What does a collapsed backbone typically reduce in network architecture?

A collapsed backbone architecture is designed to combine the core and distribution layers of the network into a single layer. This design typically reduces both cost and complexity in the following ways:

1. Cost: By integrating functions traditionally handled by separate layers into one, the need for additional networking equipment (like switches and routers) is diminished, leading to lower hardware costs. Maintenance and operational costs are also reduced as fewer devices mean reduced power, cooling, and space requirements.

2. Complexity: Simplifying the network structure reduces the number of devices and interconnections, which can complicate management and troubleshooting. A less complex architecture allows for easier configuration, monitoring, and overall management of the network.

In this way, a collapsed backbone effectively streamlines the network architecture, making it more efficient and cost-effective for organizations to implement and manage.
