Integrated management of 10G-PON network element using NETCONF and OpenFlow

Abstract

This paper describes an integrated management architecture and solution for controlling network elements composed of controller, optional aggregation switch and a variable number of optical line terminals (OLTs), including multiple OLTs based on different technologies and presenting distinct features. The YANG language was used to model configuration and state data manipulated by the Network Configuration Protocol (NETCONF). The system allows the configuration of OpenFlow switches, providing greater protocol flexibility and forwarding algorithms to the aggregation network. The architecture has been implemented and tested using a real Gigabit-capable Passive Optical Network (GPON), a stacked GPON and switch equipment in a variety of scenarios.
