Abstract
An optical transmission apparatus includes an extractor that extracts information indicating port allocation to each slot of a reception signal; a comparator that based on the extracted information and for a given slot among the slots, obtains a count of the slots allocated the same port as the given slot and compares the obtained count of slots and an expected value for the given slot; and a memory that stores therein for each slot, an expected value for the count of slots allocated the same port as the slot. The comparator detects a mismatch concerning the given slot, when the obtained count of slots and the expected value for the given slot differ.
