SDN-Empowered Reliable and Dynamic Scheduling Scheme for Security Resources

By endowing network with the ability of reliable scheduling of security resources, it can realize the dynamic deployment of security resources as well as the efficient configuration of protection resources, and further can quickly respond to network security threats and emergencies timely. Furthermore, due to the network is increasingly complex, it is of great importance to make it reliable by invoking appropriate security resources. However, the security mechanism and response speed of traditional network based on security domain division, network boundary protection are hard to meet the requirements of the virtual network. In this paper, we propose the SDN-empowered reliable and dynamic scheduling scheme for security resources. In the scheme, we use network security resource virtualization technology to virtualize and modularize network security software and hardware resources; at the SDN control layer, we propose meta-security function combination technology to provide on-demand customization for various security applications’ security service; by using role-based conflict detection and conflict resolution technology, we can detect and handle security rule conflicts. The experiments show that the scheme is reliable and efficient with low latency and great throughput.

A Cloud Solution for Service Oriented Workshop Management

Cloud manufacturing is a state-of-art networked manufacturing model with the idea and technologies of cloud computing to transform traditional production-oriented manufacturing into service-oriented manufacturing. This emerging model can make manufacturing resources, in a manner similar to traditional utilities such as water, gas and electricity, available (offered) over the internet as convenient, scalable, on-demand services to enterprises. The aim is to improve the sharing efficiency of manufacturing resources and reduce manufacturing costs in industries. In this paper, the current research of cloud manufacturing is summarized, including relevant theories, technologies and applications. A cloud solution for workshop management is proposed from a service perspective, along with its architecture and business process. The methodologies, including manufacturing resource virtualization and workshop sensor network configuration are developed to support heterogeneous data integration and effective collaboration among services in cloud. A case study is demonstrated and discussed to validate the proposed cloud service system.

Using Ant Colony Algorithm on Scheduling Strategy Based on Docker Cloud Platform

With the development of Internet technology, the combination of industrial intelligence and data mining technology has played a huge role in the development of various industries, and has also become an inevitable demand for the development of information society. The cloud service can solve the problem of data processing conveniently and quickly, so it becomes particularly important for the development of cloud service. Traditional cloud service applications cannot meet users' urgent needs for services in terms of rapid release and efficient allocation of resources. Container technology has emerged to meet this challenge. Containers as a better resource virtualization technology will naturally be widely recognized and favored by the industry. Container cloud platform has the advantages of small redundant environment, high resource utilization, fast deployment, flexible and scalable. The proposed method use task scheduling of container cloud platform is to allocate available resources to users according to their different service demands. The result of this paper can ensure the effective execution of user container tasks.

Virtual Router Design and Modeling for Future Networks with QoS Guarantees

A virtual router model with a static and dynamic resource reconfiguration for future internet networking was developed. This technique allows us to create efficient virtual devices with optimal parameters (queue length, queue overflow management discipline, number of serving devices, mode of serving devices) to ensure the required level of quality of service (QoS). An analytical model of a network device with virtual routers is proposed. By means of the mentioned mathematical representation, it is possible to determine the main parameters of the virtual queue system, which are based on the first in, first out (FIFO) algorithm, in order to analyze the efficiency of network resources utilization, as well as to determine the parameters of QoS flows, for a given intensity of packets arrival at the input interface of the network element. In order to research the guaranteed level of QoS in future telecommunications networks, a simulation model of a packet router with resource virtualization was developed. This model will allow designers to choose the optimal parameters of network equipment for the organization of virtual routers, which, in contrast to the existing principle of service, will provide the necessary quality of service provision to end users in the future network. It is shown that the use of standard static network device virtualization technology is not able to fully provide a guaranteed level of QoS to all present flows in the network by the criterion of minimum delay. An approach for dynamic reconfiguration of network device resources for virtual routers has been proposed, which allows more flexible resource management at certain points in time depending on the input load. Based on the results of the study, it is shown that the dynamic virtualization of the network device provides a guaranteed level of QoS for all transmitted flows. Thus, the obtained results confirm the feasibility of using dynamic reconfiguration of network device resources to improve the quality of service for end users.
