Method and system for dynamically virtualizing performance management function of entity OLT

Abstract

The invention discloses a method and a system for dynamically virtualizing a performance management function of an entity OLT (Optical Line Terminal), and relates to the field of network function virtualization of embedded access equipment, the method comprises the following steps: creating and associating a corresponding virtual OLT application instance for each entity OLT on a virtualization platform; a virtual OLT application example judges whether the virtual OLT application example carries out local processing or forwards the request message to a corresponding entity OLT for processing according to the request message sent by the webmaster; and the entity OLT judges whether the own computing resource utilization rate exceeds a preset upper limit or is lower than a preset lower limit,and transfers the main body of the processing performance management function between the entity OLT and the virtual OLT application instance when the computing resource exceeds the preset upper limitor is lower than the preset lower limit. The performance management function of the entity OLT can be dynamically migrated between the entity OLT and the virtualization platform, so that the purposesof flexible function expansion and optimal resource allocation and saving are achieved.

Description

technical field [0001] The invention relates to the field of network function virtualization of embedded access devices, in particular to a method and system for dynamic virtualization of performance management functions of an entity OLT. Background technique [0002] The performance management function of the existing physical OLT (optical line terminal, optical line terminal) is usually collected by the physical OLT master control, each board card, and the ONU (Optical Network Unit, optical network unit) attached to each board card, etc. All performance parameters of the management objects are stored in the memory of the main control, so that the third-party network management system can respond in time when collecting performance data. [0003] However, the range of management objects and the collection cycle of the third-party network management system performance data collection are unpredictable, so the physical OLT needs to save the complete set of performance paramet...

AI Technical Summary

Problems solved by technology

When the memory resources of the physical OLT are insufficient, some performance data will be lost, and when the third-party network management system frequently collects a large amount of performance data, it will occupy a large amount of CPU computing power of the physical OLT for a long time, resulting in the inability to process other data of the physical OLT in a timely manner. important computing tasks
