Foil 3 Network Designing Process (1)

From Network Design for Internetworking Lectures at Xi'an Jaotong University -- Sept 1998. by Roman Markowski
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
