TransportPCE User Guide

Overview

TransportPCE describes an application running on top of the OpenDaylight controller. Its primary function is to control an optical transport infrastructure using a non-proprietary South Bound Interface (SBI). It may be interconnected with Controllers of different layers (L2, L3 Controller…), a higher layer Controller and/or an Orchestrator through non-proprietary Application Programing Interfaces (APIs). Control includes the capability to configure the optical equipment, and to provision services according to a request coming from a higher layer controller and/or an orchestrator. This capability may rely on the controller only or it may be delegated to distributed (standardized) protocols.

It provides basic alarm/fault and performance monitoring, but this function might be externalized to improve the scalability. A Graphical User Interface has been developped separately and is not proposed here since automated control does not imply user interactions at the transport controller level.

TransportPCE modular architecture is described on the next diagram. Each main function such as Topology management, Path Calculation Engine (PCE), Service handler, Renderer responsible for the path configuration through optical equipment and Optical Line Management (OLM) is associated with a generic block relying on open models, each of them communicating through published APIs.

TransportPCE User-Facing Features

  • odl-transportpce

    • This feature contains all other features/bundles of TransportPCE project. If you install it, it provides all functions that the TransportPCE project can support. It exposes all Transportpce project specific models defined in “Service-path”. These models complement OpenROADM models describing South and Northbound APIs, and define the data structure used to interconnect the generic blocks/functions described on the previous diagram.

  • feature odl-transportpce-tapi

    • This feature provides transportPCE a limited support of TAPI version 2.1.2 Northbound interface.

  • feature odl-transportpce-inventory

    • This feature is considered experimental. It provides transportPCE with an external connector to a MariaDB inventory currently limited to OpenROADM 1.2.1 devices.

How To Start

Preparing for Installation

  1. Devices must support the standard OpenROADM Models more precisely versions 1.2.1 and 2.2.1. Since Magnesium SR0, an OTN experimental support is provided for OpenROADM devices 2.2.1.

  2. Devices must support configuration through NETCONF protocol/API.

Installation Feature

Run OpenDaylight and install TransportPCE Service odl-transportpce as below:

feature:install odl-transportpce

if you need TAPI limited support, then run:

feature:install odl-transportpce-tapi

if you need the inventory external connector support limited to 1.2.1 OpenROADM devices, then run:

feature:install odl-transportpce-inventory
