Aggregation networks refer to their network infrastructures which are the link between the access networks whose data transfer they aggregate, and the operators’ core network which processes and redirects these flows. On an even larger scale, the large fibre highways connect the different networks and connection areas between regions and between countries. This poster is a bit more complex as it tries to explain, beyond the hardware, some of the processes involved in the aggregation networks and cores for data (request, etc.) to be correctly routed.
