Abstract
Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.
Claims20
A packet control method, comprising:
- detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node;
- reducing, by the network node, a scheduling priority of the packet in the packet flow;
- generating, by the network node, a congestion isolation message, wherein the congestion isolation message comprises description information of the packet flow;
- and
- sending, by the network node, the congestion isolation message to the upstream node, the congestion isolation message instructing the upstream node to reduce the scheduling priority of the packet in the packet flow.
A packet control device, comprising:
- one or more processors;
- and
- one or more memories coupled to the one or more processor and storing programming instructions for execution by the one or more processors to perform operations comprising:
- detecting a packet in a packet flow causing a congestion from an upstream node;
- reducing a scheduling priority of the packet in the packet flow;
- generating a congestion isolation message, wherein the congestion isolation message comprises description information of the packet flow;
- sending the congestion isolation message to the upstream node, the congestion isolation message instructing the upstream node to reduce the scheduling priority of the packet in the packet flow.
A system, comprising:
- a packet control device;
- an upstream node;
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to instruct the packet control device to:
- detect a packet in a packet flow causing a congestion from an upstream node;
- reduce a scheduling priority of the packet in the packet flow;
- generate a congestion isolation message, wherein the congestion isolation message comprises description information of the packet flow;
- send the congestion isolation message to the upstream node, the congestion isolation message instructing the upstream node to reduce the scheduling priority of the packet in the packet flow;
- and
- wherein the one or more memories store the programming instructions for execution by the at least one processor to instruct the upstream node to:
- receive the congestion isolation message;
- and
- reduce the scheduling priority of the packet in the packet flow indicated by the description information.
