PACKET SENDING METHOD, NETWORK NODE, AND SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324670 titled 'PACKET SENDING METHOD, NETWORK NODE, AND SYSTEM

Simplified Explanation

The patent application describes a controller that determines a forwarding path for a service flow based on its latency requirement.

  • The controller identifies the nodes that forward the packet and determines the corresponding adjacent segment identifiers.
  • The controller generates a label stack that includes the adjacent segment identifiers.
  • The label stack is sent to the ingress node to instruct it to forward the packet within a specific time period.
  • The controller determines the forwarding path based on the latency requirement and generates a label stack corresponding to a forwarding time point.


Original Abstract Submitted

A controller obtains a forwarding latency requirement of a service flow and a destination address of the service flow, and determines a forwarding path that meets the forwarding latency requirement. The controller determines that an ingress node forwards a first cycle time number of a packet and an intermediate node forwards a second cycle time number of the packet, and separately determines a corresponding adjacent segment identifier. A label stack generated by the controller includes the adjacent segment identifier and the adjacent segment identifier. The controller sends the label stack to the ingress node, to trigger the ingress node to forward the packet within a period of time corresponding to the first cycle time number. The controller determines the forwarding path based on the forwarding latency requirement of the service flow, and generates a label stack corresponding to a forwarding time point.
