Abstract
Methods, systems, and computer program products for killing prioritized packets in multiple queues using time-to-live values to prevent head-of-line blocking. In one example, a method for scheduling prioritized packets in queuing system includes receiving a plurality of packets having a plurality of different priorities. The method can also include assigning the packets to the queues, wherein at least some of the queues include packets of a plurality of different priorities. In addition, the method can include assigning a first time-to-live (TTL) value to a first packet in a first queue. The method can also include altering the first TTL value of the first packet in response to a second packet of a second queue being scheduled. Further, the method can include discarding the first packet in response to the first TTL value having a predetermined relationship with respect to a predetermined value.
