Abstract
System, method and apparatus for network congestion management and network resource isolation. A high level network usage and device architecture is provided that can satisfy buffering and network bandwidth resource management for data center networks. The congestion management can be defined to bring the reaction point closer to the network ports. In one embodiment, the reaction point is resident in a network interface card (NIC).
Claims20
A method, comprising:
- receiving a message at a network interface card, the message including information that enables identification of a congestion condition;
- and
- modifying a state of a scheduler and shaper module in the network interface card based on the received message, wherein the state of the scheduler and shaper module is used to determine a selection of packets for transmission from a plurality of transmit queues associated with one or more flows.
A method, comprising:
- receiving traffic at a network interface card;
- metering the received traffic using a scheduler and shaper module in the network interface card based, wherein the scheduler and shaper module is used to control the delivery of packets to a plurality of receive queues associated with one or more flows;
- and
- transmitting, by the network interface card based on the metering, a message that includes information that enables identification of a congestion condition to an upstream location.
1 more element
A network interface card, comprising:
- a receiver that is configured to receive a message at the network interface card, the message including information that enables identification of a congestion condition;
- and
- a transmit packet processing unit that is configured to modify a state of a scheduler and shaper module in the network interface card based on the received message, wherein the state of the scheduler and shaper module is used to determine a selection of packets for transmission from a plurality of transmit queues associated with one or more flows.
