Explanation:
It is ideal for small companies: The collapsed core model is a reduced version of the three-tier model. The deduction was made to create a network for small and medium-sized campuses. Therefore, smaller institutions can get the advantage of using a collapsed core network while still gaining the same benefits they would if they were using a three-tier model. Small organizations often cannot afford the hardware and human resources to run the network can benefit greatly with less oversight necessary.
And reduces cost: In a traditional three-tier campus network, the core layer is typically a complex and expensive piece of hardware. This layer is eliminated with collapsed core architecture, reducing both cost and complexity.
