Rethinking virtual network embedding: substrate support for path splitting and migration
TLDR
This paper simplifies virtual link embedding by allowing the substrate network to split a virtual link over multiple substrate paths and employing path migration to periodically re-optimize the utilization of the substrates network. Expand
SIMPLE-fying middlebox policy enforcement using SDN
TLDR
SIMPLE, a SDN-based policy enforcement layer for efficient middlebox-specific "traffic steering", is presented, a significant step toward addressing industry concerns surrounding the ability of SDN to integrate with existing infrastructure and support L4-L7 capabilities. Expand
Software Defined Traffic Measurement with OpenSketch
TLDR
This work proposes a software defined traffic measurement architecture OpenSketch, which separates the measurement data plane from the control plane and provides a measurement library that automatically configures the pipeline and allocates resources for different measurement tasks. Expand
CherryPick: Adaptively Unearthing the Best Cloud Configurations for Big Data Analytics
TLDR
CherryPick is a system that leverages Bayesian Optimization to build performance models for various applications, and the models are just accurate enough to distinguish the best or close-to-the-best configuration from the rest with only a few test runs. Expand
FlowRadar: A Better NetFlow for Data Centers
TLDR
The key idea of FlowRadar is to encode perflow counters with a small memory and constant insertion time at switches, and then to leverage the computing power at the remote collector to perform network-wide decoding and analysis of the flow counters. Expand
Rapier: Integrating routing and scheduling for coflow-aware data center networks
TLDR
This work presents Rapier, a coflow-aware network optimization framework that seamlessly integrates routing and scheduling for better application performance, and demonstrates that Rapier significantly reduces the average coflow completion time. Expand
SilkRoad: Making Stateful Layer-4 Load Balancing Fast and Cheap Using Switching ASICs
TLDR
The system, called SilkRoad, is defined in a 400 line P4 program and when compiled to a state-of-the-art switching ASIC, it can load-balance ten million connections simultaneously at line rate. Expand
DREAM: dynamic resource allocation for software-defined measurement
TLDR
An adaptive measurement framework, called DREAM, that dynamically adjusts the resources devoted to each measurement task, while ensuring a user-specified level of accuracy, is described. Expand
Scalable flow-based networking with DIFANE
TLDR
DIFANE is proposed, a scalable and efficient solution that keeps all traffic in the data plane by selectively directing packets through intermediate switches that store the necessary rules. Expand
