This paper will Describe in detail what Virtual Private Networking is and how it is used in companies. It will cover all of the benefits, as well as the problems encountered in achieving success with this facilitator of social software. It will give examples of companies and how they use the technology, it will provide case studies of companies that have used the technology successfully. It will review the author’s thoughts of how to use VPN in a common workplace.
Then it will show you how to implement VPN on a network, through both hardware and software installations. You will see how employees collaborate with this tool and use it to increase productivity. You will see the obstacles that you would encounter with a VPN system and how to overcome those obstacles and solve problems that might occur in its everyday use.
Later in the paper you will see the more popular products available that support VPN and you will also see a price comparison of those products. Near the end of the paper you will see an estimate that adequately shows the cost of full implementation in a business workplace.
A virtual private network (VPN) uses a public network infrastructure to make the connections among geographical dispersed nodes. It can also be described as a logical local area network that connects an organization’s geographically dispersed sites in a way that makes them appear to be part of one single network. A VPN differs from a typical wide area network in the following way. Instead of a hardwired pipeline between nodes of a standard wide area network using a dedicated connection, the connections of a VPN are made through a web of cables of a public network such as the Internet.
There are several ways a companies use a VPN. A VPN can do anything a leased line wide area network can do and more. Companies connect to geographically distant facilities into a cohesive network. By using the international resources of the Internet, a VPN can offer connectivity virtually anywhere in the world. This allows a company to expand globally. Company use VPN for remote access services. It is not only an extremely cost-effective way to service a mobile workforce or telecommuters but it allows workers to connect into the home office through an Internet service provider from anywhere in the world, riding through a public Internet to l...

...igh performance techniques that are available. This series is the “most feature-rich carrier-class VPN product line on the market.”(digital warehouse) The concentrator ranges from $5,000-$19000 as the Encryption Service Processor ranges from $40,000-$60,000 and the Power Supply Spares and Options are from $50-$5,000.
The cost for a system to be installed in a company mainly depends on the size of the company. The smaller companies will typically use the less expensive and the larger the companies will use the more expensive system. Overall, for a high quality VPN system a company would pay about $8,000. This price depends on whether or not the company needs the accessories or an upgrade kit or spares for the system.

As technology improves, businesses expand and recruitment pools decrease, organizations contemplate ways to, not only reduce the overhead costs of doing business but, to attract new talent in a competitive employment marketplace (Darleen, 2012). To do so, many organizations have redefined what it means to ‘go to work’, in terms of not only the act of getting there, but how work is accomplished and where (Lojeski & Yuva, 2008). A study conducted three years ago by the Society For Human Resource Management (SHRM) reported that almost half of the organizations surveyed utilized virtual teams (Minton-Eversole, 2012). Anyone who conducts business using mobile technology devices is considered
AT&T provides professional network service to enterprises. Services for Asia Pacific region include integrated Global Enterprise Management System, Internet data centers, voice over internet protocol, virtual private network, and data hosting. In order to provide a complete network solution to clients, AT&T, at the backend, is supported by their own data/network center, protocol and the undersea cable network. AT&T is proposing a network solution to one of their big clients BHP Billiton. BHP Billiton has subsidiaries in over 30 countries and they are considering to implement a professional network for better internal communications. The project will involve setting up an approximately two hundreds network sites in different countries within a tight time flame. The successful of wining this contract will drive AT&T Asia Pacific team to earn double of their existing annual revenue. This would be very attractive to AT&T due to the lost of a number of clients as a result of the economic crisis earlier in the year. An effective strategic decision process, as found by ...
Another benefit of an online portal is that users can work from home or from satellite offices as needed. For the sake of redundancy, it may be prudent to keep the Virtual Private Network (VPN) connection to our satellite office; however, it would not be necessary. It would also be wise to remove the RAS and PBX from the company network. These legacy systems allow remote dial-up users to authenticate to the network, but their functionality could be accomplished through a web browser under the new system.

Virtual Private Network presents some advantages over the traditional network technologies. VPN offers direct cost savings over leased lines or long-distance calls for remote access, savings resulting from reduced training requirements and equipment, increased flexibility, scalability, and security. The main advantage of VPN is the cost savings of Internet VPN when compared to networks built using conventional leased lines. Leased lines include tariffs that have an installation fee, a fixed monthly cost, and a mileage charge. The cost to an organization of traditional leased lines may be reasonable at first but can increase exponentially as the organization grows. As an organization grows and more companies must be added to the network, the number of leased lines required increases dramatically. VPN that utilizes the Internet avoids this problem by simply tapping into the geographically distributed access already available. Another way VPN reduces costs is by reducing the need for long-distance telephone charges for remote access. Instead of having the offsite team of a company dial into the corporate modem bank via long distance lines, the company’s VPN allows them to simply place local calls to the ISP’s POP in order to connect to the corporate network.

Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPN's permit secure, encrypted connections between a company's private network and remote users through a third-party service provider. A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPN's have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion to the distances involved, the geographic locations of each office matter little in the creation of a VPN.
A Virtual Private Network, more commonly known as VPN, is a type of technology that provides secure private connection for users who connect to public networks, such as the Internet or company network. It is a safe and secured channel through which data are transmitted without exposing these data to anyone.

I experienced that when I want to connect to the Bilkent Virtual Private Network, I have connection problems and I conducted a survey to see whether this is common problem or not. I asked the question “Are you have connection problem to the Bilkent VPN server?" the answer is clearly indicates that this problem is not use related problem. It is totally server related problem because %74 of participants votes for "yes" [5]. Since the Bilkent VPN has a vital importance to complete numerous tasks, solving this problem has a direct relation with increasing performance of the Bilkent students. This proposal intends to examine the factors creating a connection problem and investigates possible solutions to change this negative state by taking cost and duration of the implementation into account.

Corporate Networks in organisations can be complex structures that “requires a great deal of attention” (Clemm 2007). Even small companies can have quite complex networks that are a considerable investment to the business. The notion that corporate network management is a cost to a business rather than a continual beneficial investment is a naive assumption that requires further investigation to the benefits that network management brings. Clemm (Clemm 2007) states in his text that the ultimate goal of network management “is to reduce and minimize total cost of ownership”, improving operational efficiency and lowering cost. Clemm (Clemm 2007) also notes that “Network Management is not just related to cost and quality”, which will be an continual concept presented throughout the report. The report will address key issues with corporate network management and ultimately argue and justify that corporate network management must be seen as a positive benefit to the business and not as a continual expense. The supporting articles will also provide sound evidence that networking is crucial to a business’s processes and production which can be seen from the OpenSSL Heartbleed Security vulnerability fiasco (Nieva 2014) or the QANTAS Amadeus system failure (Heasley 2012).
The proposal will talk four Internet services that are essential to enable efficient and secure communication with customers and internal staff. And for each Internet service I proposed, describe its usage and explain why the service is appropriate.
Cable modems have only recently been introduced for private commercial use. Cable modems and the cable data networks they are a integral part of hold the promise of providing a great deal of communications bandwidth for the private user. Greater bandwidth equals greater speed in the realm of the Internet. The Internet has only been around for private use for a relatively short period of time, nonetheless, it has grown quite rapidly. It appears that the Internet will continue to grow at a rapid pace. People will begin to use the Internet for more and more applications. Network...
