Epidemic Routing for Partially-Connected Ad Hoc Networks
This work introduces Epidemic Routing, where random pair-wise exchanges of messages among mobile hosts ensure eventual message delivery and achieves eventual delivery of 100% of messages with reasonable aggregate resource consumption in a number of interesting scenarios. Expand
A scalable, commodity data center network architecture
This paper shows how to leverage largely commodity Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements and argues that appropriately architected and interconnected commodity switches may deliver more performance at less cost than available from today's higher-end solutions.

B4: experience with a globally-deployed software defined wan
This work presents the design, implementation, and evaluation of B4, a private WAN connecting Google's data centers across the planet, using OpenFlow to control relatively simple switches built from merchant silicon. Expand
Hedera: Dynamic Flow Scheduling for Data Center Networks
Hedera is presented, a scalable, dynamic flow scheduling system that adaptively schedules a multi-stage switching fabric to efficiently utilize aggregate network resources and delivers bisection bandwidth that is 96% of optimal and up to 113% better than static load-balancing methods. Expand
Helios: a hybrid electrical/optical switch architecture for modular data centers
This work presents Helios, a hybrid electrical/optical switch architecture that can deliver significant reductions in the number of switching elements, cabling, cost, and power consumption relative to recently proposed data center network architectures. Expand
PortLand: a scalable fault-tolerant layer 2 data center network fabric
Through the design and implementation of PortLand, a scalable, fault tolerant layer 2 routing and forwarding protocol for data center environments, it is shown that PortLand holds promise for supporting a ``plug-and-play" large-scale, data center network. Expand
P4: programming protocol-independent packet processors
This paper proposes P4 as a strawman proposal for how OpenFlow should evolve in the future, and describes how to use P4 to configure a switch to add a new hierarchical label. Expand
Managing energy and server resources in hosting centers
Experimental results from a prototype confirm that the system adapts to offered load and resource availability, and can reduce server energy usage by 29% or more for a typical Web workload. Expand
Hyperbolic Geometry of Complex Networks
It is shown that targeted transport processes without global topology knowledge are maximally efficient, according to all efficiency measures, in networks with strongest heterogeneity and clustering, and that this efficiency is remarkably robust with respect to even catastrophic disturbances and damages to the network structure.
