Kevin: de Bruijn-based topology with demand-aware links and greedy routing
Johannes Zerwas, Csaba Györgyi, Andreas Blenk +2
We propose Kevin, a novel demand-aware reconfigurable rack-to-rack datacenter network realized with a simple and efficient control plane. In particular, Kevin makes effective use o…
Performance Analysis of Demand-Oblivious and Demand-Aware Optical Datacenter Network Designs
Chen Griner, Johannes Zerwas, Andreas Blenk +3
This paper presents a performance analysis of the design space of optical datacenter networks, including both demand-oblivious (static or dynamic) and demand-aware networks. We for…
Scalable Application- and User-aware Resource Allocation in Enterprise Networks Using End-host Pacing
Christian Sieber, Susanna Schwarzmann, Andreas Blenk +2
Scalable user- and application-aware resource allocation for heterogeneous applications sharing an enterprise network is still an unresolved problem. The main challenges are: (i) H…
Logically Isolated, Actually Unpredictable? Measuring Hypervisor Performance in Multi-Tenant SDNs
Arsany Basta, Andreas Blenk, Wolfgang Kellerer +1
Ideally, by enabling multi-tenancy, network virtualization allows to improve resource utilization, while providing performance isolation: although the underlying resources are shar…
Optimization Models for Flexible and Adaptive SDN Network Virtualization Layers
Johannes Zerwas, Andreas Blenk, Wolfgang Kellerer
Network hypervisors provide the network virtualization layer for Software Defined Networking (SDN). They enable virtual network (VN) tenants to bring their SDN controllers to progr…
Flexibility of Networks: a new measure for network design space analysis?
Wolfgang Kellerer, Arsany Basta, Andreas Blenk
Flexibility is often claimed as a competitive advantage when proposing new network designs. However, most proposals provide only qualitative arguments for their improved support of…
Survey on Network Virtualization Hypervisors for Software Defined Networking
Andreas Blenk, Arsany Basta, Martin Reisslein +1
Software defined networking (SDN) has emerged as a promising paradigm for making the control of communication networks flexible. SDN separates the data packet forwarding plane, i.e…
