“…To apply the IPSec safety protocol is one of the solutions to execute protection on community traffic, which provides verification and encryption to community packets, with the help of which community programs are secured. A crucial query that arises is that how the overhead of IPSec operations have an effect on the performance of community programs in the context of time-sensitive software, such as VoIP and comparable real-time packages [5]. In this research author describes that IPSec digital personal networks are drastically used to establish secure network connections between a pair of hosts, amongst a safety gateway or among a pair of protection gateways.…”

Online networks have many threats regarding security. The threats are targeting agency networks, private networks or other networks via gaining access to or changing essential information. Less secure networks deliver authorization to the users to access records in a network. Communication managers need powerful police forces to prevent access, misuse or alteration of secure network information. Small businesses or small businesses use firewalls, antibiotics or anti-spam software to protect the network, but do not provide sufficient network protection. Security in the corporate network is an important part of network protection due to the most common hacker goals. A private network is a reliable way of communicating with various business units and communicating with internal networks. Internet Protocol Security (IPsec) Virtual Private Network (VPN) is one of the most powerful security tools in the field of recording and security options. This is the safest and most secure option available in the Private Network store as a combination of two or more networks in remote areas. The goal of this research is to integrate VPN Services and establish IPsec protocols for small business security. The study is based on the networks of National College of business administration & economics (NCBA&E BWP) and its campuses by using the Cisco routers for a secure and private communication interchange between them. The result shows that IPsec VPN is an appropriate way of communication for Small and Medium-Sized Enterprises (SMEs).

“…2 The Erlang's formulas, aimed at the beginning to be used for performance calculation in public telephone networks, over the years have been applied in systems where the resources are limited, such as in mobile communication systems, VoIP (Voice over Internet Protocol) systems, computer networks, call centers, and electric vehicle power systems. [3][4][5][6][7][8][9][10][11][12] During planning and design of trunking and queuing systems and evaluating their performance, in addition to determining the probability of blocking and the probability of call waiting, which are the basis for estimating the quality of the service, it is also necessary to solve the inverse problem, that is, to determine the traffic intensity or the number of required channels (resources) for a given probability that corresponds to the desired GOS (Grade of Service) value. Given the nature of Erlang formulas, there is no inverse function of these formulas in a closed form.…”

In this article, a novel approach to calculate the Erlang B formula and its inverses is proposed. It is based on application of artificial neural networks (ANNs). Namely, ANNs are trained to calculate the Erlang B call blocking probability as well as to solve the inverse problem, i.e. to calculate the required number of channels or the maximum amount of traffic for the given call blocking probability. Comparing to direct calculation of Erlang B formula, computational efficiency is significantly increased, while the accuracy is maintained. As far as the calculation of Erlang B inverse values is considered, as there is a lack of exact mathematical formulas, the proposed approach provides the closed‐form mathematical expressions.
