Abstract
A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a coordinated domain-based low latency, low loss, and scalable throughput (L4S) service. The service may provide independent feedback loops of state information from each domain and associated L4S device. The feedback loops may operate on different timescales. The service may coordinate congestion control across domains of an end-to-end path that support a packet flow and prevent fragmented or contentious congestion control responses between the domains.
Claims20
A method comprising:
- receiving first state information from low latency, low loss, scalable throughput (L4S) capable devices associated with different domains that support a packet flow end-to-end via a network;
- analyzing the first state information;
- determining congestion pertaining to the packet flow;
- selecting a first L4S capable device of the L4S capable devices that resides in a first domain of the domains;
- generating a first congestion control response;
- and
- transmitting the first congestion control response to the first L4S capable device.
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 different domains that support a packet flow end-to-end via a network;
- analyze the first state information;
- determine congestion pertaining to the packet flow;
- select a first L4S capable device of the L4S capable devices that resides in a first domain of the domains;
- generate a first congestion control response;
- and
- transmit the first congestion control response to the first L4S capable device.
A non-transitory computer-readable storage medium storing instructions executable by one or more processors of one or more network devices that configure the one or more network devices to:
- receive first state information from low latency, low loss, scalable throughput (L4S) capable devices associated with different domains that support a packet flow end-to-end via a network;
- analyze the first state information;
- determine congestion pertaining to the packet flow;
- select a first L4S capable device of the L4S capable devices that resides in a first domain of the domains;
- generate a first congestion control response;
- and
- transmit the first congestion control response to the first L4S capable device.
