Software Defined Networking (SDN) and Network Function Virtualization (NFV) are catching the attention of telecom operators. Telecom environments establish a set of Carrier Grade requirements such as high availability, high throughput and low latency. To address these challenges SDN deploys logically-centralized controllers, such as ONOS and OpenDayLight. Based on the JAIN SLEE component model, which...
Software-defined networks (SDN) are vulnerable to most of the attacks that traditional networks are vulnerable to. In addition, SDN has introduced new vulnerabilities through its unique architecture such as those related to the southbound and northbound controller interfaces. In this paper, we introduce a lightweight flow-based Intrusion Detection System (IDS) that periodically gathers statistical...
Information-Centric Networking (ICN) has emerged as an interesting approach to overcome many of the limitations of legacy IP-based networks. However, the drastic changes to legacy infrastructure required to realise an ICN have significantly hindered its adoption by network operators. As a result, alternative deployment strategies are investigated, with Software-Defined Networking (SDN) arising as...
Technological advancement of Industrial Control Systems (ICS) and control systems automation over the past decade has brought greater interconnections of the control components. Increased interconnection provides end users with more information which facilitates improved system reliability. Modern control communication systems such as ModbusTCP are based on open standards that leverage Ethernet to...
Software Defined Networking (SDN) is an approach developed to facilitate next generation computer networking by decoupling the traffic control system from the underlying traffic transmission system. One key focus in the transition of next-generation computer networking is the service management improvement of network connectivity services. Connectivity across the global digital network requires a...
This paper shall introduce the Taipei City Mass Rapid Transit underground section stations chiller Supervisory Control And Data Acquisition (SCADA) system and customized application software system development. Each station's existing chiller machine microprocessor Human Machine Interface (HMI) utilizes a standard communication protocol convertor and the environmental control system control room Open...
Connection setup in software-defined networks (SDN) requires considerable amounts of processing, communication, and memory resources. Attackers can target SDN controllers with simple attacks to cause denial of service. We proposed a defense mechanism based on a proof-of-work protocol. The key characteristics of this protocol, namely its one-way operation, its requirement for freshness in proofs of...
The main goal of this paper is to present a simple and inexpensive software solution for remote management of PTZ camera systems EVI-D70CP. Performed analysis demonstrates the technological solution for control of multiple cameras within lecture room or laboratory. Paper deals with the differences in the various serial communication methods, various functionalities of camera systems, followed by a...
Social networks and other clouding applications should require a fast response from datacenter's infrastructure. One of the techniques that has been widely used for achieving such requirements is the employment of In-Memory Key-Value Storage (IMKVS) as caching mechanisms in order to improve overall user experience. Memcached and Redis are applications that use IMKVS approach. Commonly IMKVS clients...
In this paper, we design and implement a scheme to build an optimal spanning tree over a hybrid network composed of SDN and legacy switches. SDN is an emerging network technology and gradually gaining adoption worldwide. However, during the technology transition period, which may last several years from now on, inevitably SDN switches and legacy switches will need to coexist in a network. In a legacy...
Software-Defined Networking (SDN) opens the configuring interfaces for the data plane to improve its flexibility[1]. In the data plane, the switches are partitioned into multiple domains. Each domain is dynamically configured by its controller. The domains are physically connected via the border switches. In the control plane, each controller supports multiple services. Each service runs the same...
With a quick glance through this paper the reader will question if it is being presented at the correct conference. The paper is full of IT jargon and networking concepts that would likely be more at home in an IT conference. That is exactly the point of the paper. Plant Control Systems are being tasked with handling increasing amounts of information from intelligent devices and subsystems in the...
In this paper, we describe our Java RMI inspired Object Request Broker architecture MicroRMI for use with networked embedded devices. MicroRMI relieves the software developer from the tedious and error- prone job of writing communication protocols for interacting with such embedded devices. MicroRMI supports easy integration of high-level application specific control logic with low-level device specific...
A high-resolution water display system(WDS) has been developed, which provides a new viewing modality for text/graphic information, unlike traditional display screens which use the brightness/color of built-in array of pixels on a flat panel to display information contents. The WDS has no fixed display screen which usese an array of water nozzles to precisely control the timing of water drops so that...
This paper introduces a distributed electronic monitoring system for the machine which is drilling the Sample of Deep-sea Core in deep ocean. The system composes of two components: monitoring and control computer on deck and underwater measurement and control system. Monitoring and control computer monitors and controls the underwater devices how to operator. Underwater measurement and control system...
The Human Machine Interface of engine monitoring system will be embedded in PC, the engine's running parameters could be acquisition, display and online adjustment in a real time by the serial communication. In this paper, an electronically controlled engine monitoring system has been designed by VB6.0, using the MSComm ActiveX of VB6.0 to achieve serial communication between PC and single-chip computer...
A bearingless permanent magnet synchronous motor (BPMSM) control system has a large number of control variables but has a small amount of data variables. So, adopting optimal coding scheme is demanded in its human-computer interaction. Based on the analysis of data format in serial port communication and data types of control variables, an optimal scheme of data split and combination and a coding...
