Efficient bandwidth resource allocation for low-delay multiuser video streaming

by Guan-ming Su, Student Member, Min Wu - IEEE Transactions on Circuits and Systems for Video Technology , 2005
"... Abstract—This paper studies efficient bandwidth resource allocation for streaming multiple MPEG-4 fine granularity scalability (FGS) video programs to multiple users. We begin with a simple single-user scenario and propose a rate-control algorithm that has low delay and achieves an excellent tradeof ..."

Optimal Streaming of Layered Video

by Despina Saparilla, Keith W. Ross - In Proceedings of Infocom , 2000
"... This paper presents a model and theory for streaming layered video. We model the bandwidth available to the streaming application as a stochastic process whose statistical characteristics are unknown a priori. The random bandwidth models short term variations due to congestion control (such as TCP-f ..."

as possible during playback. At any instant of time, starvation or partial starvation can occur at the client in either of the two layers. During periods of starvation, the client applies video error concealment to hide the loss. We study the dynamic allocation of the available bandwidth to the two layers

An Integrated Software Architecture for Bandwidth Adaptive Video Streaming

A Bandwidth Allocation Algorithm Based on Historical QoS Metric for Adaptive Video Streaming 1

by Ling Guo, Yuanchun Shi, Wei Duan
"... Abstract. This paper introduces a dynamic bandwidth allocation algorithm in a video streaming multicast system. The approach is to introduce the vibration of received video quality into the QoS metric and make the receivers more negative in subscribing higher layers when bandwidth increases. A simul ..."

Optimal Proxy Cache Allocation for Efficient Streaming Media Distribution

by Bing Wang, Subhabrata Sen, Micah Adler, Don Towsley - in Proc. IEEE INFOCOM , 2002
"... Abstract — In this paper, we address the problem of efficiently streaming a set of heterogeneous videos from a remote server through a proxy to multiple asynchronous clients so that they can experience playback with low startup delays. We develop a technique to analytically determine the optimal pro ..."

proxy prefix cache allocation to the videos that minimizes the aggregate network bandwidth cost. We integrate proxy caching with traditional serverbased reactive transmission schemes such as batching, patching and stream merging to develop a set of proxy-assisted delivery schemes. We quantitatively

DARD:DistributedAdaptiveRoutingfor DatacenterNetworks

by Xin Wu, Xiaowei Yang
"... Abstract—Datacenter networks typically have many paths connecting each host pair to achieve high bisection bandwidth for arbitrary communication patterns. Fully utilizing the bisection bandwidth may require flows between the same source and destination pair to take different paths. However, existing ..."
Abstract - Add to MetaCart
, existing routing protocols have little support for load-sensitive adaptive routing. We propose DARD, a Distributed Adaptive Routing architecture for Datacenter networks. DARD allows each end host to move traffic from overloaded paths to underloaded paths without central coordination. We use an Open

Bandwidth Allocation for Multiplexed VBR Video Streams with Deterministic Guarantees

by Marwan Krunz, Satish Tripathi , 1996
"... We present a new bandwidth allocation scheme for VBR MPEG-coded video. Compared to source-peak-rate allocation, this scheme achieves significant bandwidth gain while supporting stringent, deterministic QoS requirements. Video sources are modeled by time-varying envelops, and bandwidth is allocated a ..."

Optimal and suboptimal scheduling strategies for video sources are provided. 1 Introduction Efficient bandwidth

Optimal stream replication for video simulcasting

by Jiangchuan Liu, Bo Li, Senior Member, Ya-qin Zhang - IEEE Transactions on Multimedia , 2006
"... Abstract—Video simulcasting enables a sender to generate replicated streams of different rates, serving receivers of diverse access bandwidths. As replication introduces noticeable redun-dancy, balancing bandwidth consumption with user satisfaction becomes a critical concern in simulcasting. This pa ..."
