The innovative application of 5G core technologies, namely Software Defined Networking (SDN) and Network Function Virtualization (NFV), can help reduce capital and operational expenditures in industrial networks. Nevertheless, SDN expands the attack surface of the communication infrastructure, thus necessitating the introduction of additional security mechanisms. A wind park is a good example of an...
Developing a virtualized network service does not only involve the implementation and configuration of the network functions it is composed of but also its integration and test with management solutions that will control the service in its production environment. These integration tasks require testbeds that offer the needed network function virtualization infrastructure (NFVI), like OpenStack, introducing...
The fault rate of on-load tap-changer (OLTC) has always been in a high level, and that is exactly the primary reason of transformer faults. As a result, an on-line detection method of OLTC was proposed. The embedded platform and wireless sensor network (WSN) technology was introduced into the on-line detection system. WSN was used to obtain OLTC status information. The embedded platform software,...
Network virtualization enables programmability to the substrate network provider who provisions and manages virtual networks (VNs) for service providers. A mix of software-defined and autonomic technology improves the flexibility of network management, including dynamic reconfiguration in the virtualized networking environment (VNE). Virtual router (VR)s run at a logical level where software failures...
Stream processing platforms allow applications to analyse incoming data continuously. Several use cases exist that make use of these capabilities, ranging from monitoring of physical infrastructures to pre selecting video surveillance feeds for human inspection. It is difficult to predict how much computing resources are needed for these stream processing platforms, because the volume and velocity...
In the process of aircraft development, we need to verify the Electrical Management System (UMS) on condition monitoring and control functions of each subsystem digitization, as well as the system management automation. For the subsystem power subsystem requires UMS achieve its AC and DC power supply subsystem bus bar, ground power, battery, rectifier unit and emergency DC generators and other equipment...
This paper proposes a network topology discovery algorithm and detailed implementation process. The paper introduces several kinds of centralized discovery technologies for network topology, and puts forwards a network topology discovery improvement algorithm. In the algorithm implementation, the authors independently design a software development kit (including encoding, decoding, network operation,...
The blasting spot monitoring is very important to reduce the occurrence of emergencies and to protect the workers' safety in practical applications. In this paper, we design an early warning system based on WSN (Wireless Sensor Network) which can be used in explosion operations. This system consists of two parts: the hardware part mainly uses several sensors to capture data we need and transmits them...
End to end testing is critical for ensuring the quality of a software product. Popular software products are deployed by customers in a wide variety of configurations over a broad range of hardware. Testing efforts, being subject to normal business constraints (limited time and resources) do not find it possible to recreate all customer scenarios in-house. In such a situation, it is valuable to understand...
Multi-Technology Operations System Interface (MTOSI) as an open interface has been proposed by TM-Forum in 2003. It not only supports the interactions between EMS-NMS like MTNM, also it generalizes the logic, and can be used for the communications between the other operations systems involved in the OSS. In this work, we first proposed the novel modular structured OSS functional architecture model...
Much of the GENI effort in developing network testbeds has been focused on building the control frameworks needed to allocate and initialize the network resources that make up an experiment. We argue that building the instrumentation and measurement system to monitor and capture the behavior of the network is just as important and challenging as setting up the network itself, especially in a virtualized...
Wireless Sensor Network (WSN) deployment appears like a crucial step for network Quality of Service (QoS). In this context a real conception has to be planed before a deployment on the studied area. Actually researches use a simple and regular Area of Deployment (AoD) representation and do not allow interactive interface for a non programmer. Our approach tries to provide a tool to elaborate a strategy...
This paper analyzed the status of networked manufacturing technologies, put forward new networked manufacturing mode based on the integration of ASP and CPC; constructed the overall framework for designing system under new networked manufacturing mode; integrated service and function from CPC based previous ASP networked manufacturing mode with deeply analysis about these service and topology structure,...
Software as a Service (SaaS) is a new software model for companies, which can provide them necessary software services based on a unique platform. In a general model of SaaS, the Independent Software Vendor (ISV) has a configurable and multi-tenant aware application. While in the actual working process, tenant always needs to do personal customization on different layers with individual requirements...
Architecture-centric system is analyzed by agent internetware, then the self-adaptive agent architecture is achieved. From belief, decision-making, intention point of view, it shows the flexible position of goal, which is the model statement level, and deepens some common description about the correlative environment and abnormity. The self-adaptive topology granularity unit of BDI and Agent is optimized,...
The interplanetary overlay network (ION) software at JPL is an implementation of delay/disruption tolerant networking (DTN) which has been proposed as an interplanetary protocol to support space communication. The JPL deep impact network (DINET) is a technology development experiment intended to increase the technical readiness of the JPL implemented ION suite. The DINET experiment operations center...
OPC(OLE for Process Control),which is application of Microsoft's OLE technology in process control system, provides a unified standard for the development in industrial automation software. The paper discusses the monitoring system base on OPC, in order to make system integration easier with advanced computer software technology, resolve the problem that transfer protocols are different between equipments...
We argue that there is a continuum between completely manual and completely automated management of networks and distributed applications. The ability to visualize the status of the network and applications inside a data center allows human users to rapidly asses the health of the system - quickly identifying problems that span across components and solving problems that challenge fully autonomic...
Based on the data samples authorized by CAIDA, we analyze the Internet router-level topology. By extracting several features of network property, we found obvious disparity distinction between the comparing results measured by single monitor point and multiple monitor points respectively, which approves that the sampling bias caused by single monitor point take primary effect on the Internet topology...
