Introducing Network Design Concepts
Network Requirements
Fast recovery
Application response time
Ease of management
Fast troubleshooting
Four fundamental network design goals
Availability
Security
Scalability
Manageability
Steps in network design projects
Characterize existing network
Design network topology & solutions
Identify network requirements
Design the Network Core Layer
High-speed & aggregate links
Redundancy & load balancing
Quick convergence
Full mesh topology
Combine routing & switching in same device
Partial mesh topology
Goals of the core layer
Failure prevention
Network backbone
Reducing human error
Core layer
connect distribution layer
Distribution Layer
interconnects smaller LANs
Access layer
give connections for hosts and end devices
Design the Distribution Layer of Network
Routing between VLANs
Redundant links improve network reliabilty & stabilty
Isolating core layer from access layer failure
ACLs filter traffic for security & management
Route summarization
Concept of route summarization & describe how it implemented at distribution layer of network
Access control policies
Filtering & managing traffic flow
Design the Access Layer of Network
Naming structures
VLAN architecture
Availabilty
Traffic patterns
Converged networking
Prioritization strategies
Wiring closets
Star topologies
Star
Fully-meshed
Physical location of equiment
Qos at network edge
Classfication
Assigned priority
Functions of VLANs
Control broadcasts
Single wiring closet
Separate & classify traffic
Factors Affect the Implementation of VPNs
Security
Remote access
Qos
Interconnections options
Traditional WAN technologies
Newer WAN technologies
Cost of bandwidth
