A fundamental requirement for any routing mechanism in network simulation is to truly reflect the forwarding process of packet from source to destination in the simulated topology. In current network simulators, all the nodes know the information instantaneously when the topology changed, which is obviously...

In the field of cloud manufacturing, in order to evaluate cloud service composition better, simulation could be introduced into the process of cloud service composition. This job requires adding simulation information to the service description document. Besides, for achieving the simulation of cloud...

In order to study the scale-free of more and more real-life networks, we design, construct a class of compound network models by the methods of graph theory for understand and try to simulate network models from Internet of Things (IoT), and we computed the parameters of models, such as: average degree,...

In multi-hop wireless ad hoc networks, communications with directional antennas can effectively improve the transmission range of the node. Most of existing directional routing protocols adopt the four-way handshaking mechanism which transmits and receives with directional and omnidirectional antennas...

With the continuous development of the Internet, the security problem of the Internet is more and more serious. The security postures of the Internet devices and applications have subjected extensive attention of the growing number of Internet users. In this paper, we put forward a measurement method...

With the development of smart grid, the data service of large particle and IP in power communication network has been increasing, which has put forward a great challenge to the existing power communication optical network based on MSTP (Multi-Service Transfer Platform) technology and WDM (Wavelength...

In this paper we describe a data network traverse algorithm. It traverses based on ternary tree and has Depth First Search (DFS) feature. The data network modeling employs three types of components: Line, Node and Intersection. Each type has typical data structure to connect other type. This algorithm...

Regarding the problem of lower utilization rate of broadband and data throughput in the real-time computations when Spark Streaming receiving and treating a large number of TCP packet, we proposed a technique of effective zero-copy of IO kernel and optimiazation of user protocol stack. By comparing and...

With the rapid development of the Internet economy, people's consumption level is getting higher and higher, the demand for customized services is becoming increasingly apparent. At the same time double O2O mode shine in the Internet Age. Based on the field investigation in Wuhan, this paper studies...

Nowadays, massive databases have accumulated and networked in the large-scale and distributed networks, however, in which extensive data are still hard to be directly shared to or efficiently exploited by the users as many challenges and technical designs of query processing are arising in the networks....

Network attack becomes more popular today. It is still difficult to detect the intrusion activity accurately for users websites through traditional approaches. A kind of integrated system is designed and established for the website security analysis based on Hadoop system. The core components of hardware...

Software-defined networking (SDN) is an emerging network architecture, which decouples the control and data planes of a network. Owing to its openness and standardization, SDN enables researchers to design and implement new innovative network functions and protocols in a much simpler and flexible way....

The diameter of hypercube and its properties is an important issue for improving thecommunication efficiency of interconnection network. A new variant SQ _n^k of the n-dimensional hypercube is introduced by a spinningfunction _k. In this variant, called k-spined cubes, neighbors of any node can be quickly...

Free blocks and free pages have tremendous forensic potential. Based on analyzing layouts of cells which have different types of keys, the mechanism of deletion and free blocks coalescing, a new recovering method with byte level accuracy is proposed. First, aiming at multiple keys' types and rewriting...

Content Centric Networking (CCN) is a new network architecture around content dissemination and retrieval, which treats content as a primitive and routes content by name. Differently from the conventional content dissemination and retrieval of the CCN, we introduce a novel content delivery scheme based...

Hypertext is the main format on the Internet, which has the characteristic of the non-continuity and simple formal standard. This paper researches how to extract information from hypertext by regular expression, gives the example on extracting weather information base on the web of Sohu, Sina and Tencent...

Software-Defined Networking (SDN) is a new paradigm that offers services and applications great power to manage network. Based on the consideration that the entire network visibility is the foundation of SDN, many attacks emerge in poisoning the network visibility, leading to severe host hijacking. Meanwhile,...
