  1. All in-profile packets in round-robin, then all out-of-profile packets in biased round-robin.
  2. In-profile EF packets, then in-profile H2 packets, then in-profile AF packets, then out-of-profile EF packets, then out-of-profile H2 and AF packets, and then out-of-profile BE packets.
  3. In-profile EF, H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
  4. In-profile EF packets, then in-profile H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
  5. In-profile EF and H2 packets, then in-profile AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
