This is an example of a network with Service DIF. Service DIF are DIFs that provide IPC services end-to-end over the whole scope of the service provider network, as an ISP would normally do. They allow customers to access "utility DIFs", such as a public Internet DIF, VPN DIFs independent of the used access technology. They can also be used to hide mobility of clients within the scope of the service provider network (and from the "utility DIFs").

In this Service DIF network, a Residential Service DIF is placed between the network and two utility DIFs called VPN and Internet. The access network is modelled as a wireless network (Wireless Network_ with an AP and a STA node). Access could also provided via a fixed technology, such as DSL.

The aggregation of access traffic is realised by a MAN Service DIF towards an edge service router. The provider’s core network then is a Backbone DIF supported by a PE service routers (2 in this example). Residential Service carries the traffic of VPN and Internet up to the PE router.
