Brief announcement: a calculus of policy-based routing systems
The BGP (Border Gateway Protocol) is the single inter-domain routing protocol that enables network operators within each autonomous system (AS) to influence routing decisions by ...

Iterative approximate byzantine consensus in arbitrary directed graphs
This paper proves a necessary and sufficient condition for the existence of iterative algorithms that achieve approximate Byzantine consensus in arbitrary directed graphs, where e...

On the (limited) power of non-equivocation
In recent years, there have been a few proposals to add a small amount of trusted hardware at each replica in a Byzantine fault tolerant system to cut back replication factors. Th...

Byzantine broadcast in point-to-point networks using local linear coding
The goal of Byzantine Broadcast (BB) is to allow a set of fault-free nodes to agree on information that a source node wants to broadcast to them, in the presence of Byzantine faul...

The cost of fault tolerance in multi-party communication complexity
Multi-party communication complexity involves distributed computation of a function over inputs held by multiple distributed players. A key focus of distributed computing research...

On the price of equivocation in byzantine agreement
In the Byzantine agreement problem, a set of n processors, any f of whom may be arbitrarily faulty, must reach agreement on a value proposed by one of the correct processors. It i...

Weak models of distributed computing, with connections to modal logic
This work presents a classification of weak models of distributed computing. We focus on deterministic distributed algorithms, and we study models of computing that are weaker ve...

Asynchronous failure detectors
Failure detectors — oracles that provide information about process crashes — are an important ion for crash tolerance in distributed systems. Although current failure-detector...

Faster randomized consensus with an oblivious adversary
Two new algorithms are given for randomized consensus in a shared-memory model with an oblivious adversary. Each is based on a new construction of a conciliator, an object that gu...

Wait-free linked-lists
The linked-list data structure is fundamental and ubiquitous. Lockfree versions of the linked-list are well known. However, the existence of a practical wait-free linked-list has ...
