摘要

【目的】

软件定义网络（SDN）设备规模日益增大，承载的业务越来越多。针对传统光传送网（OTN）设备使用简单网络管理协议（SNMP）采集性能数据不能解决大规模和高性能网络管理的问题，文章提出了基于Telemetry架构的OTN设备性能采集系统。

【方法】

通过设计分布式数据模型转换和数据编码架构，提高数据转换和编码效率以及采集系统的规模，同时均衡设备算力，设备以秒级周期定时采集并上报性能数据到采集器。

【结果】

文章对使用SNMP和部署Telemetry系统设备的性能采集能力进行了实验对比分析。

【结论】

结果表明，系统在数据模型转换和编码、数据传输效率、采集数据的时效性以及数据获取的灵活性方面更有优势，满足SDN对智能运维的要求。

Abstract

【Objective】

The scale of Software Defined Network (SDN) equipment is increasing

and more services are carried. Aiming at the problem that the traditional Optical Transport Network (OTN) devices cannot meet the requirements of large-scale and high-performance network management by using Simple Network Manager Protocol (SNMP) to collect performance data

this paper proposes an OTN device performance acquisition system based on Telemetry architecture.

【Methods】

By designing a distributed data model conversion and data coding architecture

the efficiency of data conversion and coding and the scale of the acquisition system are improved. At the same time

the computing power of the equipment is balanced. The equipment regularly collects and reports performance data to the collector in seconds.

【Results】

This paper compares and analyzes the performance collection capability of the device using SNMP and the device deploying Telemetry.

【Conclusion】

The results show that the system has more advantages in data model conversion and coding

data transmission efficiency

timeliness of data acquisition and flexibility of data acquisition

which may meet the requirements of SDN for intelligent operation and maintenance.
