Block traces are widely used for system studies, model verifications, and design analyses in both industry and academia. While such traces include detailed block access patterns, existing trace-driven research unfortunately often fails to find true-north due to a lack of runtime contexts such as user idle periods and system delays, which are fundamentally linked to the characteristics of target storage...
This paper presents a multi-layer secure IoT network model based on blockchain technology. The model reduces the difficulty of actual deployment of the blockchain technology by dividing the Internet of Things into a multi-level de-centric network and adopting the technology of block chain technology at all levels of the network, with the high security and credibility assurance of the blockchain technology...
As The integration of Physical space and cyberspace, the large-scale data distributing to diversification terminal which is geographical distribution of mass has become a huge challenge. When the data size can't be processed by the technology for traditional scope, how to deal with the user quality of service and efficient use of system resources has become an important issue of concern, with the...
We present a data center service localization architecture based on virtual resource migration in software defined elastic optical network. The overall feasibility and efficiency of the proposed architecture are experimentally verified on our testbed.
Personal cloud storage is rapidly gaining popularity. A number of Internet service providers, such as Google and Baidu, entered this emerging market and developed a variety of cloud storage services. These ubiquitous services allow people to access personal files all over the world at anytime. With the prevalence of mobile Internet and rich media on web, more and more people use cloud storage for...
IP Multicast benefits data center networks (DCNs) for saving bandwidth and improving throughput. In-packet Bloom filter (BF) has been recently proposed to achieve efficient and scalable multicast in DCNs, where a Bloom filter encodes all nodes in a multicast tree into the packet header for making routing decisions. However, prior work incurs large traffic overhead due to tree encoding and false positive...
We present a cloud resources integrated provisioning architecture utilizing coordinated virtualization of distributed datacenters and operator's multi-domain software define optical network. The overall feasibility and efficiency of two proposed virtual network composition schemes are investigated on our testbed.
In the absence of legal authorities and enforcement mechanisms in open e-marketplaces, it is extremely challenging for a user to validate the quality of opinions (i.e. Ratings and reviews) of products or services provided by other users (referred as advisers). Rationally, advisers tend to be reluctant to share their truthful experience with others. In this paper, we propose an adaptive incentive mechanism,...
We demonstrate the disaster resilience of electric power applications for software defined disaster recovery center networking (SD-DRCN) based on elastic optical network. The overall feasibility and performances of the architecture are verified in our study.
Moving from dynamic lighptpath provisioning to virtual network provisioning, Optical as a Service (OaaS) is developing rapidly driven by data center application, which could be mainly enabled by Software Defined Networking (SDN).
Due to the high burstiness and high-bandwidth characteristics of the services, optical interconnect in intra-datacenter networks has attracted much attention. Many datacenter applications in the environment require lower delay and higher availability with the end-to-end guaranteed quality of service. In this paper, we propose a novel time-aware software defined networking (TaSDN) architecture for...
We present a multi-stratum resources integration architecture for data center application with flow estimation based on multiple OpenFlow controllers cooperation. The overall feasibility and efficiency of the proposed architecture are experimentally verified on our testbed.
We present a novel architecture for Cross Stratum Optimization of application and network resource with OpenFlow protocol. Several global load balancing strategies are proposed and demonstrated by experiments on Optical as a Service (OaaS) testbed.
The internet of things (IOT) has the same security requirements as traditional network, but according to the characteristics of its own, the internet of things also has some specific security features. Among these features, the flexibility of the network requires nodes to apply corresponding measures when scene changes. For example, in emergency situations (e.g. an accident occurs, and a doctor is...
Humanoid robot soccer platform based on global vision with distributed intelligence not only has the advantage of fast speed and highly ornamental value, but also has the distributed intelligence, combining the advantages of semi-autonomous and fully autonomous. System consists of two modules: the global vision module based on embedded system, the robot Autonomous decision-making module based on embedded...
Different from general multi-failure, group-failure in cross-layer intelligent optical networks has the characteristic of cluster. Because multi-failure may occur due to single failure, it is more harmful for multi-failure than single failure. The original survivability with regards to multiple single failures is not suitable for group-failure based cross-layer survivability research. Group-failure...
A dual routing engine-based routing scheme for large scale optical networks is proposed in this paper. An interpreter-based modeling of the group engine is discussed and a preliminary routing strategy is designed with consideration of scalability and flexibility.
Cloud computing, a new paradigm of distributed computing, introduces many new ideas, concepts, principals, technologies and architectural styles into enterprise service-oriented computing. The enterprise service-oriented architecture (ESOA) style is an abstraction of concrete enterprise service-orientated architectures, which includes SOA architectural elements, service design patterns as well as...
With the development of large-scale, multi-region and multi-layer networks, policy and constraint-based path computation is more and more complicated and dynamic routing becomes one of the key issues in GMPLS/ASON networks. Then a routing architecture named PCE is proposed to resolve the aforementioned complicated routing problem. However, as the huge bandwidth requirement emerges, capacity of Tbit/s...
On the basis of the analysis of the running pattern in the P2P file sharing system and the research of piece selection strategy in the BitTorrent system, presents a new piece selection strategy that records information of tables by using dynamic piece markers created. This strategy can keep the consistency of all pieces selection strategy by using rarest first strategy in the first piece selection...
