Network Designing Process (1)
Designing or upgrading a network is a difficult task
- network can be constructed in many different ways
- redundancy: Can your network afford downtime ?
- scalability, management, traffic monitoring, bottleneck identification
Hierarchical model: a central cloud interconnects campus backbones,which in turn link up building and departmental networks
- scalable bandwidth alone does not solve networking problems
- mission critical applications
- Quality of Service: priority to time-sensitive data while still delivering lower-priority traffic
