OpenDaylight SDN Controller - Introduction

This document provides an overview of OpenDaylight (ODL) and instructions for getting started with ODL on a Raspberry Pi 3 using Mininet and the REST interface. It includes the following sections: 1. Introduction to ODL including its architecture, community, and releases. 2. Instructions for installing Java, downloading and running ODL, and installing features using Karaf. 3. Directions for connecting Mininet to the ODL instance and using DLUX and RESTconf to view and interact with the network topology and nodes. 4. Information on the REST interface and how to use curl and Yang UI/Yangman to send requests and view responses regarding the network topology and inventory.

5 / 56 ODL OpenDaylight OpenDaylight (ODL) is a modular open platform for customizing and automating networks of any size and scale. The OpenDaylight Project arose out of the SDN movement, with a clear focus on network programmability. It was designed from the outset as a foundation for commercial solutions that address a variety of use cases in existing network environments. ODL is driven by a global, collaborative community of vendor and user organizations that continuously adapts to support the industry's broadest set of SDN and NFV use cases. With over 1000 developers, 50 member organizations and supporting approximately 1 billion subscribers around the world, OpenDaylight is quickly evolving integrated toolchains for leading use cases.

9 / 56 ODL Architecture Model-Driven The core of the OpenDaylight platform is the Model-Driven Service Abstraction Layer (MD-SAL). In OpenDaylight, underlying network devices and network applications are all represented as objects, or models, whose interactions are processed within the SAL. The SAL is a data exchange and adaptation mechanism between YANG models representing network devices and applications. The YANG models provide generalized descriptions of a device or application's capabilities without requiring either to know the speci c implementation details of the other. Within the SAL, models are simply de ned by their respective roles in a given interaction. A "producer" model implements an API and provides the API's data; a "consumer" model uses the API and consumes the API's data. While 'northbound' and 'southbound' provide a network engineer's view of the SAL, 'consumer' and 'producer' are more accurate descriptions of interactions within the SAL. For example, protocol plugin and its associated model can either be a producer of information about the underlying network, or a consumer of application instructions it receives via the SAL.
10 / 56 ODL Architecture Modular & Multiprotocol ODL includes support for the broadest set of protocols in any SDN platform - OpenFlow, OVSDB, NETCONF, BGP and many more - that improve programmability of modern networks and solve a range of user needs. Southbound protocols and control plane services, anchored by the MD-SAL, can be individually selected or written, and packaged together according to the requirements of a given use case. A controller package is built around four key components (odlparent, controller, MD-SAL and yangtools). To this, the solution developer adds a relevant group of southbound protocols plugins, most or all of the standard control plane functions, and some select number of embedded and external controller applications, managed by policy. Each of these components is isolated as a Karaf feature, to ensure that new work doesn't interfere with mature, tested code. OpenDaylight uses OSGi (Equinox) and Maven to build a package that manages these Karaf features and their interactions.
11 / 56 ODL Architecture Modular & Multiprotocol The ODL platform is designed to allow downstream users and solution providers maximum exibility in building a controller to t their needs. This modular framework allows developers and users to: Only install the protocols and services they need Combine multiple services and protocols to solve more complex problems as needs arise Incrementally and collaboratively evolve the capabilities of the open source platform Quickly develop custom, value-added features for highly specialized use cases, leveraging a common platform shared across the industry

REST Interface 26 / 56
27 / 56 REST Interface RESTconf OpenDaylight applications expose con guration and state in the datastore. The REST interface has direct access to the controller datastore. RFC 8040 Restful API for YANG data models and provides lighter- weight interface to network datastores leveraging well known combination of REST and JSON. Con guration data and state data exposed as resources HTTP instead of SSH for transport; JSON in addition to XML for data encoding Ref: OpenDaylight as a Platform for Network Programmability

    5 / 56 ODL OpenDaylight OpenDaylight(ODL) is a modular open platform for customizing and automating networks of any size and scale. The OpenDaylight Project arose out of the SDN movement, with a clear focus on network programmability. It was designed from the outset as a foundation for commercial solutions that address a variety of use cases in existing network environments. ODL is driven by a global, collaborative community of vendor and user organizations that continuously adapts to support the industry's broadest set of SDN and NFV use cases. With over 1000 developers, 50 member organizations and supporting approximately 1 billion subscribers around the world, OpenDaylight is quickly evolving integrated toolchains for leading use cases.

  • 9.
    9 / 56 ODL Architecture Model-Driven Thecore of the OpenDaylight platform is the Model-Driven Service Abstraction Layer (MD-SAL). In OpenDaylight, underlying network devices and network applications are all represented as objects, or models, whose interactions are processed within the SAL. The SAL is a data exchange and adaptation mechanism between YANG models representing network devices and applications. The YANG models provide generalized descriptions of a device or application's capabilities without requiring either to know the speci c implementation details of the other. Within the SAL, models are simply de ned by their respective roles in a given interaction. A "producer" model implements an API and provides the API's data; a "consumer" model uses the API and consumes the API's data. While 'northbound' and 'southbound' provide a network engineer's view of the SAL, 'consumer' and 'producer' are more accurate descriptions of interactions within the SAL. For example, protocol plugin and its associated model can either be a producer of information about the underlying network, or a consumer of application instructions it receives via the SAL.
  • 10.
    10 / 56 ODL Architecture Modular& Multiprotocol ODL includes support for the broadest set of protocols in any SDN platform - OpenFlow, OVSDB, NETCONF, BGP and many more - that improve programmability of modern networks and solve a range of user needs. Southbound protocols and control plane services, anchored by the MD-SAL, can be individually selected or written, and packaged together according to the requirements of a given use case. A controller package is built around four key components (odlparent, controller, MD-SAL and yangtools). To this, the solution developer adds a relevant group of southbound protocols plugins, most or all of the standard control plane functions, and some select number of embedded and external controller applications, managed by policy. Each of these components is isolated as a Karaf feature, to ensure that new work doesn't interfere with mature, tested code. OpenDaylight uses OSGi (Equinox) and Maven to build a package that manages these Karaf features and their interactions.
  • 11.
    11 / 56 ODL Architecture Modular& Multiprotocol The ODL platform is designed to allow downstream users and solution providers maximum exibility in building a controller to t their needs. This modular framework allows developers and users to: Only install the protocols and services they need Combine multiple services and protocols to solve more complex problems as needs arise Incrementally and collaboratively evolve the capabilities of the open source platform Quickly develop custom, value-added features for highly specialized use cases, leveraging a common platform shared across the industry
