Designing and Supporting Computer Networks
Network requirement
Fast recovery
Application response time
Ease of management
Fast troubleshooting
Four fundamental network design goals
Availability
Security
Scalability
Manageability
network layer
core layer
connect distribution layer devices
access layer
provides connections for end devices
distribution layer
interconnect smaller LANs
subdividing the three-layer model into modular areas
server farm
enterprise edge
enterprise campus
Advanteges of Modular Framework
it eases the design task by making each module independent
it creates a deterministic network with clearly defined boundaries between modules
goals of the core layer
maximize throughput
faciliate network growth
provide 100% uptime
step in network design project
characterize the existing network
design the network topology and solutions
identify the network requirements
function of Vlans
control broadcasts
contain VLANs within a single wiring closet
separate and classify traffic
security risks at the network edge
Authentication
wireless security
Security meansures at the access layer
strong password
Disabling unused ports
pysical security
seurity policy
Describe the benefits and security implication of creating server farms
redundant,high-capacity links
load balancing and failover
defined entry and exit pont for network traffic
lower cost of providing services
customer requirement
authentication
services and applications
roaming
coverage and number of users
descibe the considerations of an implementation of a wireless network design
site survey
logical WLAN design
physical WLAN design
