Introduction
This documentation is about network design using a top-down design methodology. This
approach subdivides the task at hand into smaller simpler stages of coming up with a solution. In
this documentation, we are creating a wireless network design for a home delivery service in
Parramatta in Australia for OZ dispatch. OZ dispatch is one of the clients being granted a
network design solution. It has its main office at Parramatta and other 20 collection and delivery
centers. OZ dispatch deals with customer delivery and controls the payment process through a
website. OZ will be operating using office desktops and smartphones as the end devices in the
design network.
Project goal
The aim of this project is to come up with a suitable design of the organization that will aid in the
daily operations of the orders and delivery services to the customers. The network should also
create a favorable working environment for both the manager and the delivery officers. This will
be achieved by creating an efficient and scalable network in the OZ dispatch organization
considering its business goals and ts constraints together with the traffic goals and the trade-offs
as explained below.
Business goals and constraints
The business goals are customer and staff oriented (DiMicco, Millen, Geye, Dugan, Brownholtz and
Muller, 2009). The following are the goals.
 The customers of the OZ dispatch should be able to navigate through the web and place
orders in the system.
 The orders made by the customers should be dispatched to the CDCs accordingly.
 The orders made by the customers should be collected separately in the CDCs.
The following are the consideration of the constraints in the whole process of the design and the
delivery services.

 Time is a major constraint following the evolution in technology and the competitors
also. From this, before putting up a workable design, the analysis should be done on the
same scenarios and a report generated to guide on the construction of network design
(Singh and Chaudhuri, 2009).
 Cost is another constraint in that the expenditure of hosting an independent network with
its servers is a bit expensive although there is a need for the same in the OZ dispatch
organization.
 Another constraint on the same is the allocation of available resources as is a must for the
project’s success.
Technical goals and trade-off
Technical goals mostly rely on the network behavior, the efficiency and quality of the
networking devices and the security of the network from the information security to device and
equipment security (Hvolby and Steger-Jensen, 2010). This may include the following.
 Providing topmost security and installing access control features in the network.
 Availability of the network all along to ensure a smooth flow of daily activities in the
organization.
 Network efficiency providing efficiency in communication and data transfer among the
organization.
 The network scalability should be more scalable to give room for expansion even in the
future.
On the trade-offs aspects, we shall have the following in the OZ dispatch organization.
 Security.
In order to achieve a high-level security detail on the network, the employees and the
users must be restricted from unwanted performances in the network. The employees
should not download any unnecessary files from the internet.
 Network performances
This can be increased by increasing the bandwidth of the network.
 Network availability.
The network availability can be achieved by adding additional back up lines to the
network.
