What Is A Function Of The Distribution Layer?

What is the function of the distribution layer?

• Connectivity for the high-speed backbone.
• In the wiring closets, it works by interconnecting the large-scale network.
• With the network user, it can provide network access.
• Fault isolation.

Answer: The distribution layer acts by interacting in the access and the core layer with the process of aggregation of an access layer connection in the wiring closets, giving the routing and switching, and applying the access policies with the rest of the network. The fault isolation and the high-speed backbone connectivity are the work of the core layer. The main goal of the access layer is to provide them access to the users.

Some of the distribution layer functionality is defined in the following:

• The distribution layer has the control access of the resources which are present at the core layer and also uses the bandwidth with efficiency.
• It can aggerate the wiring closet bandwidth by focusing on the low-speed access layer link into the high-speed core layer link and with the help of it can segment the workgroups and separate the problem related to the network to prevent an attack on the core layer.
• It gives redundancy in the connection for access devices, which helps balance the load between the devices.
• It acts as the routing boundary of the core and access layer which is the point for routing and packet manipulation.
• It can able to terminate the VLANs of the access layer, which took place on the access layer.
• It is responsible to give the media transition if any event occurs.
• It can work by summarizing the access layer routes to enhance the performance of the routing protocols, in some networks it can provide the default route to the access layer routers and for the core layer, it can run the dynamic protocol for communication.
