We introduce a framework for provisioning end-to-end (E2E) managed video services over a multi-domain SDN, where different domains may be operated by different network providers. The proposed framework enables efficient dynamic management of network resources for network providers and ability to request the desired level of quality of experience (QoE) for end users. In the proposed fully-distributed...
This paper studies the SPLAY open-source framework that facilitates the design, deployment and testing of large-scale distributed applications. A mechanism for automatic control of a virtualized testbed created in OpenStack running Ubuntu 14.04.3 was implemented. The SPLAY entities involved herein were the following: a controller and a modified version of the daemons without using the sandboxing concept...
In today's era of communication, a company's brand is driven by more than the combination of promises made and promises kept for customer satisfaction to gain popularity of brand name. A telecommunications service provider's survival depends on its ability to prepare for changes in customer needs, as well as changes in regulation and technology. But the increasing expectations of customers and the...
Cloud Computing is a term which allows user to access the set applications to perform a group of functions or tasks on the internet enabled devices. The cloud has been divided into three types: private, public and hybrid which are briefly described in this paper. SaaS, IaaS and PaaS are the services of the cloud. Cloud is generally provided by the third party, thus it faces few security challenges...
Software-Defined Networking (SDN) is an emerging paradigm that arguably facilitates network innovation and simplifies network management. However, in the context of SDN, management activities, such as monitoring, visualization, and configuration can be considerably different from traditional networks. An SDN controller, for example, can be customized by network administrators according to their needs...
As an alternative to conventional batch chromatography as a discontinuous process, the simulated moving bed process (SMB process) as a continuous Chromatographie separation process gained more and more impact recently. For economically optimal operation of the process, a model based control and optimisation scheme is preferable. As part of this scheme, an one-line parameter and state estimation approach...
The IEC 61850 standard, using Ethernet as its primary communication architecture, can be utilized in a fashion to significantly benefit pulp and paper process users. While IEC 61850 defines three types of communication: Generic Object Oriented Substation Event (GOOSE), Manufacturing Message Specification (MMS), and Sampled Measured Values (SMV), this paper will focus on the benefits of Manufacturing...
A new type controlled switching device is introduced, which based on vacuum circuit-breaker (VCB) and power electronic switch(IGBT) to form the combination switch module. The structure and working principle of provided combination switch were emphatically expounded, especially the open and closing process and controlling strategy were discussed in detail. The researched VCB with permanent magnet actuator,...
The SLR is an important module in TS, which communicate with NMS, Message Engine, SAM, USC and ESM. In Media switch system, SLR is serviced as subscriber Installation, Authentication, Subscriber profile management, and Subscriber presence and location management for USC. In Media switch system, two or more SLRs are configured as a cluster environment to satisfy the requirements from USC and to improve...
FPGA has been used in many robotics projects for real-time image processing. It provides reliable systems with low execution time and simplified timing analysis. Many of these systems take a lot of time in development and testing phases. In some cases, it is not possible to test the system in real environments very often, due to accessibility, availability or cost problems. This paper is the result...
A new framework for designing evolved program execution control in distributed programs is discussed in the paper. The framework provides an infrastructure for designing distributed program control based on monitoring of global application states. Global control constructs are proposed which logically bind distributed program modules and define the flow of control dependent on the monitoring of global...
In order to solve capacity increasing of solar power system and the system's paralysis caused by the failure of host controller, a new controller was designed in this paper. Control system adopted two-level architecture which consisted of host controller and power modules. CAN bus technology was used for communication. It was easy to form solar power system of different capacities through combination...
There are many different factors that influence the safe production of coal mine such as equipment factor, environment factor and artificial factor etc. At current, many coal mines all over the world have built up harmoniously independent mutually monitoring and controlling sub-systems based on variety communicate channels and protocols. In this paper, a monitoring and controlling framework model...
We have already some technologies to perform these types of application such as: Bluetooth, IR. However these are used in a limited area which we can easily come over in the proposed system. This system has two sections one is Remote Section (RS) where the client will place the request and another is Local Section (LS) where the telephone line is connected with an Input Interfacing Circuit (IIC)....
Here introduces a monitor system technically based on ARM7 embedded micro processor (HMS30C7202) and Micro C/OS-II embedded operating system. The paper provides the scheme of the principal, introduces the connection method of outside signals, tells about how to transplant the Micro C/OS-II to the operating system, and shows the programming emphases and some source code of the majority of the program.
With the rapid advancement of Internet technologies, remote access of laboratory equipment and instrument via Internet is fast becoming a reality. This paper presents the implementation of a remote laboratory experiment for process engineering education. Based on configuration software and its extended application, we investigated five essential design issues: requirement specification, system architecture,...
Adopting the mechanism of transient working system, the article studies the brake and steady installment of the mine belt conveyor - the wheeled anti-lock hydraulic brake. Using the PLC, software and switch sensor, the installment can make the loose brake process safe and controllable, the supervisory system consisted of the speed sensor and PLC can make the brake control the band brake time automatically...
The security and trustworthiness of enterprise networks have been a major concern in the research and practice of Intranet security. The security of endpoints and their network access are inevitably two important factors regarding enterprise network security. In this paper we present a novel architecture to enforce controls on endpoint application execution and network access, in which the policy...
Based on the test-bed which had been built, a series of practical experiments have been carried out to study the impact of IEEE 802.1P on Real-time behavior of switched industrial Ethernet. Comparing the experimental results with the theoretical analysis, the differences between experiment and theory analysis were found. The experiments expose many problems when IEEE 802.1P is applied to the Switched...
According to the characteristics of many control points, requesting high stability and reliability about a temperature control system of baking barns for a preserved fruit production line, a temperature control scheme based on protocol macro is presented. This paper introduces the realization of the control scheme from system structure and communication programming in detail. The scheme improves the...
