The invention concerns a method for taking into account priority levels which consists in storing in a processing queue, in their arrival sequence for retransmission in the output port, packet identifiers to be retransmitted and in carrying out, by backtracking step by step through the processing queue, a series of pairing comparisons of the identifiers present in the processing queue, using a bank of working registers (RD) and maintaining in the bank of working registers (RD) the identifier concerned at the end of each comparison as the earliest in the highest priority level, said operations being carried out in a queue memory (224) managed by means of four pointers: a read pointer (PL), a write pointer (PE), an auxiliary read pointer (PAL) and an auxiliary write pointer (PAE). |
