Introduction
Packet Tracer is a very powerful simulation tool from Cisco Systems, used to
Educate students on Network environment simulation. Created by Cisco Systems; as
part of the Networking Academy, it allows students to create network environments, for
practicing different networking situations. Packet Tracer provides simulation,
visualization, authoring, assessment, and collaboration capabilities and facilitates the
teaching and learning of complex technology concepts. (Cisco Networking Academy, 2014)
Cisco Systems created Packet Tracer so people interested in becoming Cisco Certified
Network Associates could practice, learn and get the CCNA certification. The tool was
made for practice ,and learning only; and it cannot compare to the real Cisco Switches
and Routers on real enviroment. Packet Tracer can be utilize for simulation with the
different kinds of protocols, devices, and troubleshooting tools to diagnose, check and
connect Networks made by the student in the platform to check connectivity.

At the beginning of the Glo Bus simulation our team developed a strategy that would allow us to compete with the other seven teams and put us in a position to gain a competitive edge. During the first few phases we were able to give a strong showing, however as the game progressed it was clear that other teams were implementing a similar strategy and making headway into our space. Reacting to the market changes was showing negative effects on our growth so we developed a new strategy to set us apart and allow our company to compete.
In recent years there has been a growing trend involving the use of closed circuit
Security of the companies data is one of the most important components which allows the business to perform its day to day operation using various networking devices, services that absolutely needs to be protected from intruders. Some of these devices include online transactions, the exchange of data between users and clients both internal and external and external web data needs to be secured. There are several polices that would need to be configured such as a web sever and firewall configurations. However, with these configurations the first and most important task is to identify any vulnerabilities or loopholes in security within the company. The company has both LAN (Local Area Network) and WAN (Wireless Local Area Network) and a web sever. These resources need to be secured at all times from hackers or anyone else by implementing the appropriate security measures.
On the other hand, Gregory Mantsios’ point of view on the “effects on Family” that over the years, the upper-class who have more of an advantage due to better education, healthcare coverage and are fundamentally more well balanced have a better chance at getting married which gives them better family activities because they have financial acumen (Mantsios290). The wealthier you are, the more opportunities your family is given. Mr. Mantsios list four myths in his article that are relative to the “effects on family” which are: 1. “Rich or poor, we are all equal in the eyes of the law, and such basic needs as health care and education are provided to all regardless of economic standing.” 2. “We are, essentially, a middle- class nation. Despite
In this essay, I will argue that the Trillium Gift of Life Network was not ethically permitted to deny Delilah Saunders a liver transplant.
An Open Shortest Path First (OSPF) protocol is the most used interior gateway protocol and computation intensive protocol where energy consumption in Internet Protocol (IP) networks is the main concern. The energy in an IP network can be saved by allowing a subset of IP router interfaces on sleep mode setting during the low traffic hours through the model of “move” by dint of an Energy Aware Routing (EAR) strategy, which is completely compatible with OSPF and is based on the “Shortest Path Tree (SPT) exportation” techinque or “Dijkstra's Algorithm”. In case of heavy traffic hours, the EAR strategy is not usable and may cause denial of service. The strategy implemented can help a network operator to control the network performance and allow a smoothed QoS degradation. This performance evaluation study permits to save about 30% of network links with a insignificant rise of link loads and network path lengths.
From this project I am able to seek the practicality of subjects which I have learned during my classes and implementing these functions I am able to learn more pros and cons than what I have learnt theoritically.
A network is merely a series of interrelated components, sharing information, linked by one common lifeline, spanning across a large area. When most people think of networks in the computer sense, cyberspace and the internet are usually types of networks that come to mind. However, these are just small pieces that complete the network puzzle. Many other types of networks include Local Area Networks (LANs), Wide Area Networks (WANs), and also wireless networks as well. This paper will provide some insight into the development, objectives, and impact of various network systems.
been used in the early 90ies. As a design teaching tool it used at MIT, Harvard, UCLA
... monitor all activity, and very easy to quickly control what gets in and out of a network.
3) P2P is more reliable as central dependency is eliminated. Failure of one peer doesn’t affect the functioning of other peers. In case of Client –Server network, if server goes down whole network gets affected.
Network Design is very important when it comes to implementing a connection between a computer and a server. According to Network world Websites, Network is defined as a “connected collection or devices and end systems, such as computers and servers, that can communicate with each other”(McQuerry). Network carry data in many types of environment, such as homes, small businesses, and large enterprises. Network Locations Is one of the major factors. There are different types and locations of network exist, including network in a home or home office to communicate through the Internet, to locate information, to place orders for merchandise, and to send message to friends. Whatever the reasons are, all these networks share common components. According to Network World, the most common network components are Personal Computer’s, interconnections, such as NICs, Networks media, and Connectors. Switches and Routers are also part of network components. When designing a network, couples of items are a must to have such fundamental goals, a drawing or diagram, The Hierarchical Network Design, IP addresses, routing protocols, Servers, and switches.
The beginning of any good network starts with planning, and one of the main points of planning involved is the network topology. Network topologies consist of both physical and logical maps, each variant having positive and negative aspects as well as applications where one type would be more appropriate. A lot of modern network layouts are hybrids of both physical and logical networks.
In recent years, network coding [1], [2] has been considered as an auspicious information network paradigm for augmenting the throughput of multiple unicast networks [5]. The pioneering researches of network coding were undertaken by R. Ahlswede, N. Cai, S.-Y.R. Li and R.W. Yeung. Their discovery, which was first introduced in [1][2], are considered to be the crucial breakthrough in modern information theory and the time of its appearance, is recognized as the beginning of a new theory-Network Coding theory. In these elegant, succinct articles, within the purview of rigorous mathematics, the glimmering of an optimal network protocol for multiple unicast network was introduced in which the key idea is considering digital information as wave [riis].
