Abstract
Examples describe an egress port manager that uses an adaptive jitter selector to apply a jitter threshold level for a buffer, wherein the jitter threshold level is to indicate when egress of a packet segment from the buffer is allowed, wherein a packet segment comprises a packet header and wherein the jitter threshold level is adaptive based on a switch fabric load. In some examples, the jitter threshold level is to indicate a number of segments for the buffer's head of line (HOL) packet that are to be in the buffer or indicate a timer that starts at a time of issuance of a first read request for a first segment of the packet in the buffer. In some examples, the jitter threshold level is not more than a maximum transmission unit (MTU) size associated with the buffer. In some examples, a fetch scheduler is used to adapt an amount of interface overspeed to reduce packet fetching latency while attempting to prevent fabric saturation based on a switch fabric load level, wherein the fetch scheduler is to control the jitter threshold level for the buffer by forcing a jitter threshold level based on switch fabric load level and latency profile of the switch fabric.
