Recently, researchers have shown an increased interest in concurrency control using distributed Software Transactional Memory (STM). However, there has been little discussion about certain types of fault tolerance, such as Byzantine Fault Tolerance (BFT), for kind of systems. The focus of this paper is on tolerating byzantine faults on optimistic processing(More)
Clouds are a suitable place to store data with scalability and financial flexibility. However, it is difficult to ensure the reliability of the data stored in a cloud. Byzantine fault tolerance can improve reliability, but at a high cost. This paper presents a technique that anticipates requests in order to reduce that cost. We show that this technique(More)

Scalable and fault-tolerant distributed Software-Defined Networking (SDN) controllers usually give up strong consistency for the network state, adopting instead the more efficient eventually consistent storage model. This decision is mostly due to the performance overhead of the strongly consistent replication protocols (e.g., Paxos, RAFT), which limits the(More)
