Notes on Network Planning

  1. Determine what currently exists.
    1. How many computers.
    2. What kind of computers.
    3. What are the people doing with the systems.

  2. Determine the goals of the network system.
    1. What type of applications will the users be running?
    2. What resources will be shared?
    3. Who will communicate with whom?
    4. What are your security requirements?
    5. What other systems will be connected?

  3. Determine the groupings in the organization.
    1. Physical groupings by location.
    2. Logical groupings by organizational structure.
    3. Determine server locations.
      1. Centralized servers
        1. Easiest to manage.
        2. Increases backbone network traffic.
        3. Effective when most users access many servers.

      2. Local servers
        1. Reduces backbone network traffic.
        2. Most effective if a group primarily uses a single server.

  4. Design the physical network.
    1. Estimate network load.
    2. Plan the wiring.

  5. Workgroup Security model
    1. Users manage their own system
    2. Similar to Windows95
    3. Peer to peer sharing
    4. Good for small networks of capable users

  6. Domain Security model
    1. Centralized management of accounts and security
    2. Single logon for all servers
    3. Good for large networks, multiple servers, non-expert users.
    4. Domains can extend "trust" to other domains.
