Cloud providers offer idle resources - Spot instances, in an auction-like mechanism. instances provide a dynamic and efficient manner for renting cloud resources. However, failures are often due to price fluctuations. Recently introduced variety of Block run uninterrupted predefined duration. In this paper, we propose model prices determination. Analysis different bidding strategies creating Blocks requests is provided. Two auction-based pricing mechanisms analyzed: Uniform auction...

This paper addresses interconnection contracts in content provisioning scheme with partial cloud migration. Model for traffic workload of such based on popularity factor is introduced. Monte Carlo simulation bandwidth demand estimation used. Cost analysis provider’s resources utilization regarding average requests’ rejection rate observed. The performance incentive migration applied. Three are analysed: Revenue Sharing, Sharing and Wholesale Price contract. Obtained results show that can...

The effects of dynamic traffic routing and interconnection charging methods on telecommunication network load balance are analyzed in this paper. results numerous simulations performed with software specially developed for analysis performances given. It is shown that adequately chosen method can give good balancing link loads which impacts the choice networks agreement. Ill. 7, bibl. 11 (in English; abstracts English Lithuanian).http://dx.doi.org/10.5755/j01.eee.108.2.142

In next generation networks, service providers should take into consideration not only quality of but also users’ experience aspects. this paper we propose Cournot game for modelling competition between two offering the same NGN to users classified according elasticity criterion. The proposed model includes parameters within utility functions and total demand as a function parameters. For have analyzed price setting through three distinctive cases. numerical results shown that providers’...

Forecast errors are always present in network design since they arise either from overestimation or underestimation of future load. Routing procedure can correct the forecast errors. In this paper capacity management model based on load and using dynamic routing for correction is presented. The results preplanned fixed procedures analyzed compared.

This paper proposes the Business-to-Business (B2B) model in field of railways, based on combining information integration and portal cloud computing technological environment. Information is carried out a common SQL Azure database. The enabled with Windows hosted service. proposed implemented case study systems that are used for railroad crossings management Serbian Railways.

This paper covers some important requirements for game theory based pricing of services in Next Generation Networks. We propose the Cournot modelling competition between two service providers offering same service. In this we analyze simulation results and found equilibrium price one special case proposed model.

Continuous forecast of bandwidth demand in order to achieve a proper network planning and dimensioning is one the key challenges that operators need deal with.The importance this issue highlighted with necessity decision making regarding capital investments permanent increase traffic volume.Under-investing resources lead low performances hence dissatisfied customers, while over-investing may cause over-dimensioned capacities which leads lower resource utilization opportunity losses.In...

Fractional calculus is a field of mathematical analysis concerned with research and application derivatives integrals an arbitrary order. Many famous mathematicians studied the theory fractional such as Euler, Riemann, Liouville, Abel, Fourier others. There are many proposed definitions for calculating non-integer In this paper, several along basic statements presented emphasis on possibility in telecommunication traffic modelling. The fact that widely used various scientific disciplines...

In distance learning, web-based software may provide an alternative to installation of expensive on the student computer, or laboratory equipment. This paper describes original e-learning software, which enables teaching and learning optical link design. Optical design is iterative process involving trade-offs achieve desired performance: bit error rate, transmission distance, etc., at minimal cost. Fundamental elements fiber are transmitter, with associated splices connectors, receiver. The...

In this paper some important requirements for game theory based pricing of services in Next generation networks are discussed. We propose the Cournot modelling economic interactions two service providers offering same and sharing network resources. The proposed model is verified through numerous numerical examples. we analyze results different total costs observed competitive providers. analyzed possibilities existence Nash equilibrium several such cases.

In this paper, results of extensive research concerning synergy dynamic routing and interconnection charging methods are presented. The impact various traffic on different performances interconnected telecommunications network with the application bill-and-keep is analysed. For purpose our research, we developed software for Routing Interconnection Simulation — RIS. Analysing obtained noticed that some methods, there several links completely unused. We introduce new load balance method in...

Telecommunication operators endeavour to offer their users numerous services and, at the same time, be competitive with other market while accomplishing high revenue. The only way achieve all those goals is make better usage of network resources and realise efficiency. In this paper, we tested assumption that a proper combination different dynamic telecommunication traffic routing methods interconnection charging can provide higher order analyze effects combinations four two on operator's...

Cloud computing is a widely used paradigm due to its substantial resource integration and capabilities.Cloud resources are organized into virtual machines (VMs) with corresponding computational storage capacities.Security pricing considered as important issues from both cloud provider customers' perspective, directly affecting the provider's revenues experience.VMs one of most vulnerable segments in environment.In this paper, VMs security modelling introduced assess level VMs.This approach...

This paper addresses cost issues in the process of content provisioning with partial cloud migration. Traffic workload is modelled depending on popularity factor. Bandwidth demand estimated using Monte Carlo simulation. Relevant parameter this analysis requests' rejection rate. Different pricing plans are observed. Hybrid plan as a compromising solution for costs' minimization and rate proposed.
