Description
User-facing
provider edge (U-
PE)
A supplier routing device that connects to the router of a customer edge
(CE), which is an OLT in this document. The U-PE supports routing and
Multiprotocol Label Switching (MPLS) encapsulation. If a U-PE
connects to multiple CEs, the U-PE supports basic bridging functions.
In this case, the U-PE forwards data frames, which reduces the load of
switching provider edges (S-PEs).
Aggregation
provider edge (PE-
AGG)
An aggregation router, which provides aggregation and route
forwarding functions for access devices. Compared with U-PEs, PE-
AGGs provides fewer ports and higher performance and switching rates.
NGN or IP
multimedia
subsystem (IMS)
A type of network that centers around softswitches and uses an open and
standardized architecture. It provides voice, video, and data services.
A type of system that uses Session Initiation Protocol (SIP) signaling as
its call control signaling. It provides voice, data, and multimedia
services.
NOTE
In this document, the NGN or IMS is the softswitch that supports H.248 or SIP.
IPTV head end
A contents preparation platform in the IPTV system. It receives signals,
converts media formats, and manages media materials.
