dRBAC: distributed role-based access control for dynamic coalition environments
Proceedings - International Conference on Distributed Computing Systems - - Trang 411-420
E. Freudenthal, T. Pesin, L. Port, E. Keenan, V. Karamcheti
distributed role-based access control (dRBAC) is a scalable, decentralized trust-management and access-control mechanism for systems that span multiple administrative domains. dRBAC utilizes PKI identities to define trust domains, roles to define controlled activities, and role delegation across domains to represent permissions to these activities. The mapping of controlled actions to roles enable...... hiện toàn bộ

Fast Collect in the absence of contention
Proceedings - International Conference on Distributed Computing Systems - - Trang 537-543
B. Englert, E. Gafni
We present a generic module, called Fast Collect. Fast Collect is an implementation of single-writer multi-reader (SWMR) shared-memory in an asynchronous system in which a processor updates its cell and then reads in any order all the other cells. Our simple implementation of Fast Collect uses some multiwriter multi-reader (MWMR) variables and one local Boolean per processor, such that eventually,...... hiện toàn bộ

Scheduling real-time data items in multiple channels and multiple receivers environments
Proceedings - International Conference on Distributed Computing Systems - - Trang 455-456
Guanling Lee, Yi-Ning Pan, A.L.P. Chen
The problem of transmitting data items with timing constraint in the multiple broadcast channels where clients equipped with multiple receivers is studied. In our approach, the data items are divided into two sets, the broadcast data set and the on-demand data set. The data items in the broadcast data set is periodically broadcast on the broadcast channels while the data items in the on-demand dat...... hiện toàn bộ

Dining philosophers that tolerate malicious crashes
Proceedings - International Conference on Distributed Computing Systems - - Trang 191-198
M. Nesterenko, A. Arora
We present a solution to the problem of dining philosophers. Our solution tolerates malicious crashes. In a malicious crash the failed process behaves arbitrarily for a finite time and then ceases all operation undetectably to other processes. The tolerance of our solution is achieved by the combination of stabilization and crash failure locality. Stabilization allows our program to recover from a...... hiện toàn bộ

The totem redundant ring protocol
Proceedings - International Conference on Distributed Computing Systems - - Trang 598-607
R.R. Koch, L.E. Moser, P.M. Melliar-Smith
Group communication protocols greatly simplify the design of fault-tolerant distributed systems. Most of those protocols focus on node redundancy rather than on network redundancy. The totem redundant ring protocol allows the use of multiple redundant local-area networks. The partial or total failure of a network remains transparent to the application processes. The distributed system remains oper...... hiện toàn bộ

RICA: a receiver-initiated approach for channel-adaptive on-demand routing in ad hoc mobile computing networks
Proceedings - International Conference on Distributed Computing Systems - - Trang 84-91
Xiao-Hui Lin, Yu-Kwong Kwok, V.K.N. Lau
To support truly peer-to-peer applications in ad hoc wireless mobile computing networks, a judicious and efficient ad hoc routing protocol is needed. Much research has been done on designing ad hoc routing protocols and some well known protocols are also being implemented in practical situations. However, one major drawback in existing state-of-the-art protocols, such as the AODV routing protocol,...... hiện toàn bộ

Distributing MPEG movies over the Internet using programmable networks
Proceedings - International Conference on Distributed Computing Systems - - Trang 161-170
D. He, G. Muller, J.L. Lawall
Distributing video over the Internet is an increasingly important application. Nevertheless, the real-time and high bandwidth requirements of video make video distribution over today's Internet a challenge. Adaptive approaches can be used to respond to changes in bandwidth availability while limiting the effect of such changes on perceptual quality and resource consumption. Nevertheless, most exis...... hiện toàn bộ

OS support for P2P programming: a case for TPS
Proceedings - International Conference on Distributed Computing Systems - - Trang 355-362
S. Baehni, P.T. Eugster, R. Guerraoui
Just as the remote procedure call (RPC) turned out to be a very effective OS abstraction in building client-server applications over LANs, type-based publish-subscribe (TPS) can be viewed as a high-level candidate abstraction for building peer-to-peer (P2P) applications over WANs. This paper relates our preliminary, though positive, experience of implementing and using TPS over JXTA, which can be ...... hiện toàn bộ

Dynamic data broadcasting with traffic awareness
Proceedings - International Conference on Distributed Computing Systems - - Trang 112-119
Chih-Lin Hu, Ming-Syan Chen
Data dissemination has significantly served as a scalable data delivery mechanism in wireless networks. However, even though the broadcast traffic has the nature of dynamic changes, most previous research efforts were elaborated upon the premise of static workloads and access patterns without having proper traffic awareness. In this paper, we address the existence of client impatience and accordin...... hiện toàn bộ
