Enterprise Campus Network
Typical Requirements for an Enterprise Campus Network Functionality Performance Scalability Availability Manageability Cost-effectiveness
Importance of Campus Infrastructure Modules Based on Design Criteria
Enterprise Campus Design Methodology Used in This Course Determine application and data requirements. Design the logical network. Design the physical network. Select specific Cisco network devices at each location and create a network topology diagram. Select an IP addressing strategy and numbering scheme. Select routing protocols. Design the Edge Distribution module.
Example: Characterizing Applications
Factors to Consider When Analyzing Traffic Traffic load measurements kbps per active user kbps per active segment Average and peak loads Traffic types Data Voice Video Sampling methods Weekdays versus weekends Holidays Type of traffic (data, voice, video) Apparent versus offered load Sample period Total number of samples taken Stability of the sample period
Summary To design an enterprise campus network, you will design the Campus Infrastructure, Network Management, Server Farm, and Edge Distribution modules. An enterprise campus network must meet requirements for performance, scalability, and availability, as well as for functionality, cost-effectiveness, and manageability. Cisco’s network designers have developed a simple process to design an enterprise campus network. Before designing the actual network, you should analyze the network traffic patterns for each application and location on the network. You will use the information to design the logical and physical network.
