressed in the next 10-20 years can be identified. Technologically there will be a shift from Information and Communication Technologies (ICT) to Universal Convergence Technologies (UCT). In the cultural realm, these challenges include problems of repositories, the changing scope of cult...

A Fifty Gigabit Per Second IP Router

Aggressive research on gigabit per second networks has led to dramatic improvements in network transmission speeds. One result of these improvements has been to put pressure on router technology to keep pace. This paper describes a router, nearly completed, which is more than fast enough to keep up with the latest transmission technologies. The router has a backplane speed of 50 Gb/s and can fo...

Geomarketing on a Pay-per-Use Basis

Geomarketing applications use a large amount of geographic and demographic data. Due to the extremely high costs for this data geomarketing is only feasible for large companies that can afford such data sets, or for companies offering specialized geomarketing services to a number of clients. This paper describes a possible solution for small and medium enterprises to do geomarketing at reasonab...
