摘要： Embodiments of the present invention provide a method and a device for processing a failure in at least one distributed cluster, and a system. The at least one distributed cluster includes a first distributed cluster. The first distributed cluster includes a first Master node, a first Slave node, a first reference node, and a first secondary node that serves as a backup of the first Master node. The first secondary node receives a heartbeat message that is sent by the first reference node and that includes first indication information that is used to indicate that the first reference node is disconnected from the first Master node. The first secondary node determines, according to the first indication information, that the first reference node is disconnected from the first Master node. When it is detected that a heartbeat message sent by the first Master node to the first secondary node is interrupted, the first secondary node determines that the first secondary node is also disconnected from the first Master node. The first secondary node determines that the first Master node is faulty. In the embodiments of the present invention, a failure detection time can be effectively shortened.

摘要： Embodiments of the present invention provide a failure protection method based on a ring protection link, a device, and a system, and nodes in the ring protection link include a forwarding device in an SDN. The method includes: receiving, by a network controller, a high-priority failure message sent by a first node, where the failure message includes information used to indicate a failure, and the first node is any one node in the ring protection link; obtaining, according to the failure message, data information about port state changes that are of the nodes and that are caused by the failure; and sending a high-priority switching message to each of the nodes, so that each of the nodes updates a local MAC address table according to the switching message, to complete failure protection based on the ring protection link, where the switching message includes the data information about port state changes that are of the nodes and that are caused by the failure. In the embodiments of the present invention, failure protection is implemented in priority in a centralized manner through exchange of the high-priority failure message and the high-priority switching message between the first node and the network controller, so as to implement quick ring protection link switching upon a failure in the SDN.

摘要： Semi-automatic failover includes automatic failover by a service provider as well as self-serviced failover by a service consumer. A signal can be afforded by a service provider based on analysis of an incident that affects the service provider. Initiation of self-serviced failover by a service consumer can be predicated on the signal. In one instance, the signal provides information that aids a decision of whether or not to failover. In another instance, the signal can grant or deny permission to perform a self-serviced failover.
