Benefits of technology

The invention simplifies the configuration of the ONT and makes it easier to add new functions. This means that some of the functions of a conventional ONT are being performed by the OLT.

Problems solved by technology

Network managers already familiarized with copper LANs have difficulties in managing of optical LAN composed of optical line terminals (OLTs) connected to a plurality of optical network terminals (ONTs) over a passive optical network (PON) due to different standards and management types.

Abstract

Disclosed is a new advance in a network management function of an optical time terminal (OLT). A virtual switch management program is running on the disclosed OLT. The virtual switch management program provides a switch management environment for a single chassis-based Ethernet switch with a plurality of port extender cards corresponding to the optical network terminals and being mounted thereon through a management terminal. The virtual switch management program receives a switch management command for each port extender through the management terminal and outputs a fiber LAN management command corresponding to the switch management command to an optical network terminal corresponding to each port extender.

Description

BACKGROUND1. Field[0001]Embodiments of the present disclosure relate to a new development in a network management function of a fiber local area network (LAN) system, and more particularly, to an optical line terminal (OLT).2. Discussion of Related Art[0002]U.S. Pat. No. 6,567,403, published on May 20, 2003, proposes a single virtual chassis switch network topology. Virtual chassis technology allows for managing of switches connected to one another in a tree structure, like a switch having one expandable port.[0003]In place of such copper LAN, optical LAN technology is being increasingly employed. U.S. Pat. No. 8,406,627, published on May 26, 2013, discloses a technique for stacking an optical network terminal (ONT) connected to an optical line terminal (OLT). An ONT management and control interface (OMCI) protocol, which is a standard management protocol of a passive optical network (PON) includes a data model that describes elements associated with a chassis-based ONT, for example...
