SEER: Performance-Aware Leader Election in Single-Leader Consensus
Ermin Sakic, Petra Vizarreta, Wolfgang Kellerer
Modern stateful web services and distributed SDN controllers rely on log replication to omit data loss in case of fail-stop failures. In single-leader execution, the leader replica…
P4BFT: Hardware-Accelerated Byzantine-Resilient Network Control Plane
Ermin Sakic, Nemanja Deric, Endri Goshi +1
Byzantine Fault Tolerance (BFT) enables correct operation of distributed, i.e., replicated applications in the face of malicious take-over and faulty/buggy individual instances. Re…
Rule-Based Translation of Application-Level QoS Constraints into SDN Configurations for the IoT
Jan Seeger, Arne Bröring, Marc-Oliver Pahl +1
In this paper, we propose an approach for the automated translation of application-level requirements regarding the logical workflow and its QoS into a configuration of the underly…
BFT Protocols for Heterogeneous Resource Allocations in Distributed SDN Control Plane
Ermin Sakic, Wolfgang Kellerer
Distributed Software Defined Networking (SDN) controllers aim to solve the issue of single-point-of-failure and improve the scalability of the control plane. Byzantine and faulty c…
Towards adaptive state consistency in distributed SDN control plane
Ermin Sakic, Fragkiskos Sardis, Jochen W. Guck +1
State synchronisation in clustered Software Defined Networking controller deployments ensures that all instances of the controller have the same state information in order to provi…
MORPH: An Adaptive Framework for Efficient and Byzantine Fault-Tolerant SDN Control Plane
Ermin Sakic, Nemanja Ðerić, Wolfgang Kellerer
Current approaches to tackle the single point of failure in SDN entail a distributed operation of SDN controller instances. Their state synchronization process is reliant on the as…
Impact of Adaptive Consistency on Distributed SDN Applications: An Empirical Study
Ermin Sakic, Wolfgang Kellerer
Scalability of the control plane in a software-defined network (SDN) is enabled by means of decentralization of the decision-making logic, i.e., by replication of controller functi…
VirtuWind - An SDN- and NFV-based Architecture for Softwarized Industrial Networks
Ermin Sakic, Vivek Kulkarni, Vasileios Theodorou +4
VirtuWind proposes the application of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) in critical infrastructure networks. We aim at introducing networ…
Response Time and Availability Study of RAFT Consensus in Distributed SDN Control Plane
Ermin Sakic, Wolfgang Kellerer
Software defined networking (SDN) promises unprecedented flexibility and ease of network operations. While flexibility is an important factor when leveraging advantages of a new te…
