OpenDaylight Project Goals

Code: To create a robust, extensible, open source code base that
covers the major common components required to build an SDN
solution

Acceptance: To get broad industry acceptance amongst vendors
and users

Community: To have a thriving and growing technical community
contributing to the code base, using the code in commercial products,
and adding value above, below and around.

Standardization Asks

Controller’s NB API:
 Address Space: the whole network as opposed to an NE
 Policies (access, address space remaps, views, request
routing)

Application requirements:
 I2RS (defining requirements)

NETCONF:
 RESTConf
 Efficient binary encoding (e.g. draft-varga-netconf-exicapability)
 JSON encoding
 Query language

Standardization Asks (Yang)

Yang ODL extensions (e.g. request routing, Java API
generation)

Yang programming language bindings (Java, Python, ...)

Standard Service Models:


Example: VPNs, DDoS, QoS, Topology, ...
Standard Device Models:

Example: IP, ACL, RIB,

WADL/RSDL for RESTCONF clients

Yang as IDL
