DeepDive: Transparently Identifying and Managing Performance Interference in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini, Stanko Novakovic

Cloud computing in general, and Infrastructure-as-a-Service (IaaS) in particular, are becoming ever more popular. Unfortunately, performance interference (and the resulting unpredictability in the delivered performance) across virtual machines (VMs) co-loc ...

OF.CPP: Consistent Packet Processing for OpenFlow

Dejan Kostic, Marco Canini, Peter Peresini, Maciej Leszek Kuzniar, Nedeljko Vasic

This paper demonstrates a new class of bugs that is likely to occur in enterprise OpenFlow deployments. In particular, step-by-step, reactive establishment of paths can cause network-wide inconsistencies or performance- and space-related inefficiencies. Th ...

DejaVu: Accelerating Resource Allocation in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini

Effective resource management of virtualized environments is a challenging task. State-of-the-art management systems either rely on analytical models or evaluate resource allocations by running actual experiments. However, both approaches incur a significa ...

Acm Order Department, P O Box 64145, Baltimore, Md 21264 Usa2012

The power consumption of the Internet and datacenter networks is already significant due to a large degree of redundancy and high idle power consumption of the network elements. Therefore, dynamically matching network resources to the actual load is highly ...

Bandwidth Adaptation in Streaming Overlays

Dejan Kostic, Nedeljko Vasic, Simon Schubert

A major challenge for real-time streaming overlays is to distribute high bit-rate streams with uninterrupted playback. Hosts usually have sufficient inbound bandwidth to support streaming, but due to the prevalence of asymmetric links in broadband networks ...
