In network design, the Main Distribution Frame (MDF) and Intermediate Distribution Frame (IDF) are
critical components of the network infrastructure. The MDF is the primary hub of the network, often
where services from outside the campus or building enter and get distributed. It acts as a central
point for network distribution. On the other hand, IDFs are secondary hubs situated throughout the
building or campus, extending connectivity provided by the MDF to various endpoints or areas within
the building. The simple difference between them lies in their roles within the network
infrastructure: the MDF serves as the main point of network ingress and egress, while IDFs are used
to further distribute the network to specific locations or floors within the building.
