This presentation aims to show…





…The different networks, technologies and players involved in the overlay traffic transport …The current existing options for ISP interconnection – Peering and transit – SLAs – Charging schemes




…What are the main issues in overlay traffic management – QoS differentiation – Locality




… What technical incentives may be offered by the network operator in order to promote the traffic locality

Wireline and wireless access 6

Aggregation (Ethernet)

The IP edge router (BRAS) inspects users’ packets in order to check their destination address.

GPON FTTH Bandwidth per user

50 Mbps downstream/ 10 Mbps upstream

Dynamic Bandwidth Allocation

Yes (defined in G.984.3)

Maximum delay between two users connected to the same OLT QoS control
