Adatum Network Project: Hierarchical Network Planning & Implementation

This project focuses on planning and implementing a network solution for Adatum, aiming to control operational costs, prevent issues, enhance security, and ensure high network availability. The proposed solution involves a hierarchical network design consisting of core, distribution, and access layers. The core layer provides high-speed connectivity, the distribution layer manages traffic and enforces access control, and the access layer handles user access to internetwork resources. The project methodology includes initiation, planning, execution, testing, and closure phases. References to relevant research articles support the design and implementation strategies.

PLANNING AND IMPLEMENTING

Purpose of the project
• Control the operational cost: Reduces the
overall cost for Adatum.
• Issue prevention and active network
maintenance: Fix any issue immediately
• Security: provides security to the
organization by securing the sensitive
data
• High network availability: enhance the
business operation

Project Requirements
•Faster speed
•Pre define the countermeasures of the network
infrastructure
•Secured
•Should be easily modified according to the
updates
•Should have an ability to fix normal errors

Proposed
solution
Hierarchical
Network: Core
layer, distribution
layer and access
layer

Proposed solution
(contd.)
Core layer: The switches and the
routers in this layer give high speed
connectivity. In an organization the
core layer can connect multiple
buildings and also give connectivity
to server farm. The core layer
consists of VPN, extranet, WAN. It
enhances the network development
(Li & Pan, 2013). The technologies in
the core layer are high speed,
aggregate links, enhancing routing
protocols and load balancing.

Proposed solution
(contd.)
Distribution layer: This layer deals
with filtering, communication point
and filtering between the access
layer and the core layer. The main
functions of this layer are filtering
as well as handling the traffic flows,
summarizing the routes before the
advertisement of the routes to Core,
Enforcing the access control policy
and isolating core from the access
layer disruptions (Liu et al., 2017).

Proposed solution
(contd.)
Access layer: It is utilized to
handle user access regarding
the internetwork resources.
Network designer facilitate
traffic that is produced from
access layer. The end devices
are connected here. The access
layer resides in the campus
building, server farm and at the
edge of the company (Du, Wang
& Wang, 2015).

Cisco Enterprise
Architectures
Three-layer hierarchical design will
be further divided in modules. Each
module defines various logical or
physical connectivity
Three areas of the modular network
design are:
Enterprise Campus, Enterprise Edge and
Server farm.

Methodology
The project will be completed
in five different phases
Project initiation
Project planning
Project Execution
Project Testing
Project Closure
