US 12,764,592 B2 · System for low latency, low loss, and scalable throughput (L4S) traffic mapping

Abstract

Devices, networks, systems, methods, and processes for detecting and mapping Low Latency, Low Loss, and Scalable throughput (LAS) traffic are described herein. A device may determine that a data flow is LAS. The device can determine an initial Quality of Service (QoS) value associated with the data flow. The device may determine one or more network policies associated with one or more QoS levels. The device can determine a QoS ceiling value associated with a highest QoS level of the one or more QoS levels. The device may mark the data flow with the QoS ceiling value if the initial QoS value is lower than the QoS ceiling value, thereby mapping the data flow to the highest QoS level. The device can also maintain the initial QoS value if the initial QoS value is greater than the QoS ceiling value, as an exception to the one or more network policies.

Dependent claims

A device, comprising:

a processor;
a memory communicatively coupled to the processor;
and
a traffic mapping logic, configured to:
receive a data flow including at least one data packet;
determine that the data flow is a Low Latency, Low Loss, Scalable throughput (L4S) data flow;
identify an initial Quality of Service (QoS) value in at least one initial header of the at least one data packet;
determine one or more network policies associated with the LAS data flow;
map one of the at least one data packet based on the initial QoS value and the one or more network policies;
determine a DSCP ceiling value associated with a highest QoS level;
and
assign the DSCP ceiling value to the data flow.
