Born Global Firms, Internet, and New Forms of Internationalization
2013
Although Internet is widely acknowledged to facilitate the rapid internationalization of born global firms (BGs), it is less known how such firms actually go about it. The current chapter specifically explores Internet-enabled internationalization (IEI) in the context of BGs. Based on e-adoption, international marketing and internationalization literatures, a conceptualization of IEI modes is suggested along three key dilemmas, assumed to underlie IEI mode configurations, including - functionality, localization and service directness. Three cases of Internet-enabled internationalizing born global firms (IEI BGs) from small open economies are then presented, as part of an effort towards conc…
The New Era of Business Digitization through the Implementation of 5G Technology in Romania
2021
The main objective of the present research is to identify the advantages and benefits that the use and implementation of 5G technology has on the development and evolution of the Romanian business environment. The study is based on a theoretical documentation regarding existing information in the field and a descriptive analysis of the evolution of the technology in Romania and worldwide. The research method chosen is a survey based on an opinion poll (questionnaire) to find out the availability of economic entities regarding the implementation of 5G technologies, the foreseen expectations and those realized by the business environment regarding the effects of 5G technologies on the economi…
Kyberturvallisuus esineiden internetissä
2017
Esineiden internetin laitteiden määrä on jatkuvasti kasvussa ja niiden hyödyt koskettavat kaikkia yhteiskuntamme jäseniä. Valitettavasti samanaikaisesti myös onnistuneiden kyberhyökkäysten määrä on kasvussa ja se uhkaa esineiden inter-netin luotettavuutta. Tämän takia onkin tärkeää tutkia, minkälaisia uhkia esinei-den internet kohtaa ja kuinka näiltä uhkilta voitaisiin suojautua. Tutkielmassa käsitellään esineiden internetin laitteita, mitä kyseiset laitteet ovat, kuinka ne toi-mivat ja miten ne ovat suojattu. Tutkielma toteutettiin kirjallisuuskatsauksena ja sen lähteinä on käytetty pääsääntöisesti akateemisten julkaisujen artikkeleita. Tutkielmassa selvisi esineiden internetin kyberturval…

Nanoseconds Timing System Based on IEEE 1588 FPGA Implementation
2019
Clock synchronization procedures are mandatory in most physical experiments where event fragments are readout by spatially dislocated sensors and must be glued together to reconstruct key parameters (e.g. energy, interaction vertex etc.) of the process under investigation. These distributed data readout topologies rely on an accurate time information available at the frontend, where raw data are acquired and tagged with a precise timestamp prior to data buffering and central data collecting. This makes the network complexity and latency, between frontend and backend electronics, negligible within upper bounds imposed by the frontend data buffer capability. The proposed research work describ…
SmartARP: merging IP and MAC addressing for low-cost gigabit Ethernet networks
1999
Abstract Address Resolution Protocol (ARP) is one of the key TCP/IP stack protocols, used on LANs to map 32 bit IP addresses into 48 bit hardware addresses. Regular ARP uses MAC layer broadcasts to perform the mapping. In this paper a new server-based ARP extension (smartARP) is proposed, which allows the extension of ARP functionality beyond a single MAC layer broadcast domain. Compared to regular IP router, smartARP together with simple broadcast-filtering switches presents a low-cost alternative for forwarding packets between MAC layer broadcast domains. SmartARP is transparent to existing IP hosts, operates independent of LAN speed, and scales for big networks.
Adding Real-Time Networking and QoS Capabilities to RTLinux-GPL
2006
This paper presents an architecture to build distributed embedded real-time systems in the RTLinux-GPL platform. The architecture (built in a layered fashion) has being built around open source projects ranging from Ethernet drivers to a CORBA environment. The paper focuses on those layers that give support for QoS and real-time networking over Ethernet networks. The main ideas are: to accomplish deterministic access times by using a TDMA protocol over Ethernet and to multiplex different types of traffic in that real-time network, providing different service types (QoS) to each type of traffic without jeopardizing the a priori guarantee of the system's real-time properties. Traffic types in…
The UJI industrial robotics telelaboratory: Real-time vision and networking
2008
In this video we present a work in progress in the UJI (i.e. the acronym for University Jaume I) robotics telelaboratory. This telelaboratory uses a remote control system based on networked robots and FPGAs technology. The main devices included in this cell are: a SCARA manipulator (AdeptOne), a robot arm with six degrees of freedom (Motoman), an industrial belt, several sensors and cameras, an FPGA that takes care of the computer vision algorithms (i.e. including grasping determination), and a distributed architecture that allows any user to control remotely via Internet a specific manufacturing task. The different components of this system are connected by a 100BaseT Ethernet network and …
A CORBA based architecture for distributed embedded systems using the RTLinux-GPL platform
2004
This paper describes an architecture for distributed computing on the RTLinux-GPL(GPL version of RTLinux, hereafter RTLinux) platform. The proposed architecture implements the CORBA (common object request broker architecture) model of computation, more specifically the minimum CORBA specification for embedded systems, and also provide the extensions for real-time computing. Since RTLinux lacks networking capabilities, the architecture implements all the required functionality in a layered fashion: network drivers, TCP/IP stack and an ORB (object request broker). Most of this work consists on a set of partings of some widely known open source Linux projects to RTLinux: Linux Ethernet device …
ZERO: An Efficient Ethernet-Over-IP Tunneling Protocol
2013
An Ethernet over IPv4 tunneling protocol is proposed, which categorizes all Ethernet frames to be tunneled into NICE and UGLY frames. The UGLY frames are tunneled by traditional methods, such as UDP or GRE encapsulation, resulting in substantial overhead due to additional headers and fragmentation usually required to transport long Ethernet frames over IP network typically limited to MTU=1,500 bytes. Meanwhile the NICE Ethernet frames are tunneled without any overhead as plain IPv4 packets due to non-traditional reuse of “fragment offset” or “identification” field in the IP header. It is shown that for typical Internet traffic transported over Ethernet, the proposed ZERO tunneling protocol …
