Problems solved by technology

If an idle VOMCI function instance is added, it cannot replace the VOMCI function instance to manage the related ONU, and it cannot continue to process the pending ONU service management request command that has not been processed in the previous VOMCI function instance, so it cannot Support high availability and load balancing of the entire system

Embodiment 1

[0039] like figure 1 As shown, the OMCI function virtualization system of the OLT device provided by the embodiment of the present invention consists of an OLT, an ONU, and a cloud platform. The cloud platform deploys a VOMCI access instance, a VOMCI function instance, and an ONU status and command database.

[0040] The OLT is used to send the ONU management request to the VOMCI access instance. The VOMCI access instance processes the ONU management request according to the type of the ONU management request. If it is an ONU object update request, it directly updates the ONU status and command database to create the ONU object. , delete and update a small amount of status, if it is an ONU service management request, select a suitable VOMCI function instance and forward the ONU service management request to the VOMCI function instance for processing (for example, if there is a VOMCI function instance that has processed this ONU before, And the VOMCI function instance is availa...

Embodiment 2

[0042] In the OMCI function virtualization system of the OLT device provided by the embodiment of the present invention, the function of the VOMCI access instance is as follows:

[0043] (1) Process or forward all outgoing ONU management requests from the OLT. Each ONU management request outgoing from the OLT is only sent to the VOMCI access instance, and the VOMCI access instance directly processes or forwards it to the VOMCI access instance according to the type of ONU management request. A VOMCI function instance is processed, and the processing result of the VOMCI function instance is sent back to the OLT that issued the ONU management request.

[0044] (2) Maintain the working status of all VOMCI function instances.

[0045] When the VOMCI function instance is started, it registers with the VOMCI access instance. And periodically report its own capability information (currently processed ONU number, CPU, memory resource utilization, etc.). On the other hand, the VOMCI a...

Embodiment 3

[0051] In the OMCI function virtualization system of the OLT device provided by the embodiment of the present invention, the function of the VOMCI function instance is as follows:

[0052] After the VOMCI function instance receives the ONU service management request from the VOMCI access instance, it checks whether the execution environment for the ONU service management request is available. If so, the ONU service management request is translated into one or more OMCI command sequences, and the ONU service The OLT carried in the management request carries the transmission channel specified by the OMCI message channel parameter, and completes the OMCI message interaction with the ONU (transited by the OLT). And generate an ONU service management response reply to the VOMCI access instance.

Abstract

The invention discloses an OMCI function virtualization system of an OLT device. A VOMCI access instance, a VOMCI function instance, and an ONU status and command database are deployed on a cloud platform. The OLT sends an ONU management request to the VOMCI access instance, and the VOMCI access instance Process according to the type of ONU management request, if it is an ONU object update request, directly update the ONU status and command database, if it is an ONU service management request, select a suitable VOMCI function instance and forward the ONU service management request to the VOMCI function Instance processing; when a VOMCI function instance processes an ONU service management request, check whether the latest status data of the ONU is in the local memory, if not, search and download the latest status data of the ONU from the ONU status and command database, and process the ONU business During the management request process, the VOMCI function instance synchronizes the latest status data of the ONU to the ONU status and command database. The invention can significantly improve the high availability, load balancing and connection processing capabilities of the OLT virtualized system.

Description

technical field [0001] The invention belongs to the technical field of communication, and more particularly, relates to an OMCI function virtualization system of an OLT device. Background technique [0002] Usually network communication equipment consists of dedicated hardware and software. NFV (Network Functions Virtualization) generally separates some software functions originally running on dedicated hardware from the software running in dedicated hardware and puts them in a separate It runs on standard commodity servers, thereby reducing the cost of equipment and accelerating the speed of bringing products and services to market. The OMCI (ONU Management and Control Interface, Optical Network Unit Management Control Interface) protocol of OLT (Optical Line Terminal, Optical Line Terminal) is GPON (Gigabit-Capable Passive Optical Networks, Gigabit Passive Optical Network Technology) OLT and GPONONU ( The management protocol between the Optical Network Unit, usually runs ...
