The cloud computing as a ubiquitous paradigm could provide different services for internet users and Information Technology (IT) companies through datacenters located around the world. However, cloud provider faces several problems such as security and privacy issues in cloud datacenters. Hence, cloud provider has to handle security challenges to gain more profit. In this paper, a SecurityAware...

We propose a novel Optical Network Units (ONU) migration mechanism within the Time and Wavelength Division Multiplexed PON (TWDM-PON) framework by rearranging the working ONUs to a minimum number of wavelengths and turning off the rest to save power. We show through simulation that the number of working wavelengths can be minimized up to a theoretical lower bound, e.g. 23%, under the typical ON...

Unwanted traffic injection which amplifies the traffic loading and exhausts network resources is counted as network security threat. Despite of the numerous protection systems, this threat is still lacking powerful remedy till day. This paper proposes a potent model for unwanted traffic detection in edge-to-edge QoS network domain. It is designed to detect service violations and bandwidth theft...

Cloud Computing is an emerging technology in today’s world. Many of the IT companies and some of the government and non government organizations are using this technology. This technology plays a crucial role which can be accessed over a network channel i.e.., Internet. This paper aims to implement a probabilistic model for performance analysis in different services of cloud computing technolog...

The ongoing aim behind the work described here is to investigate support for a data centre type environment where an application can be implemented as a composition of components, or workflow. For instance, an application might reuse established components. As is typical in data centre operation, hosting of an application is governed by a Service Level Agreement (SLA) between provider and appli...

Since participants in a Cloud may be independent bodies, some mechanisms are necessary for resolving the different preferences to establish a service-level agreement (SLA) for Cloud service reservations. Whereas there are some mechanisms for supporting SLA negotiation, there is little or no negotiation support involving price, time slot, and QoS issues concurrently for a Cloud service reservati...

While the backbone networks have experienced substantial changes in the last decade; the access networks have not changed much. Recently, passive optical networks (PONs) seem to be ready for commercial deployment in access networks due to the maturity of a number of enabling technologies. long distance and reduced maintenance. Among PON technologies, the Ethernet PON (EPON) presently being stan...

Cloud service providers mostly offer service level agreements (SLAs) in descriptive format which is not directly consumable by a machine or a system. Manual management of SLAs with growing usage of cloud services can be a challenging, erroneous and tedious task especially for the cloud service users (CSUs) acquiring multiple cloud services. The necessity of automating the complete SLA life cycl...

This paper analyses Q1 the relationships Q2 between different service level agreement (SLA) components, that is, the different types of quality metrics employed by infrastructure and service providers. We propose that the quality of network economics (QoNE) be used to evaluate the quality of a network path for a given SLA model. Our evaluation indicates the usefulness of the QoNE metric, and it...
