Describing the Campus Infrastructure Module
Enterprise Composite Network model benefits

To scale the hierarchical model, Cisco introduced the Enterprise Composite Network model, which further divides the enterprise network into physical, logical, and functional boundaries. The Enterprise Composite Network model contains functional areas, each of which having its own Building Access, Building Distribution, and Building Core layers.

The Enterprise Composite Network model meets these criteria:

  • It defines a deterministic network with clearly defined boundaries between modules. The model also has clear demarcation points, so that the designer knows exactly where traffic is located.
  • It increases network scalability and eases the design task by making each module discrete.
  • It provides scalability by allowing enterprises to add modules easily. As network complexity grows, designers can add new functional modules.
  • It offers more network integrity in network design, allowing the designer to add services and solutions without changing the underlying network design.

Benefits of the Enterprise Composite Model
The Enterprise Composite Model has a number of benefits for each of the submodules where it is implemented.
