Embodiment Construction

[0063] It should be understood at the outset that, although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0064] Operations, administration, and management (OAM), or operations, administration, and maintenance (OAM), refers to the process of operating, supervising, managing, and maintaining any system The processes, activities, tools, and standards involved are typically applied to telecommunications, computer networks, and computer hardware.

[0065] Unlike unicast traffic, existing multicast traffic ...

Abstract

Disclosed is a hop-by-hop postcard technology. The implementation of the Post Card (Post Card) technology improves a Post Card-based Telemetry (Post Card-based Telemetry, PBT), and the implementation of the Post Card (Post Card) technology can be used to improve the Post Card-based Telemetry (PBT). A segment-by-segment postcard technique is also disclosed. Implementing the segment-by-segment postcard technique improves in-band OAM (In-site OAM, IOAM). Appropriate intra-path telemetry for multicast traffic may be achieved by these techniques. In addition, the techniques may be used to reconstruct and visualize multicast trees for performance monitoring and fault handling.

Description

technical field [0001] The present invention relates generally to multicast traffic, and more particularly to in-path telemetry of multicast traffic. Background technique [0002] Multicast traffic is an important traffic type in today's Internet. Services provided by multicast are usually real-time services (such as online conferences) or have strict quality of service (quality of service, QoS) requirements (such as IP television (Internet Protocol television, IPTV)). Therefore, discarding or delaying multicast packets will seriously affect application performance and user experience. Therefore, the performance of multicast traffic is usually closely monitored. Contents of the invention [0003] A first aspect relates to a method for nodes in a multicast network to collect in-path telemetry data. The method includes collecting the in-path telemetry data according to an instruction header, wherein the instruction header identifies in-path telemetry data to be collected ...
