Introduction
Network design is comprehensive planning to implement network infrastructure within the
organization or an institution or onset area. The designing methods are used to put in place
the different network topologies. These methods have their pros and cons during their
implementation process which are stated in this document. The various design methods that
are used to design and implement network infrastructures are as follows:
Hierarchical Network design.
The hierarchical network design is an approach that is used to develop multiple networks by
grouping several devices together. This design method has three layers; the core layer is the
first layer connects all the devices in the distribution layer providing the maximum
throughput in the network between different sides and enables the network growth. The
distribution layer is the second layer connects together network in the local area and provides
the policy-based connection between the core layer and the access layer (Cisco, 2014).The
access layer is the third layer which acts as the connection link between the host's network
and the devices of the end-user.
The pros and cons of the hierarchical network design method are:
Pros
 It is easier to design
 It provides a high level of security
 It allows for traffic multiplexing.
 There are backups available therefore network failure is minimal
 There is an easy expansion of the network thereby allowing many users to connect to
it without causing problems.
Cons
 The materials that are used to develop the network design are more making it
expensive to implement.
 It is not easy for administration and maintenance when network is large.
