Network design

The following parameters shall be based on while designing institution network: 

 

   Number of users in the institution: The number of network users shall be both employees and guests. 

 Services accessed or offered by the institution: Services shall be defined and categorized depending on operational and availability requirements. 

 Broadband technology: The technology to be used shall be chosen according to location, institutional business requirements, and offices set up. Wireless local area networks are advised for convenient and modernized work spaces. 

 Physical network diagram: The design of the physical network diagram will consider the number of users based on the institutional structure, the interior design/aesthetic of the building and sitting arrangement (i.e. whether all users sit on the same floor or on different floors) and shall also consider whether the infrastructure of the building is shared or not. 

 Logical network diagram: The design of the logical network diagram shall consider existing systems, services, and applications according to the institutional business processes. The design      should also provide the capability for scaling up and growth. 

 Network Security: All Government institutions shall comply with the current cyber security directives for network and information systems issued by a competent authority.
