Define Network Strategy and Infrastructure

Use

To define the overall network infrastructure, including the design of:

·         Wide area network (WAN)

·         Local area network (LAN)

·         Data center network

Prerequisites

Technical design and solution deployment plan

Procedure

1.       Review the following requirements:

-         Geographical locations

-         Load

-         Number of users

-         Types of application (load characteristics of each application)

-         Printing volumes

-         Types of connectivity (wireless, mobile, Internet, satellite)

-         Security

2.       Define the overall network architecture.

3.       For each geographical location, define:

-         Capacity of the lines required

-         LAN requirements

4.       Define the routers and firewalls necessary for interconnection and segregation of traffic.

5.       Define the network infrastructure required for the data center.

6.       Define the detailed configuration necessary to support the solution, for example:

-         Routing protocols

-         Firewall ports

-         Virtual LAN

-         Proxies

-         Virtual Private Network (VPN) setup and dial-up setup
