LO 1
1.1critically evaluate different LAN technologies
LAN stands for Local Area Network which is a part of computer network for connecting various
terminals located in a place or a building for proper communication among them to share
information and resources. Devices in the network can be connected either using or wires or
wireless. All the devices in the network can receive and send information that is addressed to it
specifically. Some of the examples of LAN technologies are Ethernet, WLAN (using 802.11),
and Token Ring. Standards are sets of rules that are followed for data transmission.
Ethernet
One of the most commonly used LAN technology is Ethernet because it is quite easy to
understand, implementing the network structure is simple and maintenance and implementation
is very less when compared with other LAN technologies. Under 802.3 of IEEE standards,
Ethernet is defined. In Ethernet computers are connected using cables and this network can
connect 1024 workstations and computers.
In terms of topology Ethernet is very flexible. Ethernet is capable of providing 100mpbs speed
but most of the network used only 10mpbs.
Figure 1: Ethernet connection using the Ethernet cable
2

Figure 2: Wired Ethernet network using fibre optic cable
In wired Ethernet all the devices in the network are connected with one other using a fibre optic
cable and the network is mostly within 10km (Kumar and Malhotra, 2015). To resolve issues of
collisions for sending information CSMA/CD is used. While on other hand in wireless Ethernet,
systems are connected using NIC (Network Interface Card). NIC uses radio waves for
establishing communication using a wireless switch.
Figure 3: Wireless Ethernet Network using NIC
Wireless LAN (WAN)

WAN or wireless LAN is also called as LAWN (Local Area wireless Network) in this type of
network mobile devices is capable of connecting to a LAN using a wireless connection. WLAN
is defined by using radio or wireless connection (Rao et al 2017). It is well defined by IEEE
802.11. This network allows the user to move free around the coverage area of the network.
Figure 4: Wireless LAN
Every element of WLAN is considered as station that is categories as either clients or access
point. APs are the one that receives or transmits signals using radio frequency operating like a
router whereas client can be a workstation, computer or phones.
Token ring
Token ring network also falls in LAN; here all the computers in the network are interconnected
in star topology or in ring topology. And logical token are being passed from one host to other.
In a network using token ring does not support colliding of data packets as data here can be sent
by only the token holders. IEEE standard defining this network is 802.5. Data in this network can
be sent at speed of 4, 16 and 100Mpbs.

1.2 critically analyse traffic intensive services and their performance
QoS or Quality of service in the ability of network to provide maximum output by achieving
maximum possible bandwidth along with overcoming of other network issue related to
performance such as error rate, latency and uptime. Proper management of quality of service is
required in a network for proper management and controlling the resources by prioritising data in
the network (Ali, 2017). QoS of a network can effectively improve by using various techniques
of traffic shaping. Main aim of QoS technologies applied in a network is make video, voice and
data union more clear to all the end users. QoS is considered to be an essential element for an
efficient network convergence of video audio and various data in the network.
The first aim of the QoS policy applied in any network is to identify the traffic that needs
attention. Various marking tools are used for doing these some of them has been mentioned
below:
In Layer 2, Multiprotocol Label Switching Experimental Values, 802.1Q Class of
Service bits.
In Layer 3, IP Precedence, Differentiated Services Code Points and IP Explicit
Congestion Notification
In Layer 4 , TCP/UDP and source-destination ports
In case of Layer 7, Network Based Application Recognition is used for signing
applications.
802.1Q/p CoS
In layer 2, Ethernet frames can possibly be marked according to their importance. It can be done
effectively for which User Priority bits 802.1p is set from the header 802.1Qr. Marking is
possible for only 3 bits in 802.1p. In the Ethernet frame of layer 2 it is possible to set only 8
different classes of service.
DSCP
In modern 3 IP network qualities of services can be provided by using DSCP or Differentiated
Services Code Point. For classification of packets in the network, DSCP mainly uses 6-bit field
for Differentiated Services in IP header. DiffServ referred to a networking architecture. Here
6

managing and classification of the traffic in the network in an organisation is done using a very
scalable and simple mechanism.
In the above figure the 1st six bit represents code-point which affects mainly per hob behaviour of
every node. When two devices are connected in a network, to achieve proper QoS those devices
must be connected and configured end-to-end.
IP precedence
ToS has 8 bit and the first three bits denotes precedence. When an IP pocket is more significant
then value of precedence is higher (Karakus and Durresi, 2017). If any kind of congestion is
found in the network, then the packet with low precedence will be dropped from the network by
the router. ToS is a network has the bit that denotes the kind of throughput, delay, reliability the
user wants.

1.3 Discuss LAN concerns and make recommendations to sustain network security, reliability
and performance
When a network is implement for transmitting data it is expected that the network to be secure
providing proper confidentiality of data, appropriate message authentication and to protect all the
transmitted data over the network so that no unauthorized changes can be made. Presently LAN
are not limited or restricted over a place, therefore its security has become a reason for concern.
Security threats in LAN comes are in various forms some of the common concerns are Viruses-
mail attachments, probes, Trojan horse, worms. Hence to avoid all the threats proper measure
must be taken some of them has been mentioned below-
Switch port control
Switchport security is one of a significant feature that is required for protecting the network from
being affected. Through switch port the addresses for sending the traffic in the network are
limited according to the requirement of the user. Switch port security in a network helps in
attaining network security by protecting computers that are connected along with the network the
devices are connected (Beberlein et al 2017).
Port security by default is disabled. Hence for enabling it switch port port-security command is
used. It stops the attacker by tying the MAC addresses for a particular port. When the link is
secure the MAC addresses associating the port disappear normally. The most recommended and
common setting for port security is dynamic mode where one MAC address is assigned for a port
to connect a single device.
Figure 6: Port security configuration script

ACLs
Access control list as the name defines is a list that controls the access of devices. These are the
filters that are used mainly by the router and switches for restricting unwanted data and allowing
the needed data. When an interface is configured with ACL then all the network devices analyses
the data by using the interface and then compare the list for flow of the data either to permit or to
restrict.
Figure 7: ACLs used for network security
Main objective of ACL is to provide network security. The functionality of ACL is for protection
of the devices and data for interfaces with high speed and if the firewall is unconfirmed
(Belhaouane,et al 2015).
Figure 8: Ingress and Egress of ACLs
10

From the above figure it is cleared that ingress traffic is those that flows from host to router
while egress is those that flows from router to Host network. The list initialises from source
address at first while configuration and then to destination. Access control lists are considered to
be a significant component for maintaining security of the network hence it must be placed
accordingly for acquiring it efficiency.
Wireless security
Completers and data in it can be destroyed using wireless network by using software tool, hence
wireless security is an essential element. In general wireless security are of two different kinds.
First is Wi-Fi protected access and second is wired equivalent privacy. Therefore, applying
wireless security avoids risk from intruders.
Encryption
Data security can also be maintained by using data encryption techniques where the data are
encrypted that makes in unreadable for any user with a key for decryption (Alsahlany, 2014).
During communication encryption is essential with the purpose that information cannot easy
understood by the intruder with an intention of eavesdropping.

LO2
2.1 design a LAN infrastructure for the company which will facilitate all of their requirements
According to the organisational requirement and suitability of a network system a LAN is
designed.
Figure 9: Network Design For The Organisation
Devices in the network:
12

Users: On the basis of voice data and textual messages received and sent the performance and
quality of the network must be assured by the user. As per the expectation of the organization,
network is scalable and effective with the implementation of latest technology and devices used
in the organisational network.
Technology: While designing and implementing the network for the organisation various
technologies are been used. Exclusive host control protocol is used for device identification
individual for all the floors. It helps in proper management for elimination and low maintenance.
The network uses Switches for device grouping using VLAN in where the STP is implemented
so that breaches in package routing can be ignored (Chowdhury, 2013).
VLAN is used for sharing and connecting several LAN devices with the help of switches.
Systems can link with their required resources though Hybrid topology. Routers used in the
networking system are used for transmitting data packets or messages from a device to another
using proper credentials of the device site. Switches used in the network are mainly for its
extension and grouping so that network can be controlled and monitored effectively. For
avoiding security issues Network uses firewall.
Traffic intensive services: On the basis of the network traffic networking service must be
prioritised so that high performance and quality is attained. For the purpose of communication
different protocols are developed according to the requirement and expectation of the
organisation.

2.2 critically evaluate the suitability of LAN components
For designing the network for Foot-Fall Field Marketing Ltd organization various technologies
and devices were used. For user contentment, number of technologies must be used according to
the specification and demand.
Hardware tools
Different hardware is used in the organisational network system for proper functionality of the
network.
Routers: A router is considered to be the main component of LAN. A router is used in the
organisational network for proper connectivity and data sharing along with the internet. It helps
in extension of network with different other device
Switches: Switches along with routers are used in the organisational network for integrating and
segmenting devices. Switches are effective to isolated network and segmentation of device is
essential for easy upkeeps. Switches also supports VLAN execution while applying IP addresses
for attaching additional devices using subnet mask.
Technology: For identification of all the devices connected within a range DHCP is applied
regardless of using any external system (Cisco Press, 2009). VLAN used in a network helps in
offering the information of device among various departments situated in different floors. For
increasing package routing, ad monitoring performance and resources utilization network uses
STP.
Firewall: Main purpose of firewall is to provide network security and to restrict any kind of
invalid requests made in the server devices. Both software and hardware component in the
network is configured with firewall and Access control list for their protection. An IT manager is
permitted to access other system through the access control lists.
Storage: Along with the internal storage system the organisation also chooses to have external
devices for storage mainly for data backup. Backup are helpful for searching data and
information in case of system failure or lost communication in case of any external outbreaks.
Software tools
14

For achieving effective performance and functionality of the network various software tools are
also implemented in the network. Some of them has been discussed below:
IOS: For security and robust performance of the network, routers and switches has operating
system powered by Cisco. O.S of the devices helps in achieving the hardware level
configuration. The operating system is compatible even with graphical user interface.
Negios: It is one of the important tool used by the organisation for analysing the network
performance along with troubleshooting. Negios generates reports regarding security log that
helps in effective decision making. The tool also generates alerts in case of security breaches
helping in network management along with providing recommendation for improving the present
network.

3.2 implement network security on a LAN
Foot-Fall Field Marketing Ltd must have a secure and protected network. Therefore, the
organization must configure various devices in VLAN and access control list (ACLs) must be
effectively implemented.
Virtual Local Area Network membership:
To get VLAN membership switches are configured along with the use of interfaces and IP
address. The Subnet mask for the network is defined. Steps to be followed for configuration of
VLAN membership.
Step 1: Login is done for web configuration and navigation for VLAN membership, LAN and
networking is done.
Step 2: The option add row is selected so that configuration can add new row.
Step 3: Providing VLAN ID, description, inter VLAN routing and pot numbers by the user.
Step 4: Noting the status of inter VLAN routing either enabled or disabled.
Figure 16: Steps for configuring of VLAN membership
Access control list implementation:
Foot-Fall Field Marketing Ltd organization firstly need to configure firewall to get access for
controlling the network accessibility. Configuration of firewall in all the systems in the
organisational network is required to have control over the network regarding traffic control on
for data protection from illicit user. Firewall inspect any kind of suspects and malicious code in
the traffic. ACLs comprises two lists one that allow a user and other that deny.
20

Figure 17: Implementation of ACLs
Domain name service:
The organisation must configure DNS for security purpose. Configuration of DNS translates IP
addresses and to know the network. DNS is useful for blocking and discarding unwanted and
unknown addresses from being translated so that end devices cannot receive data from the user.
Figure 18: Configuration of DNS
21

Authentication:
Password and usernames can be set for securing the computers and other devices present in the
networking system. Hence, the network configures switches and routers for setting them along
with allocation of port numbers. Encrypted commands are used in the network for secure the
configuration of devices in the network.

LO4
4.1 critically discuss how this LAN infrastructure will be monitored and managed (via
troubleshooting) if there is any issue during post implementation period
Local Area Network for the Foot-Fall Field Marketing Ltd must be monitored frequently for
managing and improving the network performance and functionality. Network monitoring helps
in increasing QoS (quality of services). For acquiring a reliable and secure network in the
organization some of the tools must be used for appropriate management of LAN:
Checking all the Configuration: All the devices in the network must be configured according to
the custom setting and parameters for default values so that targeted network cannot be
infiltrated. Hence, erroneous configuration will be avoided that will in turn enriches systems
performance.
Analysis of Bandwidth and Traffic: The network traffic is monitored by using network
monitoring tools for improving the bandwidth utilisation among devices and to minimise
resource load in the network by developing new and advance strategies. In case of high network
traffic, the organisation must opt for adding other devices that supports organisational operations
along with cable adaptation delivering appropriate bandwidth to all the end devices.
GFI LAN guard: Foot-Fall Field Marketing Ltd organization uses GFI LAN guard for
managing the organisational network (Delmar, 2009). GFI LAN guard is a commercial tool that
effectively monitors bandwidth utilisation by generating real time data, identifies threats and
improves network performance. GFI LAN guard helps in providing a reliable and secure
network.
Microsoft’s network monitor tool: These is one of the most commonly used monitoring tool.
It analyses the organisational network along with monitoring the performance. Microsoft’s
network monitor tool generates reports for network and performance.
26

4.2 Resolve LAN issues to improve security, reliability and performance
The above proposed design of the network for Foot-Fall Field Marketing Ltd organization is
quite functional to meet all the demands and requirements of both sales and marketing
departments. However, there are few concerns that the organisation network faces that may even
lead to network failure causing various loss to the organisation. Few of the issues and their
solution that the organisation can adopt is stated below:
ISSUES DESCRIPTION AND SOLUTION
Security An organization faces lots of issues due to deficiency in
security features in the network in regarding to store data. For
security purpose access of the important organisational data
must be restricted to specific users. Systems as well the data
can be protected by examining the accessing requests and by
monitoring data packages, emails for any kind of malicious
codes in the traffic.
Connection errors In a network, all the devices may be connected either
physically or logically. In some cases, connection between the
devices in the network may be lost while making any changes
or while adding new devices in the network. Organisation can
face performance issues id the connection string is unable to
support more devices (Lemeshko et al 2015). Therefore,
alternative paths and cables of high quality can be used for
device connection in organisational network for resolving uses
of connectivity.
Weakening of network
performance
The organisation uses Bus topology as recommended for
connection of devices in the network that can lead to
performance deteriorating if new devices are added to the
network plan. Hence, routers and switches must be used in
Foot-Fall Field Marketing Ltd for connecting devices to
enhance and improve performance of LAN.
27

For enhancing the performance of the network system of Foot-Fall Field Marketing Ltd it is
requires to improve configuration of devices in the network. All the devices in the network can
be secured by appropriate and timely maintenance.
28

4.3 critically evaluate the performance of a LAN

Table 2: Table For Evaluating The Network Performance
FEATURES DESCRIPTION
Hardware configuration and
utilisation
1. All the network components both hardware and software
can be tested for their performance within the network
though feedbacks taken from various users in organisation
in regular interval.
2. Switches and Routers used in the organisational network
helps in attaining performance dependability and stability
of the network (Mishra et al 2017).
Bandwidth It is very essential that all the devices in the network must have
equal and efficient bandwidth that can be achieved by using network
switches for connecting computers and devices together using
packet switching technique.
Access Control 1. Performance of LAN used in the organisation can be
influenced by the users who have the permission to access
file and file sharing among all the departments of the
organisation.
2. To enhance the performance of the organization in terms of
sales and profits ACLs or (access control list ) can be used
for both sales and marketing department.
Recommendations according to the above evaluation
1. To achieve effective performance of the network in the organisation it is recommended to
apply wired connection using Ethernet cables that will deliver quality service to the end
users within the network.
29

2. It is suggested to use wireless devices in the network which can be maintained easily and
cost effectively. And for optimising the performance of the network the higher authorities
of the organization can use monitoring tools that can also regulator the flow of traffic in
the network (Porras, et al 2015).
3. Within the organisation LAN is effective in covering a wide area with operational range
of bandwidth among all the connected devices that are interconnected by using wireless
networks.
4. The organisation can have a good network if it chooses to appoint stuff members who are
well skilled and qualified according to the technologies used within the organisation.
