Recently we are in the middle of structural changes toward software-defined ICT infrastructure, which attempts to transform the existing silo-based infrastructure into futuristic composable one by integrating [...]

Netflix, YouTube, and the like, are now the dominant sources of traffic on the Internet. Recent studies observe that competing adaptive video streams generate flows [...]

We have examined maximum vertex coloring of random geometric graphs, in an arbitrary but fixed dimension, with a constant number of colors, in a recent [...]

The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. Uses [...]

We consider a scenario where an Internet Service Provider (ISP) serves users that choose digital content among M Content Providers (CP). In the status quo, [...]

Bootstrap percolation is a well-known activation process in a graph,in which a node becomes active when it has at least $r$ active neighbors.Such process, originally [...]

Abstract: Many of the most costly security compromises that enterprises suffer manifest as tiny trickles of behavior hidden within an ocean of other site activity. [...]

We consider a network of multi-server queues wherein each job can be processed in parallel by any subset of servers within a pre-defined set that [...]

Use of anycast IP addresses has increased in the last few years: once relegated to DNS root and top-level domain servers, anycast is now commonly [...]

Abstract: In the “big data” era, data is often dirty in nature because of several reasons, such as typos, missing values, and duplicates. The intrinsic [...]
