Virtual Private Network Implementation with GRE Tunnels and EIGRP Protocol

Nowadays, the modern companies and institutions have a inevitable need for secure connections with remote locations trough broadband WAN networks. The reason for such requisite is mainly the need for shared services utilization like application servers, database servers, messaging servers, etc., physically located at remote datacenters. In this paper, we present realistic VPN implementation and configuration for a company with two central locations (head office and warehouse) and branch offices in several cities. For secure communication between central locations and branch offices, Generic Routing Encapsulation (GRE) tunnels are implemented. EIGRP protocol is used for routing the data between networks. From the implementation analyses conducted in this paper, we can figure out that this approach allows low-complexity realization and low-cost maintenance solution

Modeling and Implementation of Bus Rapid Transit corridor based on isolated or coordinated Traffic Prioritization and Automatic Location

In many cities facts defining conditions for very high concentration of functions and population make transport difficult. The proposed solutions are Automated Vehicle Location (AVL) and prioritization systems for mass urban transport buses, and priority vehicles, through a Bus Rapid Transit (BRT) corridor. Two solutions presented, which consist of a detection sub-system, with a bus component, using transmitter, and a receiver placed on the traffic lights, in the case of isolated system and an additional control center, in the case of the integrated / coordinated system. The functionality is described, and it is also presented as architecture the solution of an integrated bus priority management GPS system. In both cases we aim in minimizing the waiting time on traffic lights, and thus the waste of time on traveling. Such system is a useful instrument for any mass urban transport system

Analysis of digital marketing and branding for the purpose of understanding the consumers in digital age

The changes have brought us a new age – “the digital age” and this age has brought us some new challenges that seek to solve the problems of organization in a new way. The digital age, as far as branding is concerned, has brought many advantages to the organization and it can be an extremely valuable marketing tool, but only if the organization manages to gain a positive relationship between the brand and consumers and if it has a proportional advantage in comparison to its opponents; because, on the other hand, besides all advantages it brings us, the digital age can set up many traps. This paper is about the current situation in the global market and pays our attention to some segments of business which are important in digital age for subsistence and the success of an organization. It presents the current awareness of consumers and their way of thinking and acting. The purpose of this paper is to point out conceptual frameworks of branding in Internet form, to show how those frameworks can help marketing planners by organizing and integrating the existing knowledge in development of successful strategies of branding on the Internet. A real example of one of the leading global brands that succeeded to win the challenges of the digital age will be presented in this paper

The most suitable organizations that\ud implement the knowledge management core concepts are universities. In this paper the main focus is to represent a model framework for the structure of the university\ud knowledge management system and to give an overview for the design of prototype expert system for evaluating university teaching activities tо enhance the university performance and decision making process

Informatization as a Measure for Improvement of the Education Policy – Case Study: Electronic Content Portal

The intensive development of information technology in the new millennium has redesigned the functioning views, rules and principles of educational organizations. They have been set to the challenge of how and in which way information technologies influence the improvement of the effectiveness of the educational surrounding. As a result of this process, the overall improvement of the education system, analyzed as a whole, as well as its compliance with modern trends and needs, inevitably leads to the necessity of improving the process by applying information technologies. The extent by which a geographical area, an economy or a society is becoming information-base, increase in size of its information labor force, is referred to as informatization, whereas the principles and government policy-making in educational sphere, as well as the collection of laws and rules that govern the operation of education systems is an education policy. In this paper, the need of creation of educational policy by using information technology is examined, with particular reference to one of the measures for improvement of the education policy, such as an online resource (www.skoool.mk), as a case study, on the bases of which appropriate conclusions and recommendations are drawn

Implementation of embedded assistive device for disabled people

In this paper we present an embedded assistive device for disabled people that is intended to be used as both keyboard and mouse replacement. Assistive device consists of two main parts: an Arduino compatible board, preferably an Arduino UNO R3 as used in this paper, or an Arduino Leonardo, and a simple analog thumb-stick joystick. Presented device is connected to a computer trough a USB port trough which it sends its input data. Special software\ud collects the received input data and triggers various events in order to execute various actions. Primary goal of presented assistive device is to simulate mouse movements and a single mouse click and in that manner replace majority of moue functions thus enabling users to perform various mouse based tasks such as navigating through menus, drag and drop actions etc., as well as to enable an input and control over a virtual onscreen keyboard thus enabling users to type

Agile Management of IT Projects by Modified Scrum Processes

Scrum is the result of evolution in product development originating from the Japanese management system and process improvement (kaizen) and the Toyota production system from middle of the 20th century. However, Scrum is not the end result but a constant evolution. The purpose of this paper is an attempt to add new knowledge to this evolution. There are numerous alternatives to Scrum process and rules, commonly called hybrids. It is important to be aware that one approach or process cannot be a solution for every software development project. The key is to find a balance between the processes and the people, policies and the principles, as well as focus on long-term or short-term goals, etc. This problem is one of the biggest challenges widely discussed in present-day scientific and industrial communities

Behavioural – based modelling and analysis of Navigation\ud Patterns across Information Networks

Navigation behaviour can be considered as one of the most crucial\ud aspects of user behaviour in an electronic commerce environment, which is very\ud good indicator of user’s interests either in the process of browsing or purchasing.\ud Revealing user navigation patterns is very helpful in finding out a way for\ud increasing sale, turning the most browsers into buyers, keeping costumer’s\ud attention, loyalty, adjusting and improving the interface in order to boost the user\ud experience and interaction with the system. In this regard, this research has\ud identified the most common user navigation patterns across information networks,\ud illustrated through the example of an electronic bookstore. A behavioural-based\ud model that provides profound knowledge about the processes of navigation is\ud proposed, specifically examined for different types of users, automatically\ud identified and clustered into two clusters according to their navigational\ud behaviour. The developed model is based on stochastic modelling using the\ud concept of Generalized Stochastic Petri Nets which complex solution relies on\ud Continuous Time Markov Chain. As a result, calculation of several performance\ud measures is performed, such as: expected time spent in a transient tangible\ud marking, cumulative sojourn time spent in a transient tangible marking, total\ud number of visits in a transient tangible marking etc
