1.2 critically analyse traffic intensive services and their performance
QoS of LAN Network:
QoS service is implemented on the Data link layer. It managed the network bandwidth and
traffic prioritization because it helped to reduce network delay. Scheduling, Cost of Service,
marking Classification, and policing, are the QoS service factor that is also managed Network
Delay.
Implementation of QoS:
IP precedence: it gives the precedence of the network service. For the service precedence, it
used 3-bit binary number representation. Higher priority services are configured in the
network.

1.3 discuss LAN concerns and make recommendations to sustain
network security, reliability and performance
Latency, Throughput, Packet Loss, Bandwidth, and Jitter are the main element that
procedures LAN Performance.
Latency: Latency noted the Network put off which impacts the performance of Network.
Latency normally computes in the msec so it commonly 10ms -20ms inside the given LAN
Network. Round trip delays are used in the Two-way communication within the TCP/ IP
Network because acknowledgement sign is needed for the source.
Bandwidth: It influences the Network overall performance. Data traffic and data flow are
managed by the network Bandwidth that reduced network issue and price. In the network,
there is occurred the bottlenecks problem which reduced the performance of the network.
PRTG bandwidth is used for the long-standing result in the network.
Jitter: it computes the time variance of packets between arrival times and inters time. In
the network, Jitters issue arise due to VoIP and Voice load traffic. It reduced the
performance of the network. LAN network supports the packet switched networks that are
needed for network communication. For the network communication, the network needs
TCP/IP Protocol which occurred the Jitter issue.
Packet Loss: it is measure factor which decreases the performance due to loss of packet
before receive at the destination place. Router performance, Faulty Cabling, Link
congestion, Device Software insects, Hardware, Firewall, switch, and hub are the reason for
the Packet Loss (Hurley,2014).
Throughputs: It is tested inside the community what a number of statistics packets are
obtained and sent inside the unique time durations. It checked the satisfactory packets
which might be received or sent. The window of TCP Congestion are impacted by
Throughput
Network Security: Firewalls, ACLs, and VLANs are an aspect for protection in the LAN
network.

the network, Jitters issue arise due to VoIP and Voice load traffic. It reduced the
performance of the network. LAN network supports the packet switched networks that are
needed for network communication. For the network communication, the network needs
TCP/IP Protocol which occurred the Jitter issue.
Packet Loss: it is measure factor which decreases the performance due to loss of packet
before receive at the destination place. Router performance, Faulty Cabling, Link
congestion, Device Software insects, Hardware, Firewall, switch, and hub are the reason for
the Packet Loss (Hurley,2014).
Throughputs: It is tested inside the community what a number of statistics packets are
obtained and sent inside the unique time durations. It checked the satisfactory packets
which might be received or sent. The window of TCP Congestion are impacted by
Throughput
Network Security: Firewalls, ACLs, and VLANs are an aspect for protection in the LAN
network.

4.2 resolve LAN issues to improve security, reliability and performance
Here I have explained the issue and their solution which faced during the network
implementation and testing. After the resolve these issues, it improved the network
performance, security, and reliability.
Configuration issue: during the network design, I have faced the system, resources, and
network Configuration issue. It is increased when given network size increased such second
floor and third-floor network design. Incorrect Configuration is decreased the network
performance and attracted the attacker which also affects the network security. I have used
the DHCP protocol, TCP/IP addressing schemes, and cabling approach for the proper
configuration of network and resource. Linksys router and configuring Windows are used for
testing of the network. OSI Model use to resolve the initial configuration and design issue in
the wired and wireless LAN Network.
Performance Issue: Network performance is depended on the delay, network design,
configuration of the network device, throughput, bandwidth, jitter, and data transmission
and interface. Latency and slow speed are decreased the network performance and data is
reached in the saturated condition. In the wired LAN network, I have used the gigabit
Ethernet between router, switch, and hosts. It increased the network speed. In the wireless
network, I have added interference in the network which enhanced the network
performance. I have used the packet analyser to analyse the network packet and their path.
It finds out the packet loss in the network with reason. It will help to resolve the packet loss
because it also affects the network performance.
Protocol Problems: I have faced the ISP-based protocol issues in the given network design
and development. Given LAN network needs IP addressing, DNS, and DHCP protocol with
the network TCP/IP. It faced the connectivity problem, communication problem, security
problem, and limited data transfer issue. These issues are resolved with help of IP
addressing, DNS, and DHCP protocol implementation on the network layer. And gives the
proper communication and connectivity is the network (Shimonski, 2009).

In the network, Packet Tracer associated to a remote Multiuser peer so there will be not
able to enable the Simulation Mode. For the enabling, Simulation Mode, there is need to
encourage the storage an offline copy (Juniper, 2018).
The Reset Simulation button disappears whole events in the Event List. when clicks on the
simulation, it is able to monitoring packets (self-created), QoS Stamp, delays packets, and
their type fields. It creates an event list. With the help of Edit Filters button, the user will be
able to see the hidden packet. Edit Filters contains an ACL Filter menu which holds Delete
an ACL Filter, Delete an ACL Filter, and submit an ACL Filter.
