We study the problem of predicting the performance of wormhole routed networks. A model of a single wormhole router is developed, and unlike previous methods we do the development by a probability analysis rather than queuing theory. The model is evaluated through a series of it level simulations. Then we indicate how our model can be extended to networks of routers, and argue that this extensi...

In this paper, we report some lessons learnt when deploying VoIP onto a small enterprise network. While these lessons resulted from a small network environment, some of the issues could have a more general applicability. Some theoretical analyses were first conducted, followed by some experimental work. An experiment was conducted for about 24 hours in order to capture the network measurement o...

is a model validated previously. In our study, only the average queue size k q − is considered, and the results are based on analytical model rather than actual measurements. The instabilities in the model are studied numerically using the conventional nonlinear bifurcation analysis. Extending from this bifurcation analysis, a modified RED algorithm is derived to prevent the observed bifurcatio...

Assured Service has been proposed within the Differentiated Services (DiffServ) model to provide relative service differentiation by attempting to allocate bandwidth to different users in a controlled way during periods of network congestion. In this paper, we analyze the Assured Service scheme by means of a priority queueing system with statedependent service scheduling based on thresholds. We...

Network calculus is a deterministic queuing theory that has gained increasing attention in recent time. Founded on min-plus algebra it resorts to intuitive convolution formulae for efficient concatenation of servers and derivation of related performance bounds. Yet, the pessimistic worst-case analysis of deterministic network calculus gave rise to probabilistic counterparts that aim at utilizin...

This paper offers a novel approach to the evaluation of provenance blockchain security and reliability using analytical methods for assessing system availability against malicious miner DoS attacks. In particular, we present analysis LightWeight Mining (LWM) protocol securing data provenance.

<span>Satellite communication is a telecommunications technique that uses satellites as connecting component, for example VSAT. In antenna installation, there an important process which called the cross-polarization. Cross-polarization one cannot be released inside installation of VSAT antennas satellite communication. Sometimes, in this process, user queue will occur. Queuing theory expl...

Many studies have indicated the importance of capturing scaling properties when modeling traffic loads; however, the influence of long-range dependence (LRD) and marginal statistics still remains on unsure footing. In this paper, we study these two issues by introducing a multiscale traffic model and a novel multiscale approach to queuing analysis. The multifractal wavelet model (MWM) is a mult...
