The next time a person accesses that same site, the content comes from our network - without another request going back out to the Internet. This has helped keep the traffic load manageable. We have been very happy with the performance. Figure 1 illustrates the Lee County Senior High School's current network that connects the three computer labs. Since that initial installation, the county has also implemented a similar system at its Greenwood Elementary school where students access the Internet from a network of 100 Macintoshes.
Plans call for the addition of two more labs at the high school level.
A T1 line and a Frame Relay-based network would expand communications capabilities, allowing connection of additional Lee County schools and students. Both ASI and URLabs specialize in offering turnkey solutions that meet the specific needs for safe and instructional Internet access for schools. Solaris provides powerful functionality, but users and administrators never see it at this application level. URLabs and ASI also provide excellent support. The Level I and II curriculum closely follows state guidelines, developed in part by Cotten.
