1.The most important consortium involve in SDN standardization is the Open Network Foundation (ONF). The most important contribution is OpenFlow protocol and API.

2. OpenDaylight Helium consists of dynamically pluggable modules such as topology, statistics, forwarding rules, and switch managers.

3. OpenDaylight is both a protocol between SDN controller and network devices and a specification of the logical structure of the network switch functionality.

4. Representation State Transfer (REST) is an architectural style constraints used to define APIs for constructing southbound API for SDN controllers.

5. Action can be defined as packet forwarding, packet modification, and group table processing operations.

6. Group table and group actions enable OpenFlow to represent a set of ports as a single entity for forwarding packets, such as multicasting and broadcasting.

7. SDN controller layer maps application service requests into specific commands and directives to the data plane switches and supplies applications with information about data plane topology and activities.

8. SDN Controller plane contains application and services that defined, monitor, and control network resources and behavior.

9. Abstraction is the amount of detail about the lower levels of the model that is visible to the higher level. More abstraction mean less detail.

10. An abstraction layer is a mechanism that translate a higher-level request into the low-level commands required to perform the request.

11. A network abstraction represents the basic properties or characteristic of network entities (switch, link, port, and flow).

12. Frenetic is an example of a network services layer, which enable network operators to program the network as a whole instead of manually configuring individual network elements. Similar to SQL. Includes segment for selecting, filtering, splitting, merging, and aggregating the streams of packets. Also enable query to composed with forwarding policies.

13. Traffic engineering is a method for analyzing, regulating, and predicting the behavior of data flows to optimize performance.

14. Defense4All is a traffic engineering SDN application that detects violations and remediates violations.

15. PolicyCop is SDN security application that offers DDOS protection by detecting differences from baseline conditions.

16.The goal of CloudNaaS is to give customers increased control over their providers network.

17. Information-centric networking is decoupling information and sources to provide efficient information retrieval.

18. Content packet in CCNx requests content for CCNx, where Interest packet satisfies the request from an content packet.
