Disk failures in the real world: What does an MTTF of 1,000,000 hours mean to you?
, 2007
"... Component failure in large-scale IT installations is becoming an ever larger problem as the number of components in a single cluster approaches a million. In this paper, we present and analyze field-gathered disk replacement data from a number of large production systems, including high-performance ..."

,000,000 to 1,500,000 hours, suggesting a nominal annual failure rate of at most 0.88%. We find that in the field, annual disk replacement rates typically exceed 1%, with 2-4 % common and up to 13% observed on some systems. This suggests that field replacement is a fairly different process than one might
Lightweight Agents For Intrusion Detection
- Journal of Systems and Software
, 2000
"... We have designed and implemented an intrusion detection system prototype based on mobile agents. Our agents travel between monitored systems in a network of distributed systems, obtain information from data cleaning agents, classify & correlate information, and report the information to a user ..."

and collaboration capabilities to the mobile agents in our intrusion detection system. 1 Introduction A secure computer system provides guarantees regarding the condentiality, integrity, and availability of its objects (such as data, processes, or services). However, systems generally contain design
Communication Models for Processes and Services in Mobile Lightweight Grid Systems
"... The last few years we have seen the emergence of pervasive and mobile computing technologies. At the same time the Grid has become the de facto standard for distributed and high performance computing. A lightweight Grid infrastructure may well provide a solid foundation for pervasive computing. For ..."

Chant: Lightweight Threads in a Distributed Memory Environment
- in Journal of Parallel and Distributed Programming
, 1995
"... Lightweight threads are becoming increasingly useful in supporting parallelism and asynchronous events in applications and language implementations. Traditionally, lightweight threads are supported only within the single address space of a process, or in shared memory environments with multiple pr ..."

processes. We introduce and describe the design of Chant, a runtime system supporting lightweight threads in a distributed memory environment. In addition to communication between any two threads in the system, Chant provides support for remote service requests, remote thread operations, and collective
Partitionable Light-Weight Groups
- In 20th IEEE International Conference on Distributed Computing Systems (ICDCS’20
, 2000
"... Group communication, providing virtual synchrony semantics, is a powerful paradigm for building distributed applications. For applications that require a large number of groups, significant performance gains can be attained if these groups share the resources required to provide virtual synchrony ..."

The paper focuses on the design of reconciliation mechanisms needed when a partition is healed. 1 Introduction For developing distributed applications, virtually synchronous group
A Lightweight Awareness Service for Industrial Environments
- HICSS 30, Mini-track on Software Engineering for Distributed Systems at Software Technology Track
"... This paper presents the design and implementation of a lightweight awareness service and its application to example scenarios of distributed software environments. Due to the complexity of distributed systems, the behavior of software for distributed systems is hard to predict. Even examining the be ..."

A Signaling System Using Lightweight Call Sessions
- In Proceedings of IEEE INFOCOM, Tel-Aviv
, 2000
"... Because of the emergence of heterogeneous access devices and diverse wired and wireless networks, and a substantial lack of support for integrating these networks, we are building a communication network and a service infrastructure that provides integrated telephony and data services across these n ..."

Call setup has already been addressed by protocols such as Session Initiation Protocol (SIP) [1]), so we focus on a missing component: scalable and fault
A robust and lightweight stable leader election service for dynamic systems
- In Proceedings of DSN’08
, 2008
"... We describe the implementation and experimental evalu-ation of a fault-tolerant leader election service for dynamic systems. Intuitively, distributed applications can use this service to elect and maintain an operational leader for any group of processes which may dynamically change. If the leader o ..."

Future advances in networking and storage will make it feasible to build multimedia on-demand servers that provide services similar to those of a neighborhood videotape rental store over metropolitan area networks such as B-ISDN. Such multimedia servers can support real-time retrieval of multimedia ..."
