ElasticTree: Saving Energy in Data Center Networks
TLDR
This work presents ElasticTree, a network-wide power1 manager, which dynamically adjusts the set of active network elements -- links and switches--to satisfy changing data center traffic loads, and demonstrates that for data center workloads, ElasticTree can save up to 50% of network energy, while maintaining the ability to handle traffic surges.

DevoFlow: scaling flow management for high-performance networks
TLDR
DevoFlow is designed and evaluated, a modification of the OpenFlow model which gently breaks the coupling between control and global visibility, in a way that maintains a useful amount of visibility without imposing unnecessary costs. Expand
DevoFlow: scaling flow management for high-performance networks
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 enablesExpand
Protocol Independent Multicast-Sparse Mode (PIM-SM): Protocol Specification
This document specifies Protocol Independent Multicast - Sparse Mode (PIM-SM). PIM-SM is a multicast routing protocol that can use the underlying unicast routing information base or a separateExpand
PGA: Using Graphs to Express and Automatically Reconcile Network Policies
TLDR
This work first develops a high-level Policy Graph Abstraction (PGA) that allows network policies to be expressed simply and independently, and leverage the graph structure to detect and resolve policy conflicts efficiently, and also models and composes service chaining policies. Expand
A Power Benchmarking Framework for Network Devices
TLDR
The hurdles in network power instrumentation are described and a power measurement study of a variety of networking gear such as hubs, edge switches, core switches, routers and wireless access points in both stand-alone mode and a production data center are presented. Expand
Energy Aware Network Operations
TLDR
This paper describes and analyzes three approaches to saving energy in single administrative domain networks, without significantly impacting the networks' ability to provide the expected levels of performance and availability, and explores the trade-offs between conserving energy and meeting performance andavailability requirements. Expand
DevoFlow: cost-effective flow management for high performance enterprise networks
TLDR
DevoFlow is proposed, a modification of the OpenFlow model in which it is proposed to gently break the coupling between centralized control and centralized visibility, in a way that maintains a useful amount of visibility without imposing unnecessary costs. Expand
Automated and Scalable QoS Control for Network Convergence
TLDR
A network QoS control framework for converged fabrics that automatically and flexibly programs a network of devices with the necessary QoS parameters, derived from a high level set of application requirements is proposed. Expand
