Introduction
Flame publishing house has database developers that ensures that all data of this organization is
stored in a centralized place. It also has one network engineer. The flame publishing house
organization has 20 employees and three administrative stuff at woodlands. The local area network
should cover the five storey building of Flame publishing house. Having in mind that the accounts
department has computers with 3 stuff working there. If the devices are allowed to fight for
bandwidth others will benefit while others will not benefit at all (Kreutz,Ramos,
Verissimo,Rothenberg,Azodolmolky, & Uhlig,2015). A router which has good quality service will
not allow for the fight of bandwidth by the devices but allows for equal distribution of the
bandwidth. It also considers devices needs for the bandwidth distribution. Some routers have
options for QoS. The latest ones enhance the use of wi-fi multimedia. This prioritizes network
traffic from highest to the lowest. They goes ahead and prioritizes the use of network for example
prioritizing the video and the voice in front while download of file is not such prioritized. If
hierarchical design is used when building a local area network the plan tends to be more successful
for small and large businesses. Hierarchical network is more easier to implement and expand it as
compared to other network (Mittal,Chen, & Cisco Technology Inc, 2016). Flame publishing house

has database developers that ensures that all data of this organization is stored in a centralized place.
It also has one network engineer. The flame publishing house organization has 20 employees and
three administrative stuff at woodlands. The local area network should cover the five storey
building of Flame publishing house. Having in mind that the accounts department has computers
with 3 stuff working there. This is the cost where a user is unable to access the server. If that cost
tends to rise then you must have a budget that goes with it well. When the network is complex it is
more difficult to maintain, monitor or configure. The network should be design in a manner that is
very simple. This includes the cost of adding functionalities to the present network and moving to a
new location. Knowing what you need in future not only saves on time but also saves on money
(Amiri,Dehghan,Lan,Yue,Yang, & Quantenna Communications Inc, 2017). Installation of the
networking hardware and software can be the most expensive if the organization is big. The cost
includes the paying for the labor. Other thing to consider here is well planned wiring and color code
convention for cable runs. This considers the cost of a response of 4 seconds time with that of
almost half a second response time.This focuses on what is being purchased on the organization.
The cost includes the purchase one, installation, maintenance and upgrade if any available
(Oberst,Wegmann,Stodt,Brand, & Chamarro,2017).
Section 1
1) Plan of designing local area network
If hierarchical design is used when building a local area network the plan tends to be more
successful for small and large businesses. Hierarchical network is more easier to implement and
expand it as compared to other network (Brundage,Rhoads, & Digimarc Corp, 2015).
Hierarchical Model Network
Access Layer
It interfaces with devises such as PC’s, printers and phones. It includes routers, switches, hubs and
bridges.

Distribution Layer
It aggregates all the data that is received from the access layer before it is trained into core layer
which is a final destination. It controls all the flow of network through a given policies by forming
functions on virtual local area network (Sidhu,Kim,Pathuri,Yerramsetti, & Belkin International Inc,
2017).
Core layer
It is the high speed backbone of the network. It is the main layer between the three thus it is
important for it to be available and redundant. It can also be connecting to the internet.
Matching switches to specific local area network functions
We need to select appropriate switch for one of the hierarchical network hence must be having that
gives details on the specific target flow. To get the appropriate switches we consider different
topologies.
Traffic flow analysis

It is a way of measuring bandwidth usage on any network. This allows data analysis for the purpose
of tuning, capacity planning and improving on the hardware of the network (McCann, Montemurro,
Durand, Nathwani, & BlackBerry Ltd, 2016).

2) Test plan
Optimazing availability and cost
There are three major elements for network design problem
a) Environment – This includes the location of the host, servers, terminals and the project cost for
delivering all the required networking specifications.
b) Performance – It touches on the reliability of the network, throughput, host/client computer speed
c) Network variables – It includes the network topology, line capacities and packet of flow
assignments.
The main purpose here is to minimize the cost of developing a network here while the services of
the networking are reliable and easy to maintain.
Cost
Hardware and software cost – This focuses on what is being purchased on the organization. The
cost includes the purchase one, installation, maintenance and upgrade if any available.
Performance cost – This considers the cost of a response of 4 seconds time with that of almost half
a second response time.
Installation cost – Installation of the networking hardware and software can be the most expensive
if the organization is big. The cost includes the paying for the labor. Other thing to consider here is
well planned wiring and color code convention for cable runs.

Cost of expansion – This includes the cost of adding functionalities to the present network and
moving to a new location. Knowing what you need in future not only saves on time but also saves
on money.
Cost of support – When the network is complex it is more difficult to maintain, monitor or
configure. The network should be design in a manner that is very simple.
Downtime cost – This is the cost where a user is unable to access the server. If that cost tends to rise
then you must have a budget that goes with it well.
3) Security requirements and quality services needed for selection of accessories
All the devices connected to a router fights for the bandwidth with other devices connected to the
same router. If the devices are allowed to fight for bandwidth others will benefit while others will
not benefit at all. A router which has good quality service will not allow for the fight of bandwidth
by the devices but allows for equal distribution of the bandwidth. It also considers devices needs for
the bandwidth distribution.
Intelligent QoS
Some routers have options for QoS. The latest ones enhance the use of wi-fi multimedia. This
prioritizes network traffic from highest to the lowest. They goes ahead and prioritizes the use of
network for example prioritizing the video and the voice in front while download of file is not such
prioritized. Some routers have options for QoS. The latest ones enhance the use of wi-fi

Quantenna Communications Inc, 2017). Installation of the networking hardware and software can
be the most expensive if the organization is big. The cost includes the paying for the labor. Other
thing to consider here is well planned wiring and color code convention for cable runs.
Streamboost
This helps in distinguishing between prioritize latency sensitive traffic and the latency insensitive
traffic.

4) Maintenance schedule to support the LAN
Installing, upgrading and replacing software and hardware in a network
Replacing, installing and upgrading are the most common tasks carried out in a network. This
includes replacing of a older hardware or software in an organization such as switches, routers and
hubs. From the software part is cisco IOS image.
Monitoring the network
Monitoring of the network is one of the most effective way of carrying out maintenance in a
network. If monitoring is carried out time to time, potential problems are detected over the network
before affecting the users of the network.

Documentation of the network
Most of the networking engineers consider documentation of the system as non important and of
less task while on the reality it is the most important when it comes to maintenance and assists the
support while trouble shooting the problem over the network. For this, it is important to note that
the levels of documentation varies from one company to another one.
Security of network from external attacks
Network security is the main component of the to consider while developing a network in an
organization. Organizations should have a dedicated team of security for checking probably security
vulnerabilities. Some routers have options for QoS. The latest ones enhance the use of wi-fi
multimedia. This prioritizes network traffic from highest to the lowest. They goes ahead and
prioritizes the use of network for example prioritizing the video and the voice in front while
download of file is not such prioritized. If hierarchical design is used when building a local area
network the plan tends to be more successful for small and large businesses. Hierarchical network is
more easier to implement and expand it as compared to other network (Mittal,Chen, & Cisco
Technology Inc, 2016). Flame publishing house has database developers that ensures that all data of
this organization is stored in a centralized place. It also has one network engineer. The flame
publishing house organization has 20 employees and three administrative stuff at woodlands. The
local area network should cover the five storey building of Flame publishing house. Having in mind
that the accounts department has computers with 3 stuff working there. This is the cost where a user
is unable to access the server. If that cost tends to rise then you must have a budget that goes with it
well (Farhady,Lee, & Nakao,2015).
Section 2
Networked system implementation

Flame publishing house has database developers that ensures that all data of this organization is
stored in a centralized place. It also has one network engineer. The flame publishing house
organization has 20 employees and three administrative stuff at woodlands. The local area network
should cover the five storey building of Flame publishing house. Having in mind that the accounts
department has computers with 3 stuff working there.
This leads to high end reliability in terms of storage of data in an organization.
Hierarchical network design
Hierarchical network design ensures that the bandwidth is optimized for the traffic of the network to
stay locally in the network of the organization. There are three layers; access, distribution and core
layers (Pathak,Feng, & Mohapatra,2015).
