Abstract
A VPN makes use of public communications but maintains personal information through a tunneling protocol – such as the P2P tunneling protocol – and security procedures. Over the Internet, a VPN uses public circuits that lots of users share. With some changes like high security measures, it can be created that only you can access and understand thoroughly. It is also an example of a creative use of the Internet. A VPN offers some advantages, but only if the Internet is used as a transfer medium. It can be created between any two points and is relatively economical. Also, if an Internet connection is achieved, the data that is transferred is free. A VPN also has a couple disadvantages, though. Its design and implementation can be complex, and reliability might become a factor. EDI is an electronic transaction between two companies. The bank’s funds can also be electronically transferred, too. VPN communications link isn’t completely private, so a better option would be to use some leased telephone lines. Some banks might need the telephone company to install a special circuit, though. There are some speeds (measured in Mbps); however, higher speeds can be more costly to implement.

Establishment of EDI/XML Techniques
A virtual private network (VPN) is a data network connection that makes use of the public telecommunications infrastructure but maintains personal information through the use of a tunneling protocol and security procedures. A tunneling protocol, such as the Point-to-Point (P2P) Tunneling Protocol, is the command set that allows an organization to create perfectly secure connections using public resources. A VPN over the Internet uses the public circuits that thousands of users share every second. With special routing information and high-security measures, however, a VPN can be created that only you can access and understand.
A VPN is one such example of a creative use of the Internet. As businesses continue learning to use the Internet, they will be able to expand into new territories and make better on existing communications strategies.
By using the Internet as the transfer medium, a VPN offers a number of advantages. Because the Internet is practically everywhere, a VPN can be created between any two points. And since the Internet is relatively economical, the VPN is, too. Once a connection to the Internet has been achieved (via an Internet service provider), data transferred over the Internet – and over the VPN – is free. The Internet – and VPN – maintains a relatively stable environment with reasonable throughput.
A VPN also has disadvantages such as: 1. The design and security implementation for a virtual private network can be complex. In other words, it requires a professor who is best at VPN configuration and knows about some security issues that occur during the usage of VPN. 2. Depending on your service provider, reliability can become a factor. If a VPN utilizes the Internet, it is important to choose a provider that has so little downtime.
Electronic data interchange (EDI) is an electronic commercial transaction between two or more companies. For example, a company wishing to purchase a large number of cell phones may send an electronic request to a number of cell phone manufacturers. The manufacturers may bid electronically, and the company may accept a bid and place an order electronically. Bank funds will also be transferred electronically between companies and their banks.
VPN communications link is not a completely private connection; hence, a better option would be to use leased telephone lines. A leased line is a full time dedicated, fixed-bandwidth, symmetric data connection. In this route, the bandwidth would be reserved for the bank. A leased telephone line would be used to create a network. Banks may need the telephone company to install a special circuit between two locations that no one else would be able to use. Leased lines can be used to connect to the internet, link their PC’s and Servers, carryout their phone calls, enable bank staff to connect to their work PC’s from home. Speeds of 2Mbps, 10Mbps, and 100Mbps are available. Higher speeds that exceed those speeds are also available, but they may be at a high cost for implementation.
There are advantages of leased line connection, like: 1. It is possible to get high uploading and downloading speeds. 2. Even in high workload, speed is not affected. 3. High reliability and data security.
There are also disadvantages of it, such as: 1. Compared to VPN or ADSL, it costs more to require using leased lines. 2. Installing it is more complex and it takes longer.
