In static routing, an administrator will need to manually add the routes to networks in the routing table of routers (Forouzan 651). In a dynamic routing scenario however, algorithms and protocols are used for the automatic propagation of routing information to neighbour routers. In default routing, all the routers are configured to forward all packets to a single router. Because of the input of the network administrator in the static routing scenario, this configuration is not suitable for very large networks. Static routing is not also suitable for use in large networks. Dynamic routing would be advised to a ...

Communication System

The key elements of a data communication system are the source, the transmitter, the transmission system, the receiver and the destination. The source will be used in the generation of the data to be transmitted. The transmitter has a purpose of transforming and encoding the data into signals that can be transmittable for example the transformation from a digital bit stream to the corresponding analogue signal. The transmission system serves the purpose of carrying the data and it can be in terms of a transmission line or a complex network connecting the source and the destination. The receiver will ...

Question #1

The difference in depth is the use of multiple defense mechanisms in a layered format to protect internal systems, data, and users on a network infrastructure. The defense-in-depth strategy is required to use multiple defense systems that act in a fail-safe manner. The defense-in-depth strategy consists of security policies that protect both the business and employee information. The policies are a set of rules, compliance, and enforcement and provide authorization levels for various network activities. Some of the layers of a defense-in-depth strategy consist of authorization layer, ...

Executive Summary

A contemporary workplace without at least minimal tech infrastructure, such as PCs and laptops connected to a corporate Ethernet is hardly imaginable nowadays. At the same time, the practice demonstrates that the demands of technological modernity are continually evolving, and for many companies staying in line with the developments of technology is either organizationally impossible or financially unaffordable. Thus, statistically 44.59% of all global PC and laptop users still use Windows 7 and 7.65% have Windows XP installed, although Microsoft stopped maintaining the both operating system (VMWare, 2015). Because advanced operating systems require renewal of a corporate subscription and ...

Most Dangerous Thing for Dell to Extrapolate

Dell has for a long time used trend extrapolation in focusing on historical data on technological requirements since its inception for projecting future trends. If they will assume that the demand for their computers will continue like in the past. This assumption to quantify any change in performance of computing technology based on either straight line trend extrapolation, that is, on the continuation of the past behavior oblivious of whether there might have ever had some regular rate of change in the past of functional capability. It is probable this trend can only be sustained for a limited period ( ...

Routing Information Protocol version 2 (RIP v2) is a routing algorithm that is based on the Bellman-Ford algorithm. As a routing algorithm, it is used to determine the best path between two nodes on a network using distance-vector for path estimation. It makes use of hop count, which is the number of intermediate routers and gateways between a source node and a destination node, to estimate the best path with the maximum hop count put at 15 (Kalamani et al., 2014). This ensures that there are no routing loops in the network. The Bellman-Ford algorithm is based on dynamic ...

Routing Information Protocol version 2 (RIP v2) is a distance-vector routing algorithm that makes use of the hop count as metric for routing (Archana, 2015). The hop count is simply a path between a source and destination, which simply could be the number of intermediate routers, bridges or gateways between the source and the destination. A maximum of 15 hops is allowed in RIP v2, placing a limitation on the size of networks that can be supported by the protocol. The Bellman-Ford algorithm determines the shortest path to a destination using the principle of relaxation where the correct distance ...

Introduction

OPNET Modeler can be used in order to create and analyze network models; therefore, it can do organizational scaling to deal with a specific ‘what if’ problem. In addition, use of Project Editor is necessary in order to create a small network, gather and collect statistics about network effectiveness and performance, run a network simulation, and analyze the received results and statistics. Moreover, designing a new network can be made easier if a group of several scenarios is combined in order to explore different network aspects. In this lab report not only Loads and Delays on the first floor ...

Implementation of Authentication Process

The project described focuses on the deployment of WLAN in the school environment as the key aspect of technology application in the education sector both in the primary and secondary schools. The potential user users of WLAN, in this case, are the school non-teaching staff, teachers, and the students.

Probable WLAN Risks

Likely WLAN attacks can be grouped into the passive and active attack. The passive attack will consist of unauthorized access to the network assets with the purpose of traffic analysis. This kind of attack is always not easy to detect because the data remains unaffected and this make the emphasis ...
