An extensible and scalable Content Adaptation Pipeline architecture to support heterogeneous clients - Trang 507-516
T. Phan, G. Zorpas, R. Bagrodia
The importance of middleware and content adaptation has previously been
demonstrated for pervasive use of Web-based applications. In this paper we
propose a modular extensible, and scalable middleware component called the
Content Adaptation Pipeline that performs content adaptation on arbitrarily
complex data types not limited to text and graphic images. Furthermore, the
architecture can be used a... hiện toàn bộ

A fully distributed framework for cost-sensitive data mining - Trang 445-446
Wei Fan, Haixun Wang, P.S. Yu, S.J. Stolfo
We propose a fully distributed system (as compared to centralized and partially
distributed systems) for cost-sensitive data mining. Experimental results have
shown that this approach achieves higher accuracy than both the centralized and
partially distributed learning methods, however, it incurs much less training
time, neither communication nor computation overhead.

Reasoning about joint administration of access policies for coalition resources - Trang 429-438
H. Khurana, V. Gligor, J. Linn
We argue that joint administration of access policies for a dynamic coalition
formed by autonomous domains requires that these domains set up a coalition
authority that distributes attribute certificates authorizing access to policy
objects (e.g., ACLs). Control over the issuance of such certificates is retained
by member domains separately holding shares of the joint coalition authority's
private... hiện toàn bộ

Process migration: a generalized approach using a virtualizing operating system - Trang 385-392
T. Boyd, P. Dasgupta
Process migration has been used to perform specialized tasks, such as load
sharing and checkpoint/restarting long running applications. Implementation
typically consists of modifications to existing applications and the creation of
specialized support systems, which limit the applicability of the methodology.
Off the shelf applications have not benefited from process migration
technologies, mainly... hiện toàn bộ

Design of a policy-driven middleware for secure distributed collaboration - Trang 393-400
A.R. Tripathi, T. Ahmed, R. Kumar, S. Jaman
We present the execution model of policy-driven middleware for building secure
distributed collaboration systems from their high level specifications. Our
specification model supports nested collaboration activities, and uses
role-based security policies and event count based coordination specification.
From the specifications of a collaboration environment, appropriate policy
modules are derived ... hiện toàn bộ

Accelerating Internet streaming media delivery using network-aware partial caching - Trang 153-160
Shudong Jin, A. Bestavros, A. Iyengar
Internet streaming applications are affected by adverse network conditions such
as high packet loss rates and long delays. This paper aims at mitigating such
effects by leveraging the availability of client-side caching proxies. We
present a novel caching architecture and associated cache management algorithms
that turn edge caches into accelerators of streaming media delivery. A salient
feature o... hiện toàn bộ

An optimal strategy for anonymous communication protocols - Trang 257-266
Yong Guan, Xinwen Fu, R. Bettati, Wei Zhao
For many Internet applications, the ability to protect the identity of
participants in a distributed applications is critical. For such applications, a
number of anonymous communication systems have been realized over the recent
years. The effectiveness of these systems relies greatly on the way messages are
routed among the participants. (We call this the route selection strategy.) In
this paper ... hiện toàn bộ

Key trees and the security of interval multicast - Trang 467-468
M.G. Gouda, Chin-Tser Huang, E.N. Elnozahy
A key tree is a distributed data structure of security keys that can be used by
a group of users. In this paper we describe how any user in the group can use
the different keys in the key tree to securely multicast data to different
subgroups within the group. The cost of securely multicasting data to a subgroup
whose users are "consecutive" is O(log n) encryptions, where n is the total
number of ... hiện toàn bộ

Distributing MPEG movies over the Internet using programmable networks - 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

Improving search in peer-to-peer networks - Trang 5-14
B. Yang, H. Garcia-Molina
Peer-to-peer systems have emerged as a popular way to share huge volumes of
data. The usability of these systems depends on effective techniques to find and
retrieve data; however current techniques used in existing P2P systems are often
very inefficient. We present three techniques for efficient search in P2P
systems. We present the design of these techniques, and then evaluate them using
a combi... hiện toàn bộ
