iREX MPO : A Multi-Path Option for the iREX Inter-Domain QoS Policy Architecture

A. D. Yahaya, T. Suda
2008 2008 IEEE International Conference on Communications  
In iREX, each policy reservation is deployed on a single E2E ID path made up of the most "desirable" (i.e. cheapest and least congested) ISP resources.  ...  accommodate ISPs that prefer redundancy when deploying ID QoS policy, in this paper we introduce an extension to the iREX architecture that gives an originating ISP a multipath option (MPO) when deploying a reservation  ...  We define a link as congested when more than 50% of its bandwith is in use.  ...

Dynamic photonic lightpaths in the StarPlane network

Paola Grosso, Damien Marchal, Jason Maassen, Eric Bernier, Li Xu, Cees de Laat
2009 Future generations computer systems  
When an application needs to reconfigure the underlying network, it reserves a point to point link from DRAC using a web service interface.  ...  DRAC then computes the availability of the connection, determines the best route for the signal and requests the connection from CPL using the Domain Optical Controller.  ...

A Minimum Cut Interference-based Integrated RWA Algorithm for Multi-constrained Optical Transport Networks

Francesco Palmieri, Ugo Fiore, Sergio Ricciardi
2008 Journal of Network and Systems Management  
A WDM-based all-optical network consists of wavelength switching devices interconnected by point-to-point fiber links in an arbitrary mesh topology.  ...  Our work focuses on such dynamic online integrated RWA problem, where incoming connection requests are routed on the optical transport network using the current state of the network, such as link load  ...  Each new connection request can be routed over a direct lightpath modelled as a single cut-through edge in our multi-graph, or over a sequence of lightpaths (a multi-hop path at the IP level, where each  ...

Performance evaluation of a Linux DiffServ implementation

Günther Stattenberger, Torsten Braun, Matthias Scheidegger, Marcus Brunner, Heinrich J Stüttgen
2002 Computer Communications  
Resources are reserved for any flow aggregation e.g. for all flows between two subnets. These reservations are rather static since dynamic reservations for single connections do not scale.  ...  TCP The TCP tests were performed with a bandwith reservation of 5 MBit/s, too.  ...

A Distributed Scheme for Value-Based Bandwidth Reconfiguration [chapter]

Åke Arvidsson, Johannes Göbel, Anthony Krzesinski, Peter Taylor
2009 Lecture Notes in Computer Science  
AKE: Below I changed and added a few words to include the notation of a "bandwith broker".  ...  At specified time points, bandwidth can be allocated to those paths that (possibly temporarily) value it most highly.  ...  Nodes 1 and 2 are connected by a direct route r 1 of capacity C 1 which is provisioned by reserving capacity on the path L 1 = {ℓ 1 }.  ...

Optimizing Deadline-Driven Bulk Data Transfers in Overlay Networks

Andrei Agapi, Sebastien Soudan, Marcelo Pasin, Pascale Vicat-Blanc Primet, Thilo Kielmann
2009 2009 Proceedings of 18th International Conference on Computer Communications and Networks  
We formally define and address the associated problem, the Bulk Data Routing and Transfer(BDRT) and present a linear programming-based solution to it, optimal in both routing and time domains.  ...  Our optimization jointly addresses routing of transfers within the overlay and the time-domain scheduling of transfer bandwidths.  ...  BDRT is slower up to the point where K=70 (low connectivity), respectivelly K=50 (full mesh), at which point BDTS/* become comparable or slower.  ...

Energy-efficient bandwidth reservation for bulk data transfers in dedicated wired networks

Anne-Cécile Orgerie, Laurent Lefèvre, Isabelle Guérin-Lassous
2011 Journal of Supercomputing  
The ever increasing number of Internet connected end-hosts call for high performance end-to-end networks leading to an increase in the energy consumed by the networks.  ...  Our work deals with the energy consumption issue in dedicated network with bandwidth provisionning and in-advance reservations of network equipments and bandwidth for Bulk Data transfers.  ...  However, with the emergence of the MPLS (Multi-Protocol Label Switching) [54] standard with traffic engineering and explicit routing features, it becomes possible to disconnect the reservation management  ...

High Performance Commodity Networking in a 512-CPU Teraflop Beowulf Cluster for Computational Astrophysics [article]

John Dubinski, Robin Humble, Ue-Li Pen, Chris Loken, Peter Martin
2003 arXiv   pre-print
The cluster incorporates a cubic network topology based on inexpensive commodity 24-port gigabit switches and point to point connections through the second gigabit port on each Linux server.  ...  We point out that the same cabling effort is required even for more expensive multi-port switches so there is no significant overhead in manual labour.  ...  In the second stage, it was necessary to wire the CDCC network using the point to point connections through the second network port on each node.  ...

Medium access for a military narrowband wireless ad-hoc network; requirements and initial approaches

Lars Erling Braten, Jan Erik Voldhaug, Knut Ovsthus
2008 MILCOM 2008 - 2008 IEEE Military Communications Conference  
In such cases reservation signalling would for example occupy more of the available radio resource when utilising D-TDMA.  ...  For both approaches instability of the contention mechanism(s) during heavy load requires a form of connection admission control to ensure successful outcome of the process for start-up of new traffic  ...  This is quite similar to the OLSR routing protocol where multi relay points (MRPs) are selected.  ...

A survey of internet QoS signaling

Dimitra Vali, Sarantis Paskalis, Lazaros Merakos, Alexandros Kaloxylos
2004 IEEE Communications Surveys and Tutorials  
The need, however, for accommodating network heterogeneity and flexibility, gave birth to a two-tier resource management model that utilizes separate signaling for intra-and inter-domain reservations and  ...  The destination domain edge router is the de-aggregation point for the reservation aggregate, while the source domain edge routers are the aggregation points.  ...  Further flexibility can be achieved by extending the architecture to a multi-tier signaling paradigm.  ...
