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] Such as 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, and a VOMCI access instance, a VOMCI function instance, and an ONU status and command database are deployed in the cloud platform.

[0040] Among them, the OLT is used to send the ONU management request to the VOMCI access instance, and the VOMCI access instance processes it according to the type of 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 a small amount of status update, if it is an ONU service management request, then 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 previously processed this ONU, And the VOMCI function instan...

Embodiment 2

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

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

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

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

Embodiment 3

[0051] In the OMCI function virtualization system of the OLT device that the embodiment of the present invention provides, the function of the VOMCI function example is as follows:

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

Abstract

The invention discloses an OMCI function virtualization system of OLT equipment. A VOMCI access instance, a VOMCI function instance and an ONU state and command database are deployed in the cloud platform. The OLT sends the ONU management request to the VOMCI access instance; the VOMCI access instance is processed according to the type of the ONU management request; if the request is an ONU objectupdating request, the ONU state and command database are directly updated, and if the request is an ONU service management request, a proper VOMCI function instance is selected and the ONU service management request is forwarded to the VOMCI function instance for processing; when the VOMCI function instance processes an ONU service management request, whether the latest state data of the ONU is in a local memory or not is checked; and if the latest state data of the ONU is not in the local memory, the latest state data of the ONU is searched and downloaded from the ONU state and command database, and the latest state data of the ONU is synchronized to the ONU state and command database by the VOMCI function instance in the process of processing the ONU service management request. According to the invention, the high availability, load balance and continuous processing capability of an OLT virtualization system can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically relates to an OMCI function virtualization system of an OLT device. Background technique [0002] Generally, network communication equipment is composed of dedicated hardware and software. NFV (Network Functions Virtualization, Network Function Virtualization) generally separates some software functions originally running on dedicated hardware from the software running on dedicated hardware and puts them in a separate It runs on standard commercial servers, so as to reduce the cost of equipment and speed up the speed of products and services to the market. The OMCI (ONU Management and Control Interface, optical network unit management control interface) protocol of the OLT (Optical Line Terminal, optical line terminal) is a GPON (Gigabit-Capable Passive Optical Networks, gigabit passive optical network technology) OLT and GPONONU ( The management protocol between Opti...
