Problems solved by technology

In addition, due to the maturity of the optical distribution network (ODN) that connects the OLT to the traditional ONU, and fixed office points, the cost of SDN / NFV transformation is high. Therefore, the PON network cannot be simply replaced by OVS
In other words, traditional ONU management still has strong vitality even in SDN / NFV networks

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0035]The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0036] According to the G984.3 standard, the ONU control and management level has three parts: embedded (operation management and maintenance OAM, Operation Administration and Maintenance), physical layer OAM (PLOAM) and OMCI. OMCI is one of them, and it p...

Abstract

The invention discloses an SDN (Software Defined Network) / NFV (Network Function Virtualization) open access network system, which comprises a virtual optical line terminal (vOLT), access network equipment with an Openflow switching capacity and ONUs (Optical Network Units) / ONTs (Optical Network Terminals), wherein the vOLT is interconnected with the access network equipment through an Openflow switching network; and the access network equipment is interconnected with the ONUs / ONTs through an optical distribution network (ODN. The invention further discloses an ONU / ONT management method of the SDN / NFV open access network system. According to the invention, an OVS (Openflow Virtual Switch) network of the SDN is combined with traditional ONU / ONT management, the original ODN network architecture is sufficiently utilized, and the management process of configuring, maintaining and updating the ONUs / ONTs of an SDN controller is simplified.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an SDN / NFV open access network system and a method for managing ONU / ONT. Background technique [0002] In the traditional access network, the network management system (EMS, Element Management System) is connected with the optical line terminal (OLT, Optical Line Terminal), which can provide the optical network unit management control interface (OMCI, ONU Management and Control Interface) management graphical interface. As a new type of network architecture, Software Defined Network (SDN) builds an open and programmable network architecture by decoupling network control and network forwarding. SDN abstracts the network to shield the underlying complexity, and provides simple and efficient configuration and management for the network. For the access network, the network above the OLT of the access network will face the increasingly widespread trend of SDN / Network Function...
