The Valiant Load-Balancing (VLB) design has been proposed for a backbone network architecture that can efficiently provide predictable performance under changing traffic matrices [1]. In this paper we show that the VLB network has optimal performance when nodes can fail, in the sense that it can support the maximal homogeneous flow for any number of node failures. We generalize the VLB design to...

From an existing lexical database (such asWordNet), Castanet carves out a structure that reflects the contents of the target information collection; moderate manual...

We are now starting to see true-facilities-based competition for wired voice and video services for the first time in many markets as the telephone and cable operators offer directly competing services.

While RFID technology has existed for decades, these new applications carry with them substantial new privacy and security risks for individuals. These risks arise due to a combination of aspects...

Widespread adoption of uniform standards is essential to the smooth operation of our modern global economy. When private or-ganizations develop such standards, copyright protection of those stan-dards often creates a conºict between private intellectual property rights and society's need for standards. This conºict is especially appar-ent when a local or state government adopts a privately...

In improving the transparency of these disclosures, we allow policymakers, analysts, investors and the general public to analyse these relationships at both the firm level and the industry level. Using...
