Mapping MEF Terminologies to Network Technologies

The MEF terminology only describes the outside characteristics of a service, that is, what the service
looks like from the perspective of a customer looking in towards the user-to-network-interface (UNI)
device. It does not describe how the service is implemented.

For details about how these service are implemented, see the following URL:

http://www.cisco.com/go/ce

In particular, see the documentation on that site on the subject of Cisco IP Next-Generation Network
(NGN) Carrier Ethernet Design. The IP NGN Carrier Ethernet Design represents key elements of the
Cisco IP NGN architecture that enable a best-in-class implementation for consistent service delivery
optimized to meet the specific demands of each service. It is the end-to-end service transport foundation
from the network access to the IP/MPLS core. This design provides integrated linkages with the service
and application layer components to offer a converged, intelligent, reliable, and scalable network model
to meet current and future network service requirements.

The IP NGN Carrier Ethernet Design (see

Figure E-1

) provides a platform-independent architecture and

Ethernet-based services model across all Carrier Ethernet platforms. This allows service providers to
optimize service transport with the intelligence of appropriate networking technologies (such as
Ethernet, IP, MPLS, multicast, pseudowire, or hierarchical private virtual LAN services) to meet their
business and quality-of-experience goals.

Note

Real-world network implementations may implement only a subset of this very scalable architecture.
