Devoflow: Scaling flow management for high-performance networks

by Andrew R. Curtis, Jeffrey C. Mogul, Jean Tourrilhes, Praveen Yalag, Puneet Sharma, Sujata Banerjee - In ACM SIGCOMM , 2011
"... OpenFlow is a great concept, but its original design imposes excessive overheads. It can simplify network and traffic management in enterprise and data center environments, because it enables flow-level control over Ethernet switching and provides global visibility of the flows in the network. Howev ..."

Core-Stateless Fair Queueing: Achieving Approximately Fair Bandwidth Allocations in High Speed Networks

by Ion Stoica, Scott Shenker, Hui Zhang , 1998
"... Router mechanisms designed to achieve fair bandwidth allocations, like Fair Queueing, have many desirable properties for congestion control in the Internet. However, such mechanisms usually need to maintain state, manage buffers, and/or perform packet scheduling on a per flow basis, and this complex ..."

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

Developing a Cost-Effective OpenFlow Testbed for Small-Scale Software Defined Networking

by unknown authors
"... Abstract—OpenFlow is the first standard interface for realizing Software-Defined Networking (SDN) that can decouple the data and control plane to provide scalable network management. To validate the performance and features of the OpenFlow standard, many researchers have utilized specialized hardwar ..."

dynamicity and the performance of the virtualized hosts. In this paper, we suggest a more cost-effective alternative of implementing SDN testbed with Open vSwitch (OVS), based on the Raspberry-Pi that is a low-cost embedded Linux machine. We validate our testbed with the OpenFlow specification 1.0 and prove

High-Performance Simulation of Low-Resolution Network Flows

by David M. Nicol, Guanhua Yan
"... Simulation of large-scale networks demands that we model some flows at coarser time scales than others, simply to keep the execution cost manageable. This article studies a method for periodically computing traffic at a time scale larger than that typically used for detailed packet simulations. Appl ..."

Predictor: providing fine-grained management and predictability in multi-tenant datacenter networks

by Daniel S Marcon , Marinho P Barcellos
"... Abstract-Software-Defined Networking (SDN) can simplify traffic management in large-scale datacenter networks (DCNs). On one hand, it provides a robust method to address the challenge of performance interference (bandwidth sharing unfairness) in DCNs. On the other, its pragmatic implementation base ..."

-and inter-application communication, with workconserving bandwidth sharing. Evaluation results show that Predictor provides significant improvements against DevoFlow (reducing flow table size up to 87%) and offers predictable and guaranteed network performance for tenants.

Analysing Logistics Flows in Industrial Clusters Using an Enterprise Input-Output Model

by Vito Albino, Antonio Messeni Petruzzelli , 2006
"... Industrial clusters provide an interesting example of local systems of production that are facing global competition. The firms ’ processes acquire raw materials, convert them into final products, and deliver final products to retailers. Short and long range transfers of materials and energy are bec ..."

In the paper, we propose the use of an enterprise input-output model to analyse logistics flows in order to support coordination policy at the level

Performance Evaluation of Discrete Event Process Algorithms for a Two-Tier High Performance Cloud Computing Network

We explored the various contributions in literature to evolve an Enterprise Energy Analytic Tracking Cloud portal (EEATCP) which must sit on a Two-tier cloud network for optimal service delivery. The proposed architecture offered fault tolerance, improved throughput, scalability, cost-effective
