General:

A protocol is an agreed upon format for interaction at the computer as well as the human level. A protocol stack is a series of protocols arranged in layers, each layer performing a single, well-defined function, with clearly delineated interfaces, which permit functional replacement at a layer­by­layer level.


The purpose of this document is to inform the reader regarding the Local Area Network (LAN) protocols and wiring at the Department of Human Services (DHS).
Guideline:

Protocol Standards and Wiring Guidelines
DHS requires the use of a minimum of category (CAT) 5E wiring, with a recommendation for CAT 6, for short distance wiring. DHS requires fiber optic cabling for longer distance connections, such as in multi-floor office complexes where fiber is used as riser cable, and campus facilities where the distance between buildings exceeds CAT 5E/6 specifications.

As an extended Ethernet LAN, the DHS network requires the use of the IEEE 802.3 protocol at the local site level. The network supports only Internet Protocol (IP) at the enterprise level.


Refresh Schedule:

All guidelines and referenced documentation identified in this standard will be subject to review and possible revision annually or upon request by the DHS Information Technology Standards Team.
