Abstract: PURPOSE: A method of setting an expanded label switching path in an MPLS(Multi Protocol Label Switching) system is provided to set an expanded label switching path up to an MPLS area from a forwarding engine mounted in a specific port of an ATM exchange, thereby improving a system performance. CONSTITUTION: An MPLS LER(Label Edge Router) sets a label switched path(401). In an MPLS area, a label switched path setup is performed by a label distribution protocol. When the label switched path is set, the MPLS LER decides an operation mode of the set path(402). If the operation mode operates in an ingress mode, the MPLS LER confirms whether a preset subscriber PVC is connected(406). If so, the MPLS LER registers a forwarding entry for an ingress connection(407), and transmits the registered forwarding entry to a forwarding engine(408).
Abstract translation: 目的：提供一种在MPLS（多协议标签交换）系统中设置扩展标签交换路径的方法，用于设置从安装在ATM交换机的特定端口中的转发引擎到MPLS区域的扩展标签交换路径，从而 提高系统性能。 构成：MPLS LER（标签边缘路由器）设置标签交换路径（401）。 在MPLS区域中，标签交换路径设置由标签分发协议执行。 当标签交换路径被设置时，MPLS LER决定设置路径的操作模式（402）。 如果操作模式在入口模式下操作，则MPLS LER确认是否连接了预设用户PVC（406）。 如果是，则MPLS LER为入口连接注册转发条目（407），并将注册的转发条目发送到转发引擎（408）。

Abstract: A GPON blade of an ATCA(Advanced Telecom Computer Architecture) system and a control message processing method are provided to manage a link and an ONT by monitoring an ONT(Optical Network Terminal) error and a GPON link error in real time. A GPON(Gigabit-capable Passive Optical Network) link device(16) is connected to respective GPON links, and transmits and receives a user traffic. A GMII(Gigabit Media Independent Interface) interface user traffic portion(14) delivers the user traffic between the GPON link device and an Ethernet switch. A control message processor(11) communicates a control message with an OAM(Operations, Administration and Maintenance) processor, processes a GPON link control message separately from an ONT management control message, and monitors a GPON link error and a protocol error. An OMCI protocol processor(12) analyzes an OMCI(ONT Management Control Interface) message from the control message. A GPON protocol command processor(13) processes a GPON protocol command and reports a GPON interrupt to the control message processor. A GPON link PLOAM(Physical Layer OAM) transceiver(15) delivers a PLOAM message among the GPON link devices, the OMCI protocol processor, and the GPON protocol processor.

Abstract: PURPOSE: A 2-layer multicast group managing method using IGMP packet information in an ethernet switch is provided to allow hosts, which do not support GMRP or GVRP, to register a desired 2-layer multicast group and virtual LAN by using an IGMP packet of an IP layer. CONSTITUTION: An ethernet switch makes an MAC look-up with a destination MAC address of a frame received from a port set in an access mode or in a hybrid mode(601,602). The ethernet switch determines whether a range of the destination MAC address corresponds to 01:00:5e:00:00:00-01:00:5e:7f:ff:ff(603). If it is determined to be an IGMP packet, the ethernet switch searches a mapped virtual LAN ID by searching a mapping table with the group address in the IGMP packet(605-607). It is determined whether a type field value in the IGMP packet relates to a group registration request or deletion(608). If the field value relates to the registration request, the ethernet switch generates a virtual LAN table entry(609,610).

Abstract: PURPOSE: An ATM(Asynchronous Transfer Mode) switch based switching and routing device having distributed FEs(Forwarding Engines) and a method thereof are provided to selectively add FEs for a port to be used for MPLS(MultiProtocol Label Switching) on a subscriber interface part of the ATM switch, so as to simultaneously handle ATM switching and IP(Internet Protocol) routing. CONSTITUTION: FEs(200) are distributed in each AIM(ATM Interface Module) to provide an IP service in an ATM switch. A port for providing an MPLS service is selected to install each FE(200) between a PHY(PHYsical layer) and the AIM.

An MPLS service controller(300) is installed in a control plain to provide the MPLS service in the ATM switch, thereby controlling each FE(200). And the MPLS service controller(300) controls each FE(200) to configure forwarding information and merging information for packets received in the EF(200).
