DISTRICT SUPPLIED SERVERS AND FUNCTIONS

All file servers are categorized as Enterprise or Workgroup type services, and then placed on the network topology according to function and anticipated traffic patterns of users.

DOMAIN NAMES SERVICE and EMAIL SERVICES

Domain Name Services (DNS) and e-mail delivery are implemented in a hierarchical fashion with all services located on the master server at the district office. Each District Hub location contains a DNS server to support the individual schools serviced out of that location. Each school site also contains a host for DNS and e-mail services that maintain a complete directory of all staff personnel and student population for that location. The school host is the local post office box and stores all e-mail messages. The update DNS process flows from the individual school server to the Hub server and to the district server. All regional servers have the capability to communicate between themselves, thus building redundancy in the system in the event that the District master server is unavailable. Should the District master server require a partial or complete restore of data, the ability to query any or all of the regional servers to acquire the needed information isprovided.

ADMINISTRATIVE SERVER

The school district is moving towards a totally automated server based administration system. Each school location contains an Administration server which houses the student tracking, attendance, grading and other administration functions. This server runs TCP/IP as its OSI layer 3&4 protocols and will only be made available to teachers and staff.

LIBRARY SERVER

The school district implements an automated library information and retrieval system, which houses an online library for curricular research purposes. This server runs TCP/IP as its OSI layer 3&4 protocols and is made available to anyone at the school site.

APPLICATION SERVER

All computer applications are housed in a central server at each school location. As applications such as Word processing, Excel, PowerPoint , etc are requested by users these applications are retrieved from the application server. This provides district support staff with a easy and efficient method for upgrading applications without having to reload new software on each computer in the district network. This server uses TCP/IP as its OSI layer 3&4 protocols and is made available to anyone at the school site.

OTHER SERVERS

Any other servers implemented at the school site are considered departmental servers and are placed according to user group access needs. Prior to implementation of other servers a requirements analysis must be submitted for the purpose of determining placement of the server on the district network.
