Abstract
The present application discloses data processing methods. Example methods include obtaining information about a header field of a data packet and searching an exact match flow table for an exact match entry that matches the data packet. When the matching exact match is found, a determination is made as to whether an update time of a wildcard entry corresponding to the exact match entry is before a creation time of the exact match entry. In response to determining that the update time is before the creation time of the exact match entry, the data packet is processed according to an action instruction corresponding to the exact match entry. In response to determining that the update time of the wildcard entry corresponding to the exact match entry is not before the creation time of the exact match entry, the exact match entry is deleted.
