Abstract: The embodiments of the present invention relate to the field of computer networks, and disclose a method and an apparatus for processing a multicast packet. The method includes receiving a multicast packet, acquiring a local router interface corresponding to the multicast packet according to a multicast routing entry carried in the multicast packet, and forwarding the multicast packet through the acquired local router interface to a clustered routing system interface for further transfer. The embodiments of the present invention can cluster several routing devices into a virtual routing system which externally acts as a single routing node for supporting a multicast service, so as to implement the efficient and reliable forwarding of the multicast packet in a clustered routing system with virtual aggregation, and enable the clustered routing system to support the multicast service with high efficiency and quality.

Abstract: Disclosed is a method and a device for protecting service reliability, and the service reliability in the network virtualization system provided by the present disclosure may be ensured. In an embodiment of the present disclosure, a master node having a control function obtains the current service type information and notifies a slave node of the current service type information, for enabling the slave node to determine a main virtual link and a backup virtual link according to the service type information and to perform the failure detection, and when detecting that the main virtual link has failure and the backup virtual link has no failure, a service data message is switched to be transmitted on the backup virtual link, to ensure non-interrupted transmission of a service data message in a brand-new system architecture provided by the present disclosure, so as to ensure the service reliability.

Abstract: A method resolves connectivity of services inside a network virtualization system when a virtual cluster system supports unicast IP, L2VPN, and L3VPN services, so that the software network virtualization system can support various types of services efficiently and with high quality. The method includes: creating, on a control device, a virtualized remote logical interface for an external interface of a remote access node; identifying, by the control device according to a service configured on the virtualized remote logical interface, a service type of the service, and generating virtual link forwarding entries of the remote access node and a core aggregation node; and sending, by the control device, the virtual link forwarding entry to the remote access node and the core aggregation node, so as to set up a virtual link between the core aggregation node and the remote access node.

Abstract: The present invention relates to a method for generating a tunnel forwarding entry and a network device. An active master node in a virtual cluster network element VNE generates, according to a preconfigured tunnel service, tunnel service information with the VNE being a single network element; the active master node determines multiple nodes through which a tunnel that corresponds to the tunnel service information passes in the VNE, and node statuses of the multiple nodes through which the tunnel passes in the VNE; and local tunnel forwarding entries are generated, according to the tunnel service information and the node statuses of the multiple nodes through which the tunnel passes in the VNE, for the multiple nodes through which the tunnel passes in the VNE.
