Research on OTN Equipment Performance Collection System based on Telemetry Architecture
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.
