TLDR
The Horus system offers flexible group communication support for distributed applications, allowing applications to only pay for services they use, and for groups with different communication needs to coexist in a single system.
Abstract
The Horus system offers flexible group communication support for distributed applications. It is extensively layered and highly reconfigurable, allowing applications to only pay for services they use, and for groups with different communication needs to coexist in a single system. The approach encourages experimentation with new communication properties and incremental extension of the system, and enables us to support a variety of application-oriented interfaces.

A multicast scheme for parallel software-only video effects processing

TL;DR: An optimization that provides a flexible framework for linking the control of different aspects of one or more related video effects that uses IP-Multicast, the Scalable Reliable Multicast protocol, and the Scalables Naming and Announcement Protocol is described.

Group-Oriented Communication: Concept and Network Architecture

TL;DR: This paper qualitatively discusses advantages of the group-oriented communication by comparing with the conventional IP-based network, and discusses four design goals of a network architecture for the authors' group- oriented communication: supporting dynamic entity/group, supporting address operation expression, realization of entity/ group find ability, and realization of security.

A reliable multicast framework for light-weight sessions and application level framing

TL;DR: An adaptive algorithm that uses the results of previous loss recovery events to adapt the control parameters used for future loss recovery is demonstrated, and the reliable multicast delivery algorithm provides good performance over a wide range of underlying topologies.

Probabilistic clock synchronization

TL;DR: A probabilistic method is proposed for reading remote clocks in distributed systems subject to unbounded random communication delays and can achieve clock synchronization precisions superior to those attainable by previously published clock synchronization algorithms.

Hypervisor-based fault tolerance

TL;DR: In this article, the authors describe protocols to implement a fault-tolerant computing system, which augment the hypervisor of a virtual machine manager and coordinate a primary virtual machine with its backup.
