摘要： A primary-backup replication capability is disclosed. A primary process and a backup process participate in a synchronization process configured to synchronize state information of the primary and backup processes. The synchronization process operates in periods of time referred to as epochs. During the current epoch, the primary process computes state update information representing changes to the state information of the primary process since a previous epoch, and also buffers output messages generated during the current epoch in an associated output buffer dedicated for use in the current epoch. The primary process initiates a new epoch independent of receiving, from the backup process, a state update acknowledgement for the previous epoch. The output messages buffered for the current epoch are released from the associated output buffer after the primary process receives a state update acknowledgment for the current epoch and all output buffers of all previous epochs are empty.

摘要： The backup-in-the-middle primary-backup configuration is created by placing a backup-in-the-middle forwarder in the routing path between the primary and the environment. The backup-in-the-middle forwarder intercepts output messages along with required state information sent by the primary to the environment. The backup-in-the-middle forwarder backs up the primary by updating its state information and forwards the output packets to the environment.

摘要： An efficient protection scheme for MPLS multicast is disclosed for protection of Point-to-Multi-Point LSP connections. The efficient protection scheme for MPLS multicast includes a pair of Redundant Multicast Trees for each multicast connection which connects the source of a multicast LSP to all its destinations in such a way that in the event of a single link or node failure in the network, every destination node is still connected to the root node in at least one of the two trees. Furthermore, a method is disclosed that ensures that existing Redundant Multicast Trees can adapt to changes in the set of destination nodes and/or network topology changes without significant modifications. The efficient protection scheme for MPLS multicast is particularly useful for reducing the protection bandwidth requirements over protection methods known in the art.
