Abstract: PURPOSE: A virtual LAN management device in an E-PON(Ethernet-Passive Optical Network) system and a method thereof are provided to accord virtual LAN information managed by ONUs(Optical Network Units) with virtual LAN information managed by a single OLT(Optical Line Terminator), thereby effectively managing an entire network. CONSTITUTION: A virtual LAN setup/controller(110) analyzes a request command of a network operator, which is received from a command interface(400), and sets a virtual LAN for all ports of an OLT(210). A virtual LAN information manager(120) periodically updates, adds, or deletes information within a virtual LAN DB(130) to accord information with the set virtual LAN, and adds or deletes virtual LAN information of ONUs/ONTs(220).
Abstract translation: 目的：提供E-PON（以太网无源光网络）系统中的虚拟LAN管理装置及其方法，以使由ONU（光网络单元）管理的虚拟LAN信息与由单个OLT管理的虚拟LAN信息（光学 线路终端器），从而有效地管理整个网络。 构成：虚拟LAN设置/控制器（110）分析从命令接口（400）接收的网络运营商的请求命令，并为OLT（210）的所有端口设置虚拟LAN。 虚拟LAN信息管理器（120）周期性地更新，添加或删除虚拟LAN DB（130）内的信息，以与所设置的虚拟LAN相符合信息，并且添加或删除ONU / ONT（220）的虚拟LAN信息。

Abstract: 본 발명은 이더넷-폰(Ethernet-PON) 시스템에서의 가상 랜 관리 장치 및 그 방법에 관한 것이다.
본 발명에서는, 광 종단 장치(Optical Line Terminator)와 광 통신망 유니트(Optical Network Unit)를 포함하는 이더넷-폰(Ethernet-PON) 시스템에서의 가상 랜(LAN) 관리 장치에 있어서, 광 종단 장치의 포트에 가상 랜을 설정하는 가상랜 설정/제어부와, 설정한 가상 랜의 상태를 포함하는 가상 랜 정보를 주기적으로 갱신하며, 갱신한 가상 랜 정보와 광 통신망 유니트가 관리하는 단말기별 가상 랜 정보가 일치하지 않으면, 일치하지 않은 정보를 가진 광 통신망 유니트별 응답 여부에 따라 갱신한 가상 랜 정보를 전송하는 가상랜 정보 관리부를 포함한다. 이때, 가상랜 정보 관리부와 광 통신망 유니트는 레드-블랙 트리(Red-Black Tree) 알고리즘에 따라 가상 랜 정보를 주기적으로 갱신한다.

Abstract: PURPOSE: A method of operating and maintaining a network for managing plural EPONs(Ethernet Passive Optical Networks) and a device thereof are provided to define a standardized OAM information packet structure and processing method for transmitting OAM information, and to exchange the OAM information by using TCP/IP, thereby removing inefficiency of a system. CONSTITUTION: In a standby state(501), if an EMS(Element Management System) server operates to receive OAM information in IPC message type(502), a system analyzes a header of an IPC message(503). The system decides whether the IPC message is from an EMS client or from an EPON OAM block by using an SNI(Source Node Identifier) among information of the header(504). If the message is from the EMS client, the system branches to an A1. If the message is from the EPON OAM block, the system branches to an A2.
Abstract translation: 目的：提供一种操作和维护用于管理多个EPON（以太网无源光网络）的网络的方法及其设备，以定义用于发送OAM信息的标准化OAM信息分组结构和处理方法，以及通过使用 TCP / IP，从而消除系统的低效率。 构成：在备用状态（501）中，如果EMS（网元管理系统）服务器操作以接收IPC消息类型（502）中的OAM信息，则系统分析IPC消息的报头（503）。 系统通过使用报头（504）的信息中的SNI（源节点标识符）来判断IPC消息是来自EMS客户端还是来自EPON OAM块。 如果消息来自EMS客户端，则系统分支到A1。 如果消息来自EPON OAM块，则系统分支到A2。
