Abstract Quasi-period and chaos synchronizations of a laser local area network (LAN) are discussed deep by shifting or controlling the current parameters of one chain node lasers of the LAN. The two coupling-lasers as network’s double-driver nodes and other two laser as network’s receiver node lasers perform two chains of laser LAN. Multi-dynamics states and their synchronizations, such as quasi-period, chaos and their synchronizations, are guided to show in the LAN by varying the current parameters of one chain node lasers. We find that multi-dynamics state synchronizations, such double-period, period-3, period-4, period-5, other quasi-period and chaos synchronizations, are guided to present at two chains of the LAN. This LAN and its obtained results have import reference values for complex system, network, artificial intelligence, chaos synchronization.

Route To Chaos

Abstract Theory of chaos synchronization and quasi-period synchronization of an all optics local area network (O-LAN) is deeply studied and discussed, where two coupled-lasers are used as network’s double-star and the other single-lasers are used as network nodes. The LAN operates double-star lasers to drive node lasers in two links to perform a 2n−D (n is a positive integer, dimensions (D)) laser network. The O-LAN has the characteristics of an all optics LAN with double-center and two link nodes. Our theoretical and numerical results prove that the double-center lasers can obtain their synchronizations with each laser in two link nodes. A route to chaos after a quasi-period bifurcation is analyzed to illustrate dynamics distribution region of O-LAN. We find five quasi-period regions, four chaos regions, where there is a region where instability mixes with the first chaos, and a stable region. We find also that O-LAN can obtain its parallel multi-dynamics synchronizations, such as cycle-one synchronization, cycle-2 synchronization, cycle-3 synchronization, cycle-4 synchronization, cycle-5 synchronization, other quasi-period synchronization and chaos synchronization, shown in two links of O-LAN by shifting the currents of the lasers in one link. The theory of all optics LAN and its obtained results are useful to study on complex dynamic system, optics network, artificial intelligence, chaos and its synchronization.

This report focusses on the planning and realization of an interdisciplinary local area network (LAN) for medical research at the University of Heidelberg. After a detailed requirements analysis, several networks were evaluated by means of a test installation, and a cost-performance analysis was carried out. At present, the LAN connects 45 (IBM-compatible) PCs, several heterogeneous mainframes (IBM, DEC and Siemens) and provides access to the public X.25 network and to wide-area networks for research (EARN, BITNET). The network supports application software that is frequently needed in medical research (word processing, statistics, graphics, literature databases and services, etc.). Compliance with existing “official” (e.g., IEEE 802.3) and “de facto” standards (e.g., PostScript) was considered to be extremely important for the selection of both hardware and software. Customized programs were developed to improve access control, user interface and on-line help. Wide acceptance of the LAN was achieved through extensive education and maintenance facilities, e.g., teaching courses, customized manuals and a hotline service. Since requirements of clinical routine differ substantially from medical research needs, two separate networks (with a gateway in between) are proposed as a solution to optimally satisfy the users’ demands.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

This study aims to design a LAN network for data backup systems that are in accordance with certain aspects such as the selection of network design, network hardware, network transmission media, network connection devices, and network operating systems. Data is the most important thing for everyone, data can usually be reused even though it has not been used for some time, and therefore data storage is a serious problem that must be considered. Data on the server computer is very important to be maintained so that a backup process is needed on that data to another computer that is used as a backup in the event of damage to the hardware and software of the server computer. FTP is one of the solutions to the problems faced above,where FTP can be used to process the download and upload between the server and client computers. This design uses the Autobot system. The expected benefit in designing this LAN is that the existing network at SMP Negeri 6 Pekanbaru is not only used by employees and employees but can be used and enjoyed by teachers and students to access the internet anywhere as long as it is still within the scope of the SMP Negeri 6 area Pekanbaru.
