Networking: A Beginner's Guide
Since you can predict the sites from which the user might need to access data, local
support may be available to help. For instance, you might have a way for the user to
log in to the distribution center's LAN and access e-mail and files at the headquarters
location through an existing WAN link, as shown in Figure 10-2. This type of user
needs e-mail, file access, and possibly access to a centralized application, such as an
accounting system.
The remote office user is in a single location and needs access to the corporate LAN
for e-mail and possibly for application access (see Figure 10-3). This person usually does
not need file access, except to send files through the e-mail system, because this person
maintains local file storage. This user is in a single location, so you can pursue certain
high-speed links that are not feasible for the travelers. A person telecommuting from
home would fall into the category of remote office user.
Sometimes a small group (two to five people) stationed in a remote location needs
certain services from the corporate LAN. These services are not cost-effective for this
group to have locally, yet these users have a small local LAN for printer and file sharing,
as illustrated in Figure 10-4. These users fall into the remote office group category, which
needs a combination of services. Partly they are like any user of a remote LAN, and
partly they are like a remote office user. They usually require a mixture of both types of
solutions for proper support.
