This paper proposes a method, called RLR (RSVP (Resource reSerVation Protocol) library redirection), which can transform legacy Internet applications into RSVP-aware applications without modifying their source files by redirecting procedure calls from the socket library to the RAPI library

to illustrate how to transform legacy applications into RSVP-aware. We also deploy a user interface for users to adjust their reservation requirement. I.

) for the delay-sensitive receivers. This paper presents a RSVP-aware RG that provides the RSVP library redirection mechanism (refer to QLR [8]) in RSVP-enable IntServ network, which makes legacy Internet applications RSVP-aware in the run-time. So it can guarantee the network bandwidth to meet the real

files, checkpointing remains unavailable to most application developers. In this paper we describe libckpt, a portable checkpointing tool for Unix that implements all applicable performance optimizations which are reported in the literature. While libckpt can be used in a mode whichis almost totally

In this paper we show that application-aware adaptation, a collaborative partnership between the operating system and applications, offers the most general and effective approach to mobile information access. We describe the design of Odyssey, a prototype implementing this approach, and show how

We describe a platform for context-aware computing which enables applications to follow mobile users as they move around a building. The platform is particularly suitable for richly equipped, networked environments. The only item a user is required to carry is a small sensor tag, which identifies

be minimized by deploying a kernel agent called a packet filter, which discards unwanted packets as early as possible. The original Unix packet filter was designed around a stack-based filter evaluator that performs sub-optimally on current RISC CPUs. The BSD Packet Filter (BPF) uses a new, registerbased

A fundamental problem that confronts peer-to-peer applications is to efficiently locate the node that stores a particular data item. This paper presents Chord, a distributed lookup protocol that addresses this problem. Chord provides support for just one operation: given a key, it maps the key onto

removed from that vision. This is due to three main problems: (1) the notion of context is still ill defined; (2) there is a lack of conceptual models and methods to help drive the design of context-aware applications; and (3) no tools are available to jump-start the development of context-aware

. In this article, we introduce Globus, a system that we are developing to address these challenges. The Globus system is intended to achieve a vertically integrated treatment of application, middleware, and network. A low-level toolkit provides basic mechanisms such as communication, authentication, network
