Abstract: Embodiments of the present invention disclose a method, apparatus, and system for detecting performance of a layer 3 virtual private network. A first node creates an OAM instance according to OAM configuration information set by a user, and sends the OAM configuration information to a second nodet; the second node creates an OAM instance according to the OAM configuration information; and the first node performs OAM detection by sending an OAM packet to the second node and/or receiving an OAM packet from the second node, where the sending and/or receiving is implemented by using the OAM instance of the first node. According to the present invention, not only an OAM configuration procedure is simplified and manpower is saved, but also consistency of OAM configuration at two ends can be ensured. In addition, a configuration delay in this dynamic configuration manner may be ignored.

Abstract: The present application provides a method and a device for clearing a MAC forwarding entry. The method includes: detecting, by a first RB, that a topology of a network accessed by a local terminal changes; and sending, by the first RB, a first packet to a second RB, so that the second RB clears a corresponding forwarding entry after receiving the first packet, where the second RB refers to an RB configured with at least one VLAN the same as that of the first RB.

Abstract: The present invention discloses a forward entry generating method, a forward node, and a controller. The method includes: receiving, by a first forward node, MPLS forwarding path information, which is sent by a controller, of a MPLS forwarding path, where the MPLS forwarding path information includes: ingress node information, transit node information, and egress node information; sending the MPLS forwarding path information to a third forward node; and generating an MPLS forward entry of the first forward node according to the MPLS forwarding path information. According to the method, the forward node, and the controller in embodiments of the present invention, it can be avoided that the controller sends, in a point-to-point manner, MPLS forward entries to all forward nodes that an MPLS forwarding path passes through, thereby effectively improving efficiency of generating an MPLS forward entry and reducing occupation of outbound bandwidth of the controller.
Abstract translation: 本发明公开了一种前向条目生成方法，前向节点和控制器。 该方法包括：由第一转发节点接收由MPLS控制器发送的MPLS转发路径的MPLS转发路径信息，MPLS转发路径信息包括：入节点信息，传输节点信息和出口节点信息 ; 向第三个前向节点发送MPLS转发路径信息; 以及根据所述MPLS转发路径信息生成所述第一前向节点的MPLS转发表项。 根据该方法，在本发明实施例中的前向节点和控制器中，可以避免控制器将点到点的MPLS转发表项发送到MPLS转发路径经过的所有转发节点 从而有效提高了生成MPLS转发表项的效率，减少了控制器出站带宽的占用。
