This paper presents the abstraction of open consensus and argues for its use as an effective component for building reliable agreement protocols in practical asynchronous systems where processes and links can crash and recover. The specification of open co ...
This paper presents the abstraction of lazy consensus and argues for its use as an effective component for building distributed agreement protocols in practical asynchronous systems where processes and links can crash and recover. Lazy consensus looks like ...
This paper addresses the problem of broadcasting messages in a reliable and totally ordered manner when processes and channels may crash and recover, or crash and never recover. We present a suite of specifications of reliable and total order broadcast pri ...
Leasing is a very effective way to improve the performance of distributed algorithms without hampering their fault-tolerance. The notion of lease has traditionally been defined using a global notion of time and was hence strongly tied to synchronous system ...
The Paxos part-time parliament protocol of Lamport provides a non trivial but very practical way to implement fault-tolerant deterministic services over a distributed message passing system. This paper deconstructs Paxos and modularly reconstructs more res ...
