ADARM is a framework for application-driven and adaptive resource allocation to enable large scale service-oriented cloud DCs. It builds and utilizes real-time application profiles and models to understand application requirements and performance characteristics. In addition, service-orientation enables ADARM to use uniform and flexible REST services to abstract, organize, monitor and control the...
An Elastic Machine (EM) consists of networked fine-grained resources, such as CPU, memory, network and storage, dynamically composed from distributed resource pools offered by a RaaS (Resource-as-a-Service) cloud. EM allocation in RaaS clouds differs from VM placement in IaaS clouds in that it needs to consider the network conditions between the fine-grained resources. To address this problem, this...
SDN is an emerging networking paradigm that separates the network control plane from the data forwarding plane with the promise to dramatically improve network resource utilization, simplify network management, reduce operating costs, and promote innovation and evolution. While traffic engineering techniques have been widely exploited for ATM and IP/MPLS networks for performance optimization in the...
Applications in modern data centers have a wide variety of resource requirements along the four main dimensions of computing, memory, storage, and networking. Data centers must manage these resources separately for each dimension, resulting in highly inefficient allocation of precious resources or even disastrous schemes that contribute to low utilization or over-provisioning of resources. However,...
There are only three processors to manage thousands of airborne tasks with constraints in utility management system. Allocation of airborne tasks is an important problem. In order to solve the conflict between the huge number of tasks and limited computation resources, this paper proposes a task allocation strategy based on the heuristic constrained optimal tree algorithm (HCOT). Firstly, allocation...
To realize the potential benefits of SDN, tremendous amount of network information has to be collected, stored, processed and retrieved for the central routing and resource allocation optimization in near real-time. However, the current SDN-Open Flow controller and management applications did not address this issue properly and could not easily and efficiently retrieve and utilize the available analytics...
Network virtualization is a promising technology for the next generation network, which is required to offer a more dynamic and flexible network infrastructure. Virtual network embedding plays a vital role in the resource allocation of network virtualization. Current virtual network embedding allocates resources in an exclusive and excessive manner. For example, the whole bandwidth amount of the virtual...
Optical networks are ideal candidates for the future intra- and inter-data center networks, due to their merits of high throughput, low energy consumption, high reliability, and so on. Optical network virtualization is a key technology to realize the deployment of various types of network-based applications on a single optical network infrastructure. Current virtual optical network embedding allocates...
