Abstract: According to one embodiment of the present invention a method of operating a data network loop having at least two nodes includes monitoring deletions in an adaptive elasticity first-in, first-out (FIFO) buffer in each node, identifying each adaptive elasticity FIFO buffer that is a deleter, the deleter being an adaptive elasticity FIFO buffer for which information is deleted more often than information is inserted, and reducing a deletion threshold for each adaptive elasticity FIFO buffer that is a deleter. According to another embodiment of the present invention a buffer includes an adaptive elasticity FIFO buffer and a control circuit operatively configured to monitor deletions in the adaptive elasticity FIFO buffer, determine if the adaptive elasticity FIFO buffer is a deleter, and reduce a deletion threshold for the adaptive elasticity FIFO buffer if the adaptive elasticity FIFO buffer is a deleter.
