Since the mid 1990s, network and systems management has steadily evolved from a centralized paradigm, where all the management processing takes place in a single management station, to distributed paradigms, where management is distributed over a potential ...
We consider the transmission of variable bit rate (VBR) video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming wit ...
We propose a novel approach to Quality of Service, intended for IP over SONET (or IP over WDM) networks, that offers end-users the choice between two service classes defined according to their level of transmission protection. The first service class (call ...
The management of IP networks is currently based on the SNMP protocol, and the use of expensive network management platforms designed according to the manager/agent paradigm of the SNMP framework. It uses two different schemes to transfer management data: ...
An atomic-scale description is provided for the long-range oxygen migration through the disordered SiO2 oxide during silicon oxidation. First-principles calculations, classical molecular dynamics, and Monte Carlo simulations are used in sequence to span th ...
We consider a network implementing scheduling per aggregate flow. We show that the derivation of bounds that was published in [1] is false. We give a worst case bound which is valid for any network topology, given the maximum hop count for every flow and t ...
Routing as well as the management of communication networks that support hybrid types of communications requiring quality of service is a hard problem. We present here a framework1 that decomposes the network into a hierarchy of abstract views of the netwo ...
A simple and efficient technique for the fabrication of buried microfluidic channels is presented. Microchannels made using a contribution of thick liquid and laminated photopolymers are used for the realization of smart microchips for culture, stimulation ...
Mapping algorithm for protecting a network using a Wavelength Division Multiplexing (WDM) infrastructure against component or link failures while respecting capacity constraints. ...
Current charging mechanisms in the Internet are restricted mainly to volume and time of the day. We propose a mechanism which allows to use additional information for charging in the edges and core of the network. Links or network clouds will have weights ...
