Nowadays cloud computing services are being extensively used for server hosting, data storage, processing, computing, and scientific and research purposes. So data centers are the substrate of any type of services in cloud computing infrastructure. Virtualization technology provides the infrastructure of various virtual elements on similar substrate/physical infrastructure. Network virtualization...
Prior work by Pignolet et al. shows a new attacking methodology with which the attackers can disclose the whole cloud topology while deploying virtual networks in cloud, named "Topology Disclosure Attack". However, we discover some unreasonable attack assumptions in their model and this paper tries to develop a data structure, Query-Trie, providing topology disclosure attack a useful attack...
Infrastructure as a service (IaaS) has attracted significant attention from cloud research communities. While compute and storage resource management has been developed and studied to a greater extent, the use of network resource management in the context of IaaS is still in its early stages. There is a need for a comprehensive virtualization framework capable of providing users with low-level network...
Network virtualization is crucial in data centers environments for interconnecting all physical and virtualized resources to create a complete semblance of an integrated computing infrastructure. Much of the existing research on data center networking has focused on network mechanisms inside the datacenter. Little attention has been paid to networking mechanisms for integrating multiple data centers...
Workloads submitted to the Cloud are handled within the data centers in a distributed manner. Reducing the operational expenses is a fundamental concern for the operators which can be addressed by efficient design of the inter-data-center network. Optical networks have been reported to be the best transport media to accommodate the high capacity inter-data-center traffic. Furthermore, employment of...
Cloud computing has emerged to provide infrastructure for cost-effectively hosting applications with dynamically changing demands for computational resources. Dynamic resource allocation in cloud computing is made possible through virtualization technologies. In addition, live migration of services hosted in virtual machines (VMs) among multiple data centers is expected to add more flexibility in...
