Abstract: Examples described herein can be used to allocate replacement receive buffers for use by a network interface, switch, or accelerator. Multiple refill queues can be used to receive identifications of available receive buffers. A refill processor can select one or more identifications from a refill queue and allocate the identifications to a buffer queue. None of the refill queues is locked from receiving identifications of available receive buffers but merely one of the refill buffers is accessed at a time to provide identifications of available receive buffers. Identifications of available receive buffers from the buffer queue are provide to the network interface, switch, or accelerator to store content of received packets.

The transmission and reception of data frames over the different primary channels are synchronized to prevent or mitigate inter-channel interference. According to some embodiments, the channels are synchronized using back-off procedures and/or padding to align the ending time of transmitted and received data frames, for example.
