Abstract: Examples described herein relate to a network interface device that is to adjust a transmission rate of packets based on a number of flows contributing to congestion and/or based on whether latency is increasing or decreasing. In some examples, adjusting the transmission rate of packets based on a number of flows contributing to congestion comprises adjust an additive increase (AI) parameter based on the number of flows contributing to congestion. In some examples, latency is based on a measured roundtrip time and a baseline roundtrip time.

Abstract: Examples described herein relate to a network interface and at least one processor that is to indicate whether data is associated with a machine learning operation or non-machine learning operation to manage traversal of the data through one or more network elements to a destination network element and cause the network interface to include an indication in a packet of whether the packet includes machine learning data or non-machine learning data. In some examples, the indication in a packet of whether the packet includes machine learning data or non-machine learning data comprises a priority level and wherein one or more higher priority levels identify machine learning data. In some examples, for machine learning data, the priority level is based on whether the data is associated with inference, training, or re-training operations. In some examples, for machine learning data, the priority level is based on whether the data is associated with real-time or time insensitive inference operations.

Abstract: Examples described herein relate to a switch, when operational, that is configured to receive in a packet an indicator of number of remaining bytes in a flow and to selectively send a congestion message based on a fullness level of a buffer and indication of remainder of the flow. In some examples, the indicator is received in an Internet Protocol version 4 consistent Options header field or Internet Protocol version 6 consistent Flow label field. In some examples, the congestion message comprises one or more of: an Explicit Congestion Control Notification (ECN), priority-based flow control (PFC), and/or in-band telemetry (INT). In some examples, to selectively send a congestion message to a transmitter based on a fullness level of a buffer that stored the packet and the number of remaining bytes in flow, the switch is to determine whether the buffer is large enough to store the remaining bytes in the flow.

Abstract: Examples described herein relate to a sender network interface device transmitting one or more packet probes to a receiver device, when a link is underutilized, to request information concerning link or path utilization. Based on responses to the packet probes, the sender network interface device can determine a packet transmit rate of packets of one or more flows and adjust the packet transmit rate of packets of one or more flows to increase utilization of the link.

Abstract: Examples described herein relate to a network interface device comprising: a host interface, a direct memory access (DMA) engine, and circuitry to allocate a region in a cache to store a context of a connection. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on connection reliability and wherein connection reliability comprises use of a reliable transport protocol or non-use of a reliable transport protocol. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on expected length of runtime of the connection and the expected length of runtime of the connection is based on a historic average amount of time the context for the connection was stored in the cache. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on content transmitted and the content transmitted comprises congestion messaging payload or acknowledgement. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on application-specified priority level and the application-specified priority level comprises an application-specified traffic class level or class of service level.

Abstract: A switch or network interface can detect congestion caused by a flow of packets. The switch or network interface can generate a congestion hint packet and send the congestion hint packet directly to a source transmitter of the flow of packets that caused the congestion. The congestion hint packet can include information that the source transmitter can use to determine a remedial action to attempt to alleviate or stop congestion at the switch or network interface. For example, the transmitter can reduce a transmit rate of the flow of packets and/or select another route for the flow of packets. Some or all switches or network interfaces between the source transmitter and a destination endpoint can employ flow differentiation whereby a queue is selected to accommodate for a flow's sensitivity to latency.
