4. What is OpenDaylight?

8. OpenDaylight
Overview
• Software-Defined
Networking (SDN)
• Modular controller at core
• Northbound APIs to apps
• Southbound interfaces to
network devices

9. • Java chosen as an enterprise-grade,
cross-platform compatible language
• Git – version control system
• Maven – build system for Java
• OSGi:
• Enables dynamic loading of feature bundles
• Can register dependencies and services exported
• Infrastructure for exchanging information across bundles
• Karaf: Light-weight Runtime for loading modules/bundles
• OSGi based. Primary distribution mechanism for Helium
OSGi Framework (Equinox)
FeatureA
SAL
FeatureB
…
Karaf
OpenDaylight - Java, Git, Maven, OSGi and Karaf

10. • Based on modern frameworks:
node.js, AngularJS
• Completely decoupled from the
core controller
• Run it from any location
• Modular, easy to extend
OpenDaylight – the DLUX UI

11. Where to Get Open Daylight
• It’s Open Source !
• The Easy Way - Download and Play (unzip and run)

16. ODL NETCONF Plug-In
Controller Config
MD-SAL
NETCONF
NETCONF
• Mounted under e.g. http://localhost:8181/restconf/config/opendaylight-
inventory:nodes/node/controller-config
• Data can be accessed using …/yang-ext:mount/…
• …/yang-ext:mount/config:modules is used to configure the various plug-ins
Config Store
RESTCONF

17. ODL NETCONF Plug-In
Node “Discovery”
MD-SAL
NETCONF
RESTCONF
Node Inventory
• Nodes added by POSTing to config:modules
• ODL connects to each node
• ODL learns capabilities (YANG modules) and stores to model cache
• Cache at ~/cache/schema. Filenames of form yang-model@2015-09-03.yang.
Model Cache
XR1 XR2 OpenWRT

18. ODL NETCONF Plug-In
Node Configuration
MD-SAL
NETCONF
RESTCONF
Node Inventory
• Nodes configured by POSTing or PUTting to e.g.:
• http://localhost:8181/restconf/config/opendaylight-inventory:nodes/node/XR2/yang-
ext:mount/Cisco-IOS-XR-ifmgr-cfg:interface-configurations/interface-
configuration/act/Loopback0/
• Can retrieve config (or operational stats) using GET
Model Cache
XR1 XR2 OpenWRT

19. RESTCONF
• ReSTful protocol to access YANG defined data
• Remote State Transfer, i.e. server maintains no session state
• HTTL URLs reflect data hierarchy in a YANG-modelled datastore
RESTCONF Netconf
GET <get-config>, <get>
POST <edit-config> (“create”)
PUT <edit-config> (“replace”)
PATCH <edit-config> (“merge”)
DELETE <edit-config> (“delete”)
OPTIONS (discover supported operations)
HEAD (get without body)
