Horizontal view
This horizontal view of the Internet can be divided into two main parts:
Network edge
The part of the network closest to the final users. Ranging from residential access to mobile access networks. Heterogeneous devices. An Internet Service Provider (ISP) usually provides these networks.

Network core
Composed of the innards of the Internet, usually “hidden” from the end user. This consists mainly of a mesh of interconnected routers. Homogeneous devices. ISPs need to coordinate among them to forward packets crossing different domains.
