- Scaling Byzantine Fault-Tolerant Replication to Wide Area Networks
- This paper presents the first hierarchical Byzantine fault-tolerant replication architecture suitable to systems that span multiple wide area sites. The architecture confines the effects of any malicious replica to its local site, reduces message complexity of wide area communication, and allows read-only queries to be performed locally within a site...

- Fault-Scalable Byzantine Fault-Tolerant Services
- A fault-scalable service can be configured to tolerate increasing numbers of faults without significant decreases in performance. The Query/Update (Q/U) protocol is a new tool that enables construction of fault-scalable Byzantine fault-tolerant services. The optimistic quorum-based nature of the Q/U protocol allows it to provide better throughput and fault-scalability than...

- A Hybrid Fault-Tolerant Algorithm for MPLS Networks
- This paper presents a new fault tolerant, path maintaining, algorithm for use in MPLS based networks. The novelty of the algorithm lies upon the fact that it is the first to employ both path restoration mechanisms typically used in MPLS networks: protection switching and dynamic path rerouting. In addition, it...
