摘要： The disclosure relates to a method for transmitting a message in a Hierarchical Layer 2 Virtual Private Network (H-L2VPN). A destination MAC address, to which a message is to be forwarded upon receiving the message, is determined by a first peer node of the network. The first peer node determines whether one or more equivalent pseudo wires (PWs) connected thereto form a path to the destination MAC address. When it is determined that more than one equivalent PW forms a path to the destination MAC address, an arbitrary equivalent PW is selected from the more than one equivalent PW by the first peer node. The first peer node sends the message, via the selected equivalent PW, to a second peer node of the network connected to the selected equivalent PW for forwarding to the destination MAC address.
摘要翻译：本公开涉及一种用于在分层二层虚拟专用网（H-L2VPN）中发送消息的方法。由接收到消息的消息将被转发到的目的地MAC地址由网络的第一对等节点确定。第一对等节点确定连接到其上的一个或多个等效伪线（PW）是否形成到目的地MAC地址的路径。当确定多于一个等效PW形成到目的地MAC地址的路径时，由第一对等节点从多于一个等效PW中选择任意等效的PW。第一对等节点通过所选择的等效PW将消息发送到连接到所选择的等效PW的网络的第二对等节点，以转发到目的地MAC地址。

摘要： When a User Edge Device (UED) receives a unicast packet from a user side, the UED searches in a Media Access Control (MAC) table. When a matching entry in the MAC table is found, the UED forwards the unicast packet locally. When no matching entry in the MAC table is found, the UED transmits the unicast packet to a Network Edge Device (NED). When the UED receives a broadcast packet from the user side, the UED broadcasts the broadcast packet within a same Virtual Local Area Network (VLAN) of a local site and forwards to the NED.
摘要翻译：当用户边缘设备（UED）从用户端接收单播数据包时，UED将在媒体访问控制（MAC）表中进行搜索。当发现MAC表中的匹配条目时，UED本地转发单播报文。当MAC表中没有匹配条目时，UED将单播包发送到网络边缘设备（NED）。当UED从用户侧收到广播报文时，UED将在本地站点的同一虚拟局域网（VLAN）内广播广播报文，并转发给NED。

摘要： The present disclosure describes reducing flooding of link state information of a link state protocol in a network with multiple routers. A filtering strategy is pre-configured on a router interface for filtering link state information generated by a first router. The filtering strategy is to enable link state database (LSDB) isolation between a second router associated with the router interface and the first router. Link state information generated by the first router is received or sent according to the pre-configured filtering strategy via the router interface.

摘要： The present invention provides an apparatus and method for processing a packet. An interface processing module selects one from all service processing modules as a service processing module for processing a packet; if the service processing module needs to perform tunnel processing for the packet, the service processing module transmits the packet after performing the tunnel processing; if another service processing module needs to perform tunnel processing for the packet, the service processing module transmits the packet to a service processing module needing to perform tunnel processing for the packet. According to the present invention, the packet can be processed uniformly by the service processing module, so it is not unnecessary to store session states in the service processing modules, and also not unnecessary to perform synchronization between the service processing modules, which greatly decreases complexity of processing the packet and saves system bandwidth.

摘要： A method for allocating VLAN resources, an FCoE device and an FCoE system. A first device maps a virtual storage area network identity (VSAN ID) corresponding to a fiber channel (FC) message into a media access control (MAC) address according to a preset relation. The first device obtains a VLAN ID corresponding to the VSAN ID according to the preset relation and encapsulates the MAC address and the VLAN ID into an Ethernet message corresponding to the FC message. The preset relation is used for mapping multiple VSAN IDs, which correspond to the same VLAN ID, into different MAC addresses.
