We will assume a data center in Chicago, where the head
office also is located, and approximately 100 branch offices
clustered around major cities, such as New York, Atlanta, Dallas,
San Francisco, and Los Angeles. A typical branch office has 20 PCs
that need access to hosts located in the Chicago data center, local
applications, e-mail, and the Internet. There also is a growing need
to support staff working from home and roving users with dial
access. |
