We will discuss design issues for group communication, Amoeba's group system calls, and the protocols to implement group communication. To demonstrate that group communication is a useful abstraction, we will describe a design and implementation of a fault-tolerant directory service. We discuss two versions of the directory service: one with Non-Volatile RAM (NVRAM) and one without NVRAM. We will give performance figures for both implementations.

Providing both reliability and scalability at the same time is hard. Commodity OS architectures simply lack the design abstractions to do so for demanding core OS services such as the network stack. For reliability and scalability guarantees, they rely almost exclusively on ensuring a high-quality implementation, rather than a reliable and scalable design. This results in complex error recovery paths and hard-to-maintain synchronization code. We demonstrate that a simple and structured design that strictly adheres to two principles, isolation and partitioning, can yield reliable and scalable network stacks. We present NEaT, a system which partitions the stack across isolated process replicas handling independent requests. Our design principles intelligently partition the state to minimize the impact of failures (offering strong recovery guarantees) and to scale comparably to Linux without exposing the implementation to common pitfalls such as synchronization errors, poor locality, and false sharing.

Roadmap to a faillure-resilient operating sistem

Traditional solutions rely on partitioning the operating system (OS) to contain the effects of crashes within compartments and facilitate modular recovery. However, state dependencies among the compartments hinder recovery that is globally consistent. Such recovery typically requires expensive runtime dependency tracking which results in high performance overhead, high complexity and a large Reliable Computing Base (RCB). We propose a lightweight strategy that limits recovery to cases where we can statically and conservatively prove that compartment recovery leads to a globally consistent statetrading recoverable surface for a simpler and smaller RCB with lower performance overhead and maintenance cost. We present OSIRIS, a research OS design prototype that demonstrates efficient and consistent crash recovery. Our evaluation shows that OSIRIS effectively recovers from important classes of real-world software bugs with a modest RCB and low overheads.

To demonstrate the feasibility of our design and to test our ideas, we are currently building a new Internet application: The Globe Distribution Network. The Globe Distribution Network, or GDN, is an application for the efficient, worldwide distribution of free software and other free data. The GDN can be seen as an improvement to anonymous ...

This is partly explained by the many facets of such systems and the inherent difficulty to isolate these facets from each other. In this paper we provide a brief overview of distributed systems: what they are, their general design goals, and some of the most common types.

Distribution is made efficient by encapsulating the software into special distributed objects which efficiently replicate themselves near to the downloading clients. The Globe Distribution Network takes a novel, optimistic approach to stop the illegal distribution of copyrighted and illicit material via the network. Instead of having moderators check the packages at upload time, illegal content is removed and its uploader’s access to the network permanently revoked only when the violation is discovered. Other protective measures defend the GDN against internal and external attacks at its availability. By exploiting the replication of the software and using fault-tolerant server software, the Globe Distribution Network achieves high availability. This article describes the design of the GDN and a number of small experiments with its prototype implementation. 1
