VNF Forwarding Graph
Network Forwarding
Path(NFP)
NFP is an ordered list of connection
points that form a network-service
chain along with attached policies for
each connection-point.
Virtual Link (VL)
The VLD describes the basic topology
of the connectivity (e.g. ELAN, ELINE,
ETREE) between one or more VNFs
connected to this VL, bandwidth and
QoS class, IP address and VLAN
allocation), and additional information
(e.g. location, anti-affinity rules etc.).

The VLD describes the basic topology of the connectivity (e.g. ELAN, ELINE, ETREE) between one or more VNFs connected to this VL, the
required parameters for each interface (e.g. bandwidth and QoS class, IP address and VLAN allocation)
