Abstract: An OAM packet processing method includes generating, by a first network device, an OAM packet, where the OAM packet is an MPLS-TP packet that includes an identifier of the first network device and indication information indicating a type of the identifier of the first network device. The first network device sends the OAM packet to the second network device. After receiving the OAM packet, the second network device can determine, based on the indication information, the type of the identifier of the first network device that is carried in the OAM packet, and accurately read the identifier of the first network device from the OAM packet. Therefore, MPLS-TP OAM can be implemented in a plurality of scenarios such as an IPv4 network, an IPv6 network, and a network including IPv4 and IPv6, to expand an application scope of MPLS-TP OAM.

Abstract: The present disclosure provides a decoding method and apparatus. The decoding method mainly includes: extracting pre-indexed information, storing the pre-indexed information in another file associated with a to-be-decoded file or a tail end of the to-be-decoded file, then reading the pre-indexed information before decoding is performed, and performing parallel decoding on multiple data segments in the to-be-decoded file according to the pre-indexed information. Using the foregoing storage method for the pre-indexed information may effectively reduce an I/O operation when the pre-indexed information is read, so as to avoid, to some extent, a system frame freezing phenomenon that may be caused when decoding is performed.
