In this paper, we propose a power-efficient solution for virtual machine placement and migration in a fat tree data center network. This solution reduces power consumption as well as job delay by aggregating virtual machines to a few hyper visors and migrating communicating parties to close locations. In this work, we consider OpenFlow as the implementation(More)
Recently, the requirement of shortened design cycles has led to rapid development of High Level Synthesis (HLS) tools that convert system level descriptions in a high level language into efficient hardware designs. Due to the high level of abstraction, HLS tools can easily provide multiple hardware designs from the same behavioral description. Therefore,(More)
While traditional security mechanisms rely on preventive controls and those are very limited in surviving malicious attacks, we propose a novel approach of the security issue to cluster recovery. In this paper, we present the cluster recovery model with a software rejuvenation methodology, which is applicable in security field. We propose two formal(More)
Due to consistent improvements in memory and processor technology, object storage devices (OSDs) have greater memory space and more powerful processing power, which allow the OSDs to execute user-defined programs. Shifting part of an application’s processing to the disk drives drops the amount of data transferred across the network and explores the(More)
Data Center Networks need densely interconnected topologies to provide high bandwidth for various cloud computing services. It is required to fully utilize the bandwidth resource in such a network with varying traffic patterns. We propose a flow-based edge-to-edge rerouting scheme for the Data Center Networks which has the mix of large flows and short(More)
The use of Software-Defined Networking (SDN) with OpenFlow-enabled switches in Data Centers has received much attention from researchers and industries. One of the major issues in OpenFlow switch is the limited size of the flow table resulting in evictions of flows from the flow table. From Data Center traffic characteristics, we observe that elephant flows(More)
Currently implemented Spanning Tree Protocol (STP) cannot meet the requirement of a data center due to its poor bandwidth utilization and lack of multipathing capability. In this paper, we propose a layer-2 multipathing solution, namely dynamic load balancing multipathing (DLBMP), for data center Ethernets. With DLBMP, traffic between two communication(More)
Enterprise cloud tenants would store their outsourced cloud data in encrypted form for data privacy and security. However, flexible data access functions such as data searching is usually sacrificed as a result. Thus, enterprise tenants demand secure data retrieval and computation solution from the cloud provider, which will allow them to utilize cloud(More)
