Access
Access nodes are the demarcation point between the subscriber and the service provider network. They are Ethernet Layer 2 devices usually located in central offices, as part of outside plant, or in the basements of multitenant buildings and are owned and managed by the service provider. The access nodes provide different UNI options, subscriber and service multiplexing, and special functions for supporting triple-play services.

Aggregation
The Carrier Ethernet Aggregation Network is composed of aggregation and distribution nodes deployed in various physical topologies, most popular being rings and hub and spoke. The aggregation node provides an intermediate aggregation and multiplexing layer between the access and the edge network layers.
