Network node for supporting performance evaluation using performance bitmap

Abstract

The present invention relates to the field of computer networks and to performance evaluation in such networks. The performance measurement is performed by a network node using a status field with a performance bitmap. The present invention thus provides a network node for supporting performance evaluation, wherein the network node is configured to obtain a packet comprising a status field, wherein the status field includes a hop count value and a performance bitmap; update a bit in the performance bitmap based on performance information obtained in the network node and based on the hop count value; increment the hop count value; and forward the updated packet.

Description

technical field [0001] The present invention relates to computer network technology and performance evaluation in such networks. Said performance measurement is performed by a network node via a status field with a performance bitmap. Background technique [0002] Performance measurement and fault detection are key capabilities of communication networks. Furthermore, they are also key capabilities for autonomous networks, an area that has grown rapidly over the past few years. Measurement data is usually collected by a central management server. The central management server analyzes the data and makes intelligent decisions (possibly based on artificial intelligence) that affect the network, including, for example, determining network paths, allocating network resources, and determining network security policies. [0003] In-band network telemetry (INT) and insitu operations, administration and maintenance (IOAM) are two examples of network performance measurement methods...
