Method and system for multi-domain-based low latency, low loss, and scalable throughput congestion control

One or more network devices comprising:

• one or more processors, wherein the one or more processors are configured to:
• receive first state information from low latency, low loss, scalable throughput (L4S) capable devices associated with domains that support a packet flow end-to-end via a network;
• analyze the first state information;
• determine, in response to the analysis, congestion pertaining to the packet flow;
• select a first L4S capable device of a first domain of the L4S capable devices and the domains based on a predetermined order of the domains for which congestion control responses are to be provided, wherein the predetermined order is configured prior to receiving the first state information;
• generate a first congestion control response;
• and
• transmit to the first L4S capable device, the first congestion control response.

A non-transitory computer-readable storage medium storing instructions executable by one or more processors of one or more network devices, wherein the instructions are configured to:

• receive first state information from low latency, low loss, scalable throughput (L4S) capable devices associated with domains that support a packet flow end-to-end via a network;
• analyze the first state information;
• determine, in response to the analysis, congestion pertaining to the packet flow;
• select a first L4S capable device of a first domain of the L4S capable devices and the domains based on a predetermined order of the domains for which congestion control responses are to be provided, wherein the predetermined order is configured prior to receiving the first state information;
• generate a first congestion control response;
• and
• transmit to the first L4S capable device, the first congestion control response.
