Switch-originated congestion messages

摘要: Examples described herein relate to a switch circuitry that includes circuitry to determine if a received packet com prises a control packet; circuitry to determine congestion metrics based on receipt of at least one control packet, wherein the at least one control packet comprises a Request To Send (RTS) or Clear To Send (CTS); and circuitry to transmit at least one of the congestion metrics in at least one packet to a sender and/or receiver network interface device.
