Multimedia networks with deterministic quality-of-service guarantees

by Dallas E. Wrege , 1996
"... Future integrated-services networks are expected to support applications with a wide range of service requirements. The most demanding applications require a bounded-delay service that provides deterministic (i.e., worst-case) bounds on network latencies for all packets. To provide such delay guaran ..."

Exploiting the Temporal Structure of MPEG Video for the Reduction of Bandwidth Requirements

by Marwan Krunz, Satish Tripathi - in Proc. of IEEE Infocom , 1997
"... We propose a new bandwidth allocation scheme for VBR video traffic in ATM networks. The scheme is tailored to MPEG-coded video sources that require stringent and deterministic quality-of-service guarantees. By exploiting the temporal structure of MPEG sources, we show that our scheme results in an e ..."

Quality of Service Guarantees in Virtual Circuit Switched Networks

by R. L. Cruz - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 1995
"... We review some recent results regarding the problem of providing deterministic quality of service guarantees in slot-based virtual circuit switched networks. The concept of a service curve is used to partially characterize the service that virtual circuit connections receive. We find that service cu ..."

Coverage Problems in Wireless Ad-hoc Sensor Networks

by Seapahn Meguerdichian, Farinaz Koushanfar, Miodrag Potkonjak, Mani B. Srivastava - in IEEE INFOCOM , 2001
"... Wireless ad-hoc sensor networks have recently emerged as a premier research topic. They have great longterm economic potential, ability to transform our lives, and pose many new system-building challenges. Sensor networks also pose a number of new conceptual and optimization problems. Some, such as ..."

, such as location, deployment, and tracking, are fundamental issues, in that many applications rely on them for needed information. In this paper, we address one of the fundamental problems, namely coverage. Coverage in general, answers the questions about quality of service (surveillance) that can be provided

Quality-of-Service Routing for Traffic with Performance Guarantees

by Qingming Ma, Peter Steenkiste - In Proc. IFIP International Workshop on Quality of Service , 1997
"... Quality-of-Service (QoS) routing tries to select a path that satisfies a set of QoS constraints, while also achieving overall network resource efficiency. We present initial results on QoS path selection for traffic requiring bandwidth and delay guarantees. For traffic with bandwidth guarantees, we ..."

Providing Guaranteed Services Without Per Flow Management

by Ion Stoica, Hui Zhang
"... Existing approaches for providing guaranteed services require routers to manage per flow states and perform per ow operations [9, 21]. Such a stateful network architecture is less scalable and robust than stateless network architectures like the original IP and the recently proposed Diffserv [3]. Ho ..."

In this way we can simultaneously achieve high quality of service, high scalability and robustness. The key technique

Structuring Communication Software for Quality-of-Service Guarantees

by Ashish Mehra, Atri Indiresan, Kang G. Shin - IEEE Transactions on Software Engineering , 1996
"... In this paper, we propose architectural mechanisms for structuring host communication software to provide QoS guarantees. In particular, we present and evaluate a QoS-sensitive communication subsystem architecture for end hosts that provides real-time communication support for generic network hardwa ..."

This architecture provides services for managing communication resources for guaranteed-QoS (real-time) connections, such as admission control, traffic enforcement, buffer management, and CPU & link scheduling. The design of the architecture is based on three key goals: maintenance of QoS-guarantees

An Efficient Solution to Traffic Characterization of VBR Video in Quality-of-Service Networks

by Jörg Liebeherr, Dallas E. Wrege - ACM/Springer Multimedia Systems Journal, Vol , 1998
"... A network that offers deterministic, i.e., worst-case, quality-of-service (QoS) guarantees to variable-bit-rate (VBR) video must provide a resource reservation mechanism that allocates bandwidth, buffer space, and other resources for each video connection. Such a resource reservation scheme must be ..."

Dynamically Forecasting Network Performance Using the Network Weather Service

by Rich Wolski , 1998
