List of Business Goals and constraints
The business goals for the OZ Dispatch organizations have been described below:
 The customers of the organization would be able to make online orders in the system.
 The order collection are done in the collection and distribution centres of the
organization.
 The dispatch centre of the organization would be dispatching the orders made by the
customers in the organization.
List of technical goals and trade-off
The technical goals for the organization are:
 Providing efficient communication by mailing and data transfer facilities in the
network.
 Providing excellent security and access control features within the network.

Model for addressing and naming
For the addressing of the system the sub netting concepts would be used and hence
the manually allocation of the addresses to the network end users would be done. The DHCP
server addressing is used which would be assigning automatic addresses to the network end
devices and the after the addresses are allocated dynamically the separation of the sub
networks would be done. Hence, each of the router would be allocated separately to the
DHCP server so that the dynamic addressing is done within a certain range only.
Explanation and justification of the logical network design
The network design for the OZ organization involves a topology, which uses a ring
topology and a hybrid network topology within network design. The network has also be
secured with a firewall. In addition to this all the centre of the organization in the network
would have wireless routers installed in the network which would be providing wireless
access to the users in the network. In addition to this the servers installed in the network
would be helping the network to allocate facility for their users in the network.
