For the purposes of the present document, the terms and definitions given in TR 21.905
and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905
A function which provides NAT44, NAPT44, NAT64, NAPT64 or combinations of these.
as used by RFC 4364 , term to refer generally to means of attaching to a router, such as: PPP connections, ATM Virtual Circuits (VCs), Frame Relay VCs, Ethernet interfaces, Virtual Local Area Networks (VLANs) on Ethernet interfaces, GRE tunnels, Layer 2 Tunnelling Protocol (L2TP) tunnels, IPSec tunnels, etc. An attachment circuit identifies uniquely the MPLS VPN used by all traffic using that circuit.
as used by RFC 4364 , stands for Customer Edge router or Customer Edge device. It represents an IP device using a BGP/MPLS IP Virtual Private Networks (VPN) to communicate with other CE devices using the same VPN, without the need to be routing peers of each other and without visibility of MPLS or the MPLS backbone providing connectivity between CEs in different sites. CEs are connected to PEs using attachment circuits. If CEs use dynamic routing protocols (CE routers) to route traffic in the VPN, then they are routing peers of the directly attached PEs.
as used by RFC 4364 , stands for Provider Edge router. PEs use MPLS to tunnel traffic among each other enabling IP traffic between the CEs attached to them.
