The article is devoted to the optimization of the structures and traffic development for information transmission in secured corporate networks by quantitative factor. Optimization is carried out in the local task of calculating rational amounts of information. To this end, a mathematical formulation of a local problem is formulated. Which is to optimize the resources of the information system by quantitative criteria. The task is solved by calculating rational amounts of information and entering them in the description of information system resources. It is necessary to evaluate the quality of networks that are being designed based on multicriteria optimization. This is due to the increase in volume and the variety of tasks being promoted to secured corporate networks. This optimization should take into account the full range of recent developments in the field of systematic approach, modern scalarisation principles, decomposition and aggregation techniques, graph theory, optimization algorithms, hierarchical synthesis structuring methods with consistent decision making. The task begins with the construction of information structures, which are linked oriented graphs. The vertices of the graphs are macro-level interaction tasks that carry out information exchange between local area network elements and local area networks, while arcs are information influences or messages. The structures for the micro level are accordingly constructed. Macro-level and micro-level interaction tasks are divided into three types: source resources; transit resources; user resources. The optimization of structures by quantitative factor is carried out in the local task of calculating rational amounts of information. The amount of information means the number of elementary characters. It should be noted that these are volumes of information that consist of basic rather than synthetic indicators. A reasonable amount of information must comply with the completeness of the information which are put forward by consumers task. If the amount of information is less than required, then the network element, the consumer, or the entire network will experience a lack of information. If the required volume is exceeded, there is an unproductive cost of generating, processing and transmitting information or the results of the tasks, as well as threats to the availability of the system. In the global case, the problem is much more complicated because part of the information flow can be an information destructive influence or a threat of breach of information security criteria.

AbstractManajemen jaringan di era jaringan komputer modern adalah hal yang sangat penting karena setiap perangkat dapat berkoneksi dengan perangkat lain yang berada di seluruh dunia melalui kecanggihan teknologi internet. Tentu saja dengan kemajuan ini membutuhkan suatu sistem pemantauan jaringan komputer yang membantu administrator jaringan dalam mengelola Local Area Network (LAN). Permasalahan yang sering timbul adalah kesulitan untuk mengetahui status open port disaat terjadi trouble ataupun serangan di dalam jaringan karena jumlah port jaringan mencapai 65.536, sehingga membutuhkan waktu yang lebih lama untuk melakukan perbaikan jaringan. Selain itu kebutuhan akan suatu sistem terintegrasi dalam pemantauan proses serta statistik port dalam Local Area Network (LAN) menjadi landasan dalam penelitian ini sehingga dapat meminimalisasi penggunaan sistem yang terlalu banyak dalam pemantauan jaringan komputer. Hasil dari penelitian ini adalah suatu sistem baru hasil modifikasi dari Mandau Registry Tools and Information System dengan menambahkan layanan seperti informasi protokol, statistik port, dan informasi tentang Domain Name System (DNS) dan penambahan layanan Access Control Lists (ACLs) dengan Fail2Ban. Menggunakan tahapan perencanaan, analisis, desain, implementasi, dan pengujian sebagai metode pengembangan sistem, diharapkan penelitian ini dapat membantu pemantauan dan keamanan Local Area Network (LAN) yang lebih baik dengan kompleksitas informasi proses jaringan dan statistik port yang dihasilkan.Lan memiliki kecepatan perpindahan data yang lebih tinggi Berfungsi. dengan baik tanpa adanya jalur telekomunikasi kelainan tidak membutuhkan akses internet.Local area network Lan merupakan sebuah komputer yang saling dihubungkan bersama di dalam satu area tertentu yang tidak begitu luas secara garis besar terdapat dua tipe jaringan atau lan bubar dan jaringan client server.Pada jaringan peer to peer setiap komputer yang terhubung ke jaringan dapat bertindak baik sebagai workstation maupun server. Sedangkan pada Jaringan client server hanya satu komputer yang bertugas sebagai server dan komputer lain berperan sebagai workstation.

“Urologist” was developed to run a Department of Urology. A local area network (LAN), one server and five stations, connects the single functional units of the Department (O.R.; I.C.U.; wards; Spinal Unit and Patient services). A Patient Identification Card integrates both clinical and organisational data. A multidisciplinary group, consisting of medical and non-medical specialists, was necessary to develop this system.

System Use

A local area network of six microcomputers provided 32 seventh-grade, LD and Chapter One students and their teachers with increased capabilities to access information associated with academic performance. Specific information in the system included descriptions of all academic tasks assigned to students, as well as such basic specifications as date due and point value. As each quarterly period of instruction within the school year progressed, the system accumulated a complete performance record for each student. Students, resource teachers, and mainstream teachers were able to request up-to-the-moment reports of pending assignments, missing work, grades on particular tasks, and estimated overall course grade. Findings obtained during a 27 week field test underscored the feasibility and potential significance of such a system. System use by students and teachers occurred at high levels. All participants indicated that system use was a positive experience and that system operation was important. A significant, positive correlation was obtained for student use and completion of academic tasks. Further potentials for such a computer-assisted information system are evident, including significant forms of home-school linkage and automatic recognition of student performance.

Traffic Network Design

In response to heavy demand for emergency logistics, an approach based on hierarchical network theory is introduced to solve the complexity of highway transportation network. It groups the traffic network into subprime networks and backbone networks on which a virtual local area network is designed accordingly to fulfill such function as information exchange and road condition renewal between forwarding stations. Compared with flat networks, the hierarchical traffic network design is in a good position to speed up routing, to conduct real-time monitoring and data-exchange, and consequently enhances efficiency of emergency logistics.
