A substantial number of massive large-scale applications require scalable underlying network topologies. Nowadays structured Peer-to-Peer overlay networks meet these requirements very well. But there is still a need to decide which of these overlay networks is most suitable for providing the best possible performance for a certain application. This paper describes SimCon a simulation environmen...

In this work, we propose a configurable many-core overlay for high-performance embedded computing. The size of internal memory, supported operations and number of ports can be configured independently for each core of the overlay. The overlay was evaluated with matrix multiplication, LU decomposition and Fast-Fourier Transform (FFT) on a ZYNQ-7020 FPGA platform. The results show that using a sy...

Internet overlay services must adapt to the substrate network topology and link properties to achieve high performance. A common overlay structure management layer is desirable for enhancing the architectural modularity of service design and deployment. For instance, new link probing techniques can be incorporated into the common structure layer such that a large number of overlay services can ...

A foundational issue underlying many overlay network applications ranging from routing to peer-to-peer file sharing is that of the network formation, i.e., folding new arrivals into an existing overlay, and rewiring to cope with changing network conditions. A typical overlay network for routing or content sharing, each node must select a fixed number of immediate overlay neighbors for routing t...

This paper explores the model of providing a common overlay structure management layer to assist the construction of large-scale wide-area Internet services. To this end, we propose Saxons, a distributed software layer that dynamically maintains a selected set of overlay links for a group of nodes. Saxons maintains high-quality overlay structures with three performance objectives: low path late...

We study a class of models, known as overlay optimization problems, with a "base" subproblem and an "overlay" subproblem, linked by the requirement that the overlay solution be contained in the base solution. In some telecommunication settings, a feasible base solution is a spanning tree and the overlay solution is an embedded Steiner tree (or an embedded path). For the general overlay optimiza...

in order to evaluate the effects of methanol on germination percentage, germination speed index, plumule and radicle length, plumule and radicle dry weigh, vigor index and consumed endosperm of bean in condition of water deficit, a factorial experiment done based on completely randomized design with three replications. the first factor was different levels of methanol included 0 (control), 5, 1...

Overlay networks have emerged as a fundamental technique for efficient data dissemination. Current overlay construction techniques typically face a number of limitations, including: i) limited scalability because of reliance upon global knowledge, and ii) performance characteristics targeting the requirements of a particular class of applications. In this paper, we propose dynamically organizin...

Due to the growing demand for high definition music and video content, an overlay multicasting providing live streaming services has been gaining popularity over last years. In this paper, we focus on applying the overlay multicasting for delivering of critical data that require to be transmitted safely, intact and with as little delay as possible, e.g., financial data, software security patche...
