Applicability of the Access Node Control Mechanism to Broadband Networks Based on Passive Optical Networks (PONs)
2013
The purpose of this document is to provide applicability of the Access
Node Control Mechanism to broadband access based on Passive Optical
Networks (PONs). The need for an Access Node Control Mechanism between
a Network Access Server (NAS) and an Access Node Complex, composed of
a combination of Optical Line Termination (OLT) and Optical Network
Termination (ONT) elements, is described in a multi-service reference
architecture in order to perform QoS-related, service-related, and
subscriber-related operations. The Access Node Control Mechanism is
also extended for interaction between components of the Access Node
Complex (OLT and ONT). The Access Node Control Mechanism will ensure
that the transmission of information between the NAS and Access Node
Complex (ANX) and between the OLT and ONT within an ANX does not need
to go through distinct element managers but rather uses direct device-
to-device communication and stays on net. This allows for performing
access-link-related operations within those network elements to meet
performance objectives.
