3. Introduction
Network design consists of
Description of (technology and topology)
Product details(product type, name
Device configurations (h/w & s/w )
Service selections(QoS, voIP - Voice over
Internet Protocol)
Vendor(supplier / seller / manufacture),
Location Information and
General structure (switches/routers)
Network functions( security, nw mngnt)
General locations (building, rooms, floors)
4. Analogy to a building design
In designing a building
The designer / architect needs to know
the general purpose for that building
Ex: what types of occupants such as
○ Residential
○ Commercial
○ Industrial
5. Analogy to a building design
The building design would include the
building’s physical layout
How space will be used,
How occupants will move around within the
building,
Their needs for building resources such as
○ HVAC, lighting, power, water, plumbing,
elevators, stairs, restrooms, fire safety,
exits(emergency exit), etc..
6. Analogy to a building design
The product of the building design is a
set of blueprints.
That provide a physical layout for all of
this information, and
Show the relationships among
components of the building such as
Trade-offs (space, power & other resources)
7. Design products
The key products of a network design
are:
Network blueprints
A component plan
Vendor
Vendor equipment
Service provider selection
Metrics for measuring design success.
8. Network blueprints : physical aspects of your
network design.
Network blue prints consists of
Single diagram
Several diagrams of the network. Its vary
depend on your needs and the size of your
project.
Locations of network devices
Servers
The cable plant.
9. Physical security and secure locations
How devices are interconnected.
Interface types and speeds.
If the network design is large, it has one
or more high level diagrams that show
the entire network.
ex:
LAN diagram (geographical areas)
WAN diagram (geographical areas)
10. A component plan which describes the
mechanisms associated with that
function.
Internal interactions
External interactions
12. Input to the design
These analysis and architecture
processes provide products that serve
input to our design.
Fig. shows the architecture products

products.
13. Design process
The design process consists of
Vendor
Equipment
Service provider
Network layout
Types of products:
○ Architecture products
○ Analysis products
15. Analysis products
Requirements
Flow information
Problem statements
Service information
Network layout :
logical diagram ,physical blueprints and
function component plans.
