Sharing an Internet connection has become an increasingly complex undertaking in recent years. Not only do you have to provide users with sufficient Internet bandwidth to support their needs, but you must also consider the possibility of users abusing the Internet access you give them and be concerned with the dangers of having your pri vate network connected to the Internet. Your Internet access strategy must take all these factors into account before you even begin to implement it.

Calculating the number of users is not as easy as it might first appear. Of course, you can find out how many employees there are in the organization and how many of them use computers connected to the network. However, you must also determine how many users are working at any one time and how much of that time they spend access ing the Internet.

time, but then you have to determine how much time they spend actually accessing the Internet. An executive who sends an occasional e-mail and checks a fact on a Web site once in a while is distinct from a shipping clerk who spends the whole day using the Web to print shipping labels and track package deliveries.
What Applications Do the Users Need
Another concern is the Internet applications that the network users run and how they use them. A single e-mail user, for example, consumes little bandwidth, unless the user is attaching huge files to e-mail messages, in which case the bandwidth requirements can be high. Web browsing can vary from simple text pages to File Transfer Protocol (FTP) downloads and elaborate streaming audio and video applications that also con sume substantial bandwidth. You must attempt to estimate the Internet use patterns of the network s users and provide them with sufficient bandwidth to satisfy their needs.
Planning Estimating the appropriate amount of Internet client bandwidth that you should
supply for a network also depends on whether you intend to give the users full Internet access or whether you intend to limit them to certain applications, sites, or times of day. For more information about regulating client Internet access, see Lesson 2 of this chapter.
Another factor to consider is that client applications need not generate all your network s Internet activity. You might have to supply bandwidth for the organization s Internet servers as well, and estimating the amount of bandwidth these servers need can be even more difficult than estimating client consumption. Unlike the bandwidth for client Internet access, which network administrators often try to keep to a minimum, in most organizations the object is to draw as much traffic as possible to their Internet Web servers.
Lesson 1
Planning an Internet Connectivity Infrastructure
Real World Web Servers and Internet Bandwidth
Web servers provide product information and customer support that inside sales and customer service personnel would otherwise provide. As a result, factors such as new product release schedules and unforeseen technical support issues, as well as the overall growth (or reduction) of the company, can affect the amount of bandwidth consumed by Web servers. When estimating the bandwidth needs of Web servers, you should always provide a greater margin for growth than when you are estimating client bandwidth needs. A temporary slowdown due to a shortage of bandwidth can be an annoyance to company employees, but when customers experience problems, it can mean lost business. Another important consumer of Internet bandwidth these days is virtual private network (VPN) connections. A VPN is a type of WAN connection between network sites, or between a computer and a network, that uses the Internet as a network medium. Rather than use an expensive dedicated connection, such as a long-distance telephone call or a leased line, both parties in a VPN use a local ISP to establish a low-cost con nection to the Internet. The systems then use a special protocol to create a secured channel across the Internet (called a tunnel) between them. Some organizations use VPNs to connect branch offices, and others use them to enable traveling or telecom muting employees to connect to the company network without incurring long-distance telephone charges. VPNs can consume a great deal of Internet bandwidth, depending on the type and amount of data passing between the connected systems.
