Abstract: The disclosed apparatuses and methods are directed to data plane restoration in a network. A method comprises receiving a label-switched path (LSP) failure notification indicating a failure in a network; generating, by a node of the network, a fast-restoration (FR) message and transmitting the FR message to a second node of the message forwarding path. The FR message comprises: a plurality of forwarding instruction objects (FIOs) having forwarding instructions for the FR message for each node of a message forwarding path; and a plurality of label-switched path objects (LSPOs) having a restoration LSP data for each node of a protection detour path. Another method comprises receiving the FR message; generating a modified FR message based on the FR message; and transmitting the modified FR message to another node of the message forwarding path based on the FIO, prior to processing the FR message by the node.

Abstract: This application discloses an exception handling method, which may be applied to a processor. The method includes: The processor calls a second function according to a call instruction of a first function, where the first function is a high-level language function, and the second function is a runtime function. When an exception occurs in a process of executing the second function, the processor executes a return operation of the second function, where the return operation of the second function includes restoring a status of a first register used when the second function is executed to a status before the first function calls the second function. The processor performs exception handling based on the status of the first register. The method can improve running performance of the processor.
