The overlay approach has been widely used by many service providers for Traffic Engineering (TE) in large Internet backbones. In the overlay approach, logical connections are set up between edge nodes to form a full mesh virtual network on top of the physical topology. IP routing is then run over the virtual network. Traffic engineering objectives are achieved through carefully routing logical ...

Anomaly detection is a widely explored domain in machine learning. Many models are proposed the literature, and compared through different metrics measured on various datasets. The most popular used to compare performances F1-score, AUC AVPR. In this paper, we show that F1-score AVPR highly sensitive contamination rate. One consequence it possible artificially increase their values by modifying...

A true Video-on-Demand (VOD) system provides the ultimate flexibility in video services by allowing users to select any video programs, at any time, and to perform any VCR-like user interactions. To allow true VOD, one approach is to have a dedicated video stream for each customer. This is expensive, especially when multiple identical video streams are sent to multiple customers accessing the s...

The recently published Committee for Medicinal Products for Human Use reflection paper on flexible designs highlights a controversial issue regarding the interpretation of adaptive trials. The guideline suggests that a test for heterogeneity should be preplanned and if treatment effect estimates differ significantly between design stages then data collected before and after the interim analysis...

This paper investigates explicit multiflow rate control for common forms of ensemble communication. We address rate control in the context of the Anypoint, a communication model that combines strong transport-layer guarantees with the flexibility of Anycast-style indirection. For example, Anypoint supports cluster-based services where extensible routers at the network edge route inbound request...

In recent times, a necessity has been raised in order to distribute computing applications often across grids. These applications are dependent on the services like data transfer or data portal services as well as submission of jobs. Security is of utmost importance in grid computing applications as grid resources are heterogeneous, dynamic, and multi-domain. Authentication remains as the signi...
