In current virtualized cloud platforms, resource provisioning strategy is still a big challenge. Provisioning will gain low resource utilization based on peak workload, and provisioning based on average work loads will sacrifice the potential revenue of cloud customers because of bad user experiences. VM-based performance isolation also restrains resource flowing on demand. As to memory, this eventually...
Cloud computing is a new emerging computing paradigm that advocates supplying users everything as a service. Compared with grid computing, the focus of resource management problem is transformed to resource virtualization and allocation rather than job decomposition and scheduling. It is more urgent to find better solutions for cloud resource allocation than ever before. Although there have been some...
A computational is a wide-area computing environment for cross-domain resource sharing and service integration. Most clouds generally emphasize sharing resources and services on demand, the scheduling strategy based on selecting resource that are near and owns more bandwidth available has better characteristics. The notion of game theory is proposed in this paper, which can be used as the criteria...
The future Internet is envisioned to host a large number of virtual networks managed by different operators sharing the same physical infrastructure. In such a scenario, an operator may not even own physical resources as such, but lease virtual resources to have their own virtual networks. While control-plane virtualization with several routing instances becomes common in equipments, the data plane...
Programmable packet processors have replaced traditional fixed-function custom logic in the data path of routers. Programmability of these systems allows the introduction of new packet processing functions, which is essential for today's Internet as well as for next-generation network architectures. Software development for many existing implementations of these network processors requires a deep...
A new methodology of mobile police spatial information service grid model is studied based on spatial grid computing environment. Key technologies are presented in the model, including spatial grid computing, mobile agent (MA) distributed computing, mobile geographic information system (GIS), global positioning system (GPS), video monitoring, transfer control protocol/internet protocol (TCP/IP), and...
The future Internet is driven by applications that require simultaneous access to multiple heterogeneous IT resources interconnected by high-speed optical network. Current research on network and IT resource co-allocation address advanced reservations in which each resource-type is optimised independently. However, emerging applications demand a resource co-allocation model that views and optimizes...
China's networks and railways develop rapidly, which urgently requires mobile Internet access. However there exist challenges on network integration of access schemes, on network applications of the transition period, on high cost of all-coverage access, on high bit error rate, on frequent interruption, and on traffic explosion. The proposed multi-homing hierarchy DTN-based train mobile Internet access...
With the development of broadband wireless networks and increasing demand of multimedia information on internet, the study of video streaming transmission has become a hot topic in nowadays. Through analysis three main points of streaming media transmission, and by combining the forthcoming H.264 Scalable Video Coding and Congestion Control algorithm based on accumulated mechanism, this paper presents...
In an open distributed system, computations can be carried out without statically owned resources, harnessing the collective compute power of the resources connected by the Internet. However, realizing this potential requires efficient and scalable resource discovery, coordination and control, which present challenges in a dynamic, open environment. We present ROTA, a resource-oriented temporal logic,...
General sharing of information resources on the Internet has already be achieved through Internet technology. But the goal of grid is trying to achieve a comprehensive connectivity and sharing for all resources on the Internet, providing high-performance computing services for users. In this paper, grid resource scheduling was studied and according to the current research about it some innovation...
This paper proposes a new paradigm and strategy for resource management in optical networks considering that resources allocated to a user or service can be squatted in by third parties temporarily in order to provide support for emergency situations or allocate traffic from different priorities that experience a sudden increase of demanded resources in the network. We introduce the strategies of...
In this paper an optimal allocation approach of virtual servers to appropriate data centers is proposed for a network made up of collections of data centers and user groups. The virtual server allocation can be formalized as a linear programming (LP) problem which consists in minimizing the round-trip-times (latencies) between data centers and user groups. Our proposed allocation approach demonstrated...
The following topics are dealt with: data center; Internet networking; location sensing; RFID; clouds; grids; data streaming; querying; IP networks; system security; data management; network security; sensor networks; fault tolerance; routing; social networks; resource allocation; network coding; P2P; and wireless networks.
To allocate cloud resources efficiently and obtain the maximum economic benefit are the major goals of the cloud resource providers and users. The objective of this paper is to present a novel cloud resource allocation algorithm named NECDA to overcome some of the shortcomings of the current mechanisms. A cloud resource allocation model of m*n type based on M/M/1 queuing system is established first...
Although significant efforts have been devoted in the literature to measurements of the Internet topology, little attention has been given to the qualification of routing deviations and multipath dynamics at the Autonomous System (AS) routing level. We observed Internet AS-level routes toward thousands of destinations for several weeks between 2009 and 2010 to have a better understanding of these...
This paper proposes a collaborative transit system architecture based on multi-agent-mechanism, in which employed are such different of Agents as Order Agent, Management Agent, Task Agent, SAgent and TUAgent. Also, it introduces the respective function of these Agents. Furthermore, according to the announce and bid processes in the contract net protocol,this paper give out the schedule flow based...
Virtual machine technology enables agile system deployments in which software components can be cheaply moved, replicated, and allocated hardware resources in a controlled fashion. This paper examines how these facilities can be used to provide enhanced solutions to the classic problem of ensuring high availability while maintaining performance. By regenerating software components to restore the redundancy...
Cloud computing is fundamentally altering the expectations for how and when computing, storage and networking resources should be allocated, managed and consumed. End-users are increasingly sensitive to the latency of services they consume. Service Developers want the Service Providers to ensure or provide the capability to dynamically allocate and manage resources in response to changing demand patterns...
