We consider models of content delivery networks in which the servers are constrained by two main resources: memory and bandwidth.

We consider a system with two exponential servers (with unequal rates), an infinite buffer, and a Poisson arrival process.

We consider a queueing system with two servers and an infinite buffer. Service times are exponentially distributed and customers arrive in a Poisson process.

Distributed computing networks, tasked with both packet transmission and processing, require the joint optimization of communication and computation resources.

We consider a mobile connected to a base station, and study how to optimally schedule shutting off its transceiver. First, we study the model from optimal control perspective.

High availability of containerized applications requires to perform robust storage of applications' state.

Augmented information (AgI) services allow users to consume information that results from the execution of a chain of service functions that process source information to create real-time augmented

Given a set of points P Ì Rd and value e>0, an e-core-set SÌP has the property that the smallest ball containing S is within e of the smallest ball containing P.

SONET/SDH rings appear to be well-positioned to serve as the transport network for the next generation of voice and data networks.

This paper identifies the important differences between a traditional VPN and the mobile VPN and proposes a hierarchical network architecture to efficiently realize network-based mobile VPNs.
