Erasure resilient FEC codes in off-line packetized streaming rely on time diversity. This requires unrestricted buffering time at the receiver. In real-time streaming the playback buffering time must be very short. Path diversity is an orthogonal strategy. ...
We propose a method for fine grain QoS control of real-time applications. The method allows adapting the overall system behavior by adequately setting the quality level parameters of its actions. The objective of the control policy is to meet QoS requireme ...
In this paper, we present five case studies of advanced networking functions and how a network processor (NP) can provide high-performance and exible support for each of them. We first review the basic NP system architectures, and describe in more detail t ...
We propose a novel approach to the composition of group communication protocols. In this approach, components are modelled as finite state machines communicating via signals. We introduce two building blocks, called adaptor and adaplexor, that ease the dev ...
Group communication provides primitives that ensure reliable and ordered delivery of messages to a group of destinations. It is an important building block for replicated fault-tolerant applications such as replicated databases. In the past, most group com ...
A scalable feedback mechanism to solicit feedback from a potentially very large group of networked nodes is an important building block for many network protocols. Multicast transport protocols use it for negative acknowledgements and for delay and packet ...
We propose to represent the "basic behaviors" of MPEG-7 description tools as a set of constructor, operator and function signatures. This way of making explicit the behavior of datatypes using function signatures is commonly used to formalize data models.A ...
As a component of the intelligent transportation system (ITS) and one of the concrete applications of mobile ad hoc networks, inter-vehicle communication (IVC) has attracted research attention from both the academia and industry of, notably, US, EU, and Ja ...
Chimeric users have recently been proposed in the field of biometric person authentication as a way to overcome the problem of lack of real multimodal biometric databases as well as an important privacy issue -- the fact that too many biometric modalities ...
The recent development of real-time measurements and control tools in JET has enhanced the reliability and reproducibility of the relevant ITER scenarios. Diagnostics such as charge exchange, interfero-polarimetry, electron cyclotron emission have been upg ...
