The Internet backbone of many corporations carries two kinds of traffic: urgent and delayable. Shifting some traffic from peak periods to valleys reduces capacity requirements. We consider the case of managing the delayable traffic by an admission control (AC) system. AC gets link utilization feedback every τ seconds. Delayable opt-in sources obtain permission from AC to transmit for up to τ se...

This paper introduces the Furthest Hyperplane Problem (FHP), which is an unsupervised counterpart of Support Vector Machines. Given a set of n points in R, the objective is to produce the hyperplane (passing through the origin) which maximizes the separation margin, that is, the minimal distance between the hyperplane and any input point. To the best of our knowledge, this is the first paper ac...

Such categories offer a standardized and universal way for referring to or describing the nature of real world objects, activities, documents and so on, and may be used (we suggest) to semantically characterize the content of documents. WWW indices,...
