Advanced Network Design for a Lawyer Firm

This document provides a detailed network design and justification for a lawyer firm with an IP addressing plan, router configuration, and timeline and budget estimation. The network is designed with multiple redundancy and star topology for interconnecting the switches and other network devices. Each department is allocated with a separate VLAN and the layer three switch is configured with access control list for meeting the service requirement of the law firm. The document also includes a timeline and budget estimation for the project.

ADVANCED NETWORK DESIGN
Project Scope and requirement
There is a requirement of development of a network solution for a lawyer firm having 6
departments according to their service requirement. The scope of the project is to analyse the
technology and the network topology that can be used for the development of the network such tat
the performance of the employees can be improved and their activity can be managed. The scope of
the project is identified for the identification of the hardware needed for the development of the
network solution and creating a timeline and budget for the project. For the development of the
network each of the department is allocated with a separate VLAN and the layer three switch is
configured with access control list for meeting the service requirement of the law firm.
Network Design and Justification
The network is designed with multiple redundancy such that the uptime of the network is
improved and for each of the department separate switches. Star topology is used for
interconnecting the switches and the other network devices. The selection of the star topology
improves the performance of the network and new nodes can be connected in the network easily.
The core switch is configured with VTP server such that there is a centralized management on the
network and failure of one of the link does not have effect on the whole network. The application of
the star topology helps in enabling the uses to get access to the resources such as printers and
servers easily and there is minimal disruption in the network. The following IP addressing scheme is
developed for allocating the IP address to each of the VLAN and configure the network following the
needs of the law firm.

Access point and server configuration guidelines
The access point installed for each of the department should be configured such that it does
not serve large number of users connected in the network. The access point should also be
configured such that it configuration should be protected from the external users. 802.1
authentication is used for authentication of the client device and the servers should be regularly
backup such that no data is lost in case of network failure. The access point should be configured for
providing connection to 50 wireless client and it should be performed at a rate of 5 authentication
for each second. The user connecting with the access point and server should be locked for a specific

time period in case of inputting incorrect password and the unblocking should be done manually for
increasing the security of the network.
