Low latency, low loss, scalable throughput queuing and marking

A system comprising:

• a memory storage;
• and
• a processing unit coupled to the memory storage, wherein the processing unit is operative to:
• determine, in layer 2, a packet is experiencing congestion;
• send a Low Latency, Low Loss, Scalable Throughput (L4S) marking request to layer 3 to request congestion marking of the packet;
• mark the packet in layer 3 for congestion experienced;
• and
• send a L4S marking response comprising the marked packet to layer 2.

A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:

• determining, in layer 2, a packet is experiencing congestion;
• sending a Low Latency, Low Loss, Scalable Throughput (L4S) marking request to layer 3 to request congestion marking of the packet;
• marking the packet in layer 3 for congestion experienced;
• and
• sending a L4S marking response comprising the marked packet to layer 2.
