The Accurate Hose Model for VPN Provisioning
This work considers the problem of VPN provisioning, focusing on the process of dimensioning the links belonging to the route that connects VPN endpoints, according to the specified traffic demands. To accomplish this, we propose a new model, the Accurate Hose, which can take into consideration a complete or partial traffic matrix and supports group based bandwidth requirements, while maintaini...
متن کاملNew Bounds for the Garden-Hose Model
We show new results about the garden-hose model. Our main results include improved lower bounds based on non-deterministic communication complexity (leading to the previously unknown Θ(n) bounds for Inner Product mod 2 and Disjointness), as well as an O(n · log n) upper bound for the Distributed Majority function (previously conjectured to have quadratic complexity). We show an efficient simula...
متن کاملAlgorithms for Provisioning Virtual Private Networks in the Hose Model
Virtual Private Networks (VPNs) provide customers with predictable and secure network connections over a shared network. The recently proposed hose model for VPNs allows for greater flexibility since it permits traffic to and from a hose endpoint to be arbitrarily distributed to other endpoints. In this paper, we develop novel algorithms for provisioning VPNs in the hose model. We connect VPN e...
متن کاملMTRA: An on-line hose-model VPN provisioning algorithm
Virtual private networks (VPNs) provide customers with a secure and manageable communication environment. The allocation of bandwidth for VPNs to meet the requirements specified by customers is now one of the most important research issues in the field of traffic engineering. A VPN resource-provisioning model called hose-model was developed to provide customers with a flexible and convenient wa...
متن کاملTest of the Electron Hose Instability in the E157 Experiment*
The E157 experiment is designed to demonstrate highgradient Plasma Wake Field Acceleration over a significant length. It has been suggested that the electron hose instability of the drive beam will degrade the performance of this experiment because the hosing tailelectrons will not fully sample the highest acceleration field. In this paper a parasitic experiment designed to test the extent of t...
