MNET MN610: High-Level Design for SME Network and VPN Services

This document provides a VPN network design solution tailored for Small and Medium Enterprises (SMEs), addressing aspects like network requirements, security features, and VPN service implementation. It covers the need for VPNs, key components such as tunneling, encryption, and authentication, and discusses different tunneling protocols like PPTP, L2TP, and IPsec. The design incorporates a hub and spoke topology suitable for managing traffic between remote sites and the main network. Furthermore, the document outlines the implementation process to establish a secure connection, reduce costs, and improve productivity. It also includes references to relevant research and publications.

Introduction
 The presentation deals with establishing a
connection with all the departments of SME.
 Redundant link is needed for understanding
the response of network failover

Scope and requirements
The ultimate scope is understanding the developing
the project
 To implement new device and equipment in the
current organization and so that overall cost of
network can be easily reduced.
 Proper configuration of network services and
routing devices which is according to the
requirement of the given organization.
 WAP (Wireless access point) should be there
which is needed for various devices from the
client request

Requirements
The need of development of network solution can
be differentiated into various factors like service,
network requirement and lastly security.
 The network solution should be created for
understanding quality of standard for each and
every device in the network.
 The server needs to be kept in a separate room
under the lock so that it can be restricted from
any kind of physical access.

Need of VPN
 With the help of VPN a
complete isolated network is
established
 It builds up own TCP/IP
internet
 Leased Lines.
 It is much costlier
 It is isolated from the outside
world

Parts of VPN
Requirement of virtual private
network
 Tunneling
 Encryption
 Encapsulation
 Authentication
 Firewall

Types of Tunneling
There are mainly two types of tunneling
protocol that is
 Voluntary
 Compulsory

VPN tunneling protocol
VPN tunneling protocol comes up with layer
protocol that is
 Point to point Tunneling protocol (PPTP)
 Layer two tunneling protocol (L2TP)
 Internet protocol security (Ipsec)

Hub and scope
 This topology is the most simple way which
allow the employees to remote sites for accessing
the main network
 It is suitable for large number of traffic which is
needed by remote site and there is minimum
traffic between the sites

VPN service implementation
A VPN can be easily implemented for
establishing secure connection between VPN
tunnel and organization network.
 Reducing the overall cost
 Reducing the time for transmission of
remote user
 Improving the productivity

Conclusion
 From the above presentation it can be stated that proper network solution can be
generated by the checking the requirements of medium size organization. A list of
equipment has been provided which is needed for design of this network.
