Local Area Network Design and IP Addressing Plan Presentation

This presentation outlines a network design and IP addressing plan developed for MyNetworks Company, focusing on an extended star topology to enhance redundancy and eliminate single points of failure. The LAN design incorporates separate switches for each floor or department, with a central switch configured as a VTP server to distribute VLAN information. Two layer 3 switches are used for redundancy. The presentation includes a detailed IP addressing scheme, hardware requirements, and server specifications for email and web services. The design aims to improve network scalability, performance, and provide consistent performance across all user locations, accommodating future growth and expansion of the organization. The document is available on Desklib, a platform providing AI-based study tools for students.

Introduction
 The presentation is prepared for MyNetworks Company for the
development of a local area network design and IP addressing plan.
The building floor plan of the organization and the number of
departments and the location of each of the department is analyzed
for the development of then network design. The application used by
each of the department and the requirement of bandwidth for
increasing the efficiency of the network is estimated such that
response time of the network is reducing and congestion, packet loss
and jitter can also be reducing and thus improving the network
performance.

Network Topology
 Extended star network topology is selected for the development of
the network solution for MyNetworks Company. In the basic star
topology, the nodes are connected to a central network hardware
device and it can be hubs/ switch creating a point to point connection
for forming the physical network segment. Here the switch acts as
the server for the computer devices connected to it are entrusted on
it because it is the main point for exchange of information (Moin et al.
2017). It has some negative and positive effects on the network
solution and the extended star topology is used for increasing the
redundancy of the network device and eliminate the dependency on
the central device by creating multiple redundant path for reaching
the destination address in the lo0cal area network.

LAN Design
 The local area network design is created after analyzing the building
floor plan of the company and for each of the floor or the department
a separate switch is used. The central switch connected with the
router interface is configured as VTP server and the VLANs are
configured in the switch. The other switches are configured as VTP
client such that the VLAN information are automatically distributed to
each of the network device. The two layer 3 switch are used for
increasing the redundancy and eliminating the risk of failure of single
device.

Conclusion
 From the above presentation it can be concluded that the developed
network design for MyNetworks Company is efficient and the
extended star topology would help the organization to expand the
network with its growth. The network is designed for increasing the
scalability and performance of the network and provide equal
performance to all the users connected in each of the floor of the
building. The local area network design is created for each of the floor
of the building and the departments. The number of IP address
needed for each of the department is estimated for the development
of the IP addressing and plan and some of the extra number of IP
address are left for each of the subnet such that the network can
support the future expansion and growth of the organization.
