Problems solved by technology

However, the existing segment routing network can only implement simple OAM functions such as LSP ping and tracert (trace routing), but cannot implement complex OAM functions such as in-band OAM path verification and end-to-end logical path reachability detection.
[0005] However, in the existing technical solutions and IOAM technology, it is impossible to realize the capability notification of IOAM nodes

Abstract

The invention relates to a method for realizing IOAM. The method comprises the steps of: extending the IOAM capability information of routing protocol carrying equipment; and encapsulating the IOAM capability information in a routing protocol message, and sending in a network. The invention relates to a device for realizing IOAM. In the scheme, an IOAM node can notify the IOAM capability and the IOAM attribute information itself in the network; the robustness of the network is improved; and the operation, maintenance and management capability of the network is improved.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, network communication technologies, and in particular, relate to a method and device for realizing in-band operation management and maintenance IOAM. Background technique [0002] IOAM (in-suit OAM, also known as in-band OAM (Operations, Administration, and Maintenance), in-band operation management and maintenance), in-band operation management and maintenance refers to directly encapsulating the OAM information and data that needs to be carried in the user datagram In this paper, the OAM data is sent together with the user message, and no additional control plane message is required to send the OAM data. IOAM can realize complex OAM functions such as multiple network fault detection functions, packet path consistency detection, POT (intermediate transmission node verification), SLA (Service-Level Agreement, Service Level Agreement) verification. [0003] At the edge node of the ...
