Presentation on Enterprise Network Design

This presentation discusses the network design and implementation process for a financial and insurance firm. It covers topics such as network layout design, network implementation using Packet Tracer, scope of the network, subnetting and IP addressing.

Network Design and Implementation
of the firm

Network Implementation
 The process of implementing the network infrastructure of the financial
and Insurance firm involves setting up the network according to the
design using packet tracer.
 This involves demonstrating wired connections with the network
equipment and devices among various departments of the firm as well
as wireless communication and connection with ISP.
 Additionally the network needs to demonstrate connections to database
server, Ethernet printer and LAN connection between the departments.

Network Layout Design

Physical Network Topology (Packet
Tracer)

Scope of Network
 The network connection acquired through the ISPs is screened through a
firewall device before reaching switches of respective departments.
 The intention of placing the firewall here is to manage network connections
in the LAN network consisting of the five departments [1].
 Only the Manager from Management and Employees is to be able to
connect with the finance department which should not have internet
access.
 Therefore network connection should be configured but internet services
and communication of other departments should be blocked by the firewall
 Wireless communications should be available through a separate network
using a wireless router

Other relevant aspects involve
configuration of the routers and
network devices with IP addresses.
IP Address allocation has been listed
for devices of all the five
departments and the interfaces of
the routers [3].
The major network chosen for the
subnet calculation is
172.16.121.0/24
The IP addressing method used for
the following IP addressing is
Classless Inter-domain Routing
(CIDR) [2].
CIDR is chosen against classful IP
addressing scheme for efficient
allocation of IPs.

Conclusion
 The presentation identifies the requirements and successfully provides
the solutions for the network layout of the financial and insurance firm.
 The network is implemented using Packet Tracer and the IP addresses
for the respective devices and network equipment are configured.
 The IP address allocation process also gets explained along with the IP
addressing method used.
