Edge computing systems for Industrial Internet of Things (IIoT) applications require reliable
and timely message delivery. Both latency discrepancies within edge clouds, and …

In this article, we propose and evaluate three different state recovery algorithms aimed for
Paxos-one of the most popular distributed agreement protocols. Paxos is commonly used to …

Edge cloud extends the power of cloud computing to the edge of the devices that are closest
to the demands of big connection, low latency and large bandwidth. However, there are still …

The rise of worldwide Internet-scale services demands large distributed systems. Indeed,
when handling several millions of users, it is common to operate thousands of servers …

Many real-time systems nowadays must not only tolerate accidental faults but also targeted
attacks. Typically, techniques such as replication and diversification are used to mask the …

Dependable systems usually rely on replication to provide resilience and availability.
However, for long-lived systems, replication is not enough since given a sufficient amount of …

This paper concisely reviews checkpointing techniques in distributed systems, focusing on
various aspects such as coordinated and uncoordinated checkpointing, incremental …

State machine replication is a fundamental technique to render services fault tolerant. One of
the key assumptions of state machine replication is that replicas must execute operations …

Paxos is one of the most popular protocols for state machine replication (a technique used
for making services highly available). We are the first to propose a Paxos-based state …

Recent research works have shown that applying parallelization to request processing in
Byzantine Fault Tolerance (BFT) can bring significant performance improvement. Based on …
