Aspects disclosed in the detailed description include head-of-line blocking (HOLB) mitigation in communication devices. Output queues employed by a communication device for transmitting data are susceptible to HOLB. In this regard, in one aspect, a queue monitoring logic is configured to detect HOLB by measuring and comparing a depth(s) of an output queue(s) against a queue-overflow threshold. If the depth(s) of the output queue(s) exceeds the queue-overflow threshold, a queue weight(s) of a corresponding input queue(s) is decreased to reduce data flow into the output queue(s), thus mitigating the HOLB in the output queue(s). In another aspect, the queue monitoring logic is configured to detect queue depletion by comparing the depth(s) of the output queue(s) against a queue-depletion threshold. By mitigating the HOLB and the data starvation in the output queue(s), it is possible to optimize the output queue(s) to achieve higher throughput and data integrity with lower power consumption. |
