In this paper, we present the design strategies of a clientserver distributed multimedia presentation system that can flexibly support streaming continuous media data, in realtime, across Internet. In particular, we focus on the real-time buffer management and end-to-end data transmission. We present an effective and practical buffer management technique to address network delays and misorderin...

In this paper, we describe a RAT (radio access technology) agnostic approach referred to as OMMA (Opportunistic Multi-MAC Aggregation) that can aggregate multiple RATs operating over independent spectral bands. Aggregation and/or traffic shaping is performed above the air interface protocol stacks but below the IP layer. We investigate the problem of minimizing the average packet latency (the s...

Loss Differentiation Algorithms (LDA) are currently used to determine the cause of packet losses with an aim of improving TCP performance over wireless networks. In this work, we propose a cross-layer solution based on two LDA in order to classify the loss origin on an 802.11 link and then to react consequently. The first LDA scheme, acting at the MAC layer, allows differentiating losses due to...

The source of innovation is most often a matter of combining things in a new and unexpected way. To be able to do this, a cross-disciplinary understanding and ability to draw broader perspectives is underlined. This capability is underlined, as industries increasingly focus on developing end-to-end solutions. This also means that collaborative research projects will increasingly be such that th...

One of the major problems in networked multimedia is the playout synchronization of continuous media streams. The sink of a set of transmitted media streams has to reestablish the presentation timing of samples within each stream (intra-stream synchronization) and among streams (inter-stream synchronization). In applications that include live human-to-human conversation there is the additional ...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract The end-to-end principle is the core architectural guideline of the Internet. In this document, we briefly examine the development of the end-to-end principle as it has been applied to the Internet architecture over...

Within the North American freight railroad industry, there is currently an effort to enable more intelligent telemetry for freight trains. By enabling greater visibility of their rolling stock, including locomotives and railroad cars, railroad companies hope to improve their asset utilization, operational safety, and business profitability. Different communication and sensing technologies are b...
