TLDR
It is shown how the resource reservation in advance scheme can be embedded in a general architecture and the design and implementation of a resource management system providing reservations in advance functionality are described.Abstract:
Resource management offers Quality-of-Service reliability for time-critical continuous-media applications. Currently, existing resource management systems in the Internet and ATM domain only provide means to reserve resources starting with the reservation attempt and lasting for an unspecified duration. However, for several applications such as video conferencing, the ability to reserve the required resources in advance is of great advantage. This paper outlines a new model for resource reservation in advance. We identify and discuss issues to be resolved for allowing resource reservation in advance. We show how the resource reservation in advance scheme can be embedded in a general architecture and describe the design and implementation of a resource management system providing reservation in advance functionality.read more

A distributed resource management architecture that supports advance reservations and co-allocation
TL;DR: The Globus Architecture for Reservation and Allocation (GARA) is proposed, which enables the construction of application-level co-reservation and co-allocation libraries that applications can use to dynamically assemble collections of resources, guided by both application QoS requirements and the local administration policy of individual resources.

SNAP: A Protocol for Negotiating Service Level Agreements and Coordinating Resource Management in Distributed Systems
TL;DR: A resource management model is defined that distinguishes three kinds of resource-independent service level agreements (SLAs), formalizingag reements to deliver capability, perform activities, and bind activities to capabilities, respectively.

A quality of service architecture that combines resource reservation and application adaptation
TL;DR: A QoS architecture, GARA, is described that has been extended to support features of reservations and adaptation, and three examples of application-level adaptive strategies are used to show how this framework can permit applications to adapt both their resource requests and behavior in response to online sensor information.

Resource co-allocation in computational grids
TL;DR: This work presents mechanisms that allow an application to guide resource selection during the co-allocation process and describes the implementation of co-allocators based on these mechanisms and the results of microbenchmark studies and large-scale application experiments that provide insights into the costs and practical utility of the techniques.

End-to-end quality of service for high-end applications
TL;DR: The prototype GARA implementation builds on differentiated services mechanisms to enable the coordinated management of two distinct flow types-foreground media flows and background bulk transfers-as well as the co-reservation of networks, CPUs, and storage systems.

Scheduling algorithms for multiprogramming in a hard real-time environment
C. L. Liu,James W. Layland +1 more
TL;DR: In this paper, the problem of multiprogram scheduling on a single processor is studied from the viewpoint of the characteristics peculiar to the program functions that need guaranteed service, and it is shown that an optimum fixed priority scheduler possesses an upper bound to processor utilization which may be as low as 70 percent for large task sets.

RSVP: a new resource ReSerVation Protocol
TL;DR: The resource reservation protocol (RSVP) as discussed by the authors is a receiver-oriented simplex protocol that provides receiver-initiated reservations to accommodate heterogeneity among receivers as well as dynamic membership changes.

Supporting real-time applications in an Integrated Services Packet Network: architecture and mechanism
TL;DR: This paper considers the support of real-time applications in an Integrated Services Packet Network (ISPN), and proposes an ISPN architecture that supports two distinct kinds of real time service: guaranteed service, which involves pre-computed worst-case delay bounds, and predicted service which uses the measure performance of the network in computing delay bounds.

RSVP: a new resource reservation protocol
TL;DR: A resource reservation protocol (RSVP), a flexible and scalable receiver-oriented simplex protocol, that provides receiver-initiated reservations to accommodate heterogeneity among receivers as well as dynamic membership changes and supports a dynamic and robust multipoint-to-multipoint communication model.

Human perception of jitter and media synchronization
TL;DR: The results show that skews between related data streams may still give the effect that the data is 'in sync' and the author uses the findings to develop a scheme for the processing of nontrivial synchronization skew between more than two data streams.
