MICRO SEGMENT IDENTIFIER INSTRUCTIONS FOR PATH TRACING OPTIMIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18234276 titled 'MICRO SEGMENT IDENTIFIER INSTRUCTIONS FOR PATH TRACING OPTIMIZATION
Simplified Explanation
- The patent application describes techniques for optimizing network path tracing and network delay measurements. - One technique involves using an IPv header option or segment identifier field as a carrier for telemetry data. - Another technique involves using an SRv6 micro-segment instruction to instruct a network node to perform path tracing actions. - Short interface identifiers can be used to trace the path of a packet through a network. - Short timestamps can be used to measure delays associated with sending a packet through a network. - These techniques can be used together to optimize network path tracing and delay measurement techniques.
Original Abstract Submitted
Techniques for optimizing technologies related to network path tracing and network delay measurements are described herein. Some of the techniques may include using an IPv header option and/or segment identifier field of a segment list or a TLV of a segment routing header as a telemetry data carrier. The techniques may also include using an SRv6 micro-segment (uSID) instruction to indicate to a node of a network that the node is to perform one or more path tracing actions and encapsulating the packet and forward. Additionally, the techniques may include using short interface identifiers corresponding to node interfaces to trace a packet path through a network. Further, the techniques may include using short timestamps to determine delay measurements associated with sending a packet through a network. In various examples, the techniques described above and herein may be used with each other to optimize network path tracing and delay measurement techniques.
