RdkGponManager

Introduction

RDK GPON Manager is a component that interfaces directly with the RDK Bus.

It is   responsible for:

• Supporting GPON interfaces,
• Storing configuration and statistical data for the ONU,
• Configuring the ONU
• Polling the status of the ONU
• And communicating with other RDK Managers to prepare a GPON interface for use for WAN.

Architecture

The following diagram shows how RDK GPON Manager sits in the RDK-B architecture as well as its internal processes:

RDKGPONManager-ModuleDiagram

The RDK GPON Manager component will hold the GPON data model and will run the GPON InterfaceState Machine process.

The GPON Interface State Machine will be used to configure GPON links for WAN. By default, there will initially be 0 instances of the GPON Interface State Machine running on startup, and a new instance will be started for every ONU VEIP interface that is enabled for use.

An Event Listener Thread will be started after initialisation to receive status updates from the ONU.

System Integration

This section describes how RDK GPON Manager integrates with RDK WAN Manager and the rest of the RDK-B system.

GPON Connected

The following diagram shows how RDK GPON Manager will handle setting up a   connected GPON interface. Every box represents a state that the corresponding Manager or Module is   in, while every arrow represents either a transition between states, or event messages between Managers and Modules.

Process-SettingUpGPON

Since the OLT controls the PLOAM and OMCI configuration, the ONU will be expected to configure the GPON connection outside of RDK GPON Manager’s control.

RDK GPON Manager will simply monitor the ONU’s Registration State as well as the status of the VEIP interface, which is the interface presented to the Gateway. Once the VEIP interface is ready for use, RDK GPON Manager will communicate with RDK Ethernet Manager to configure that VEIP interface for WAN, in a similar way to how a physical Ethernet interface would be used for WANoE. This allows the WAN control mechanism to be generic across all Ethernet interfaces, physical or virtual, and simplifies RDK GPONManager.
