         Applicability of the Access Node Control Mechanism to
      Broadband Networks Based on Passive Optical Networks (PONs)

Abstract

   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.
