1. A method for carrying more than one type of traffic on a single physical link, the method comprising:

  • logically partitioning traffic on a physical link of a network device into a plurality of virtual lanes;

    receiving first traffic into the physical link of the network device;

    determining whether the first traffic indicates a first virtual lane based on the first traffic indicating a protocol that recovers from dropping of the first traffic or indicates a second virtual lane based on the first traffic indicating a protocol that does not recover from dropping of the first traffic; and

    applying a first set of rules or a second set of rules to the first traffic based on whether it is determined that the first traffic indicates the first lane or the second lane, wherein the first set of rules applies a probabilistic drop function to the first traffic in response to latency and the second set of rules does not cause frames from the second traffic to be dropped in response to latency.
