Final answer:
OpenFlow, OnePK, and OpFlex are Southbound Interfaces (SBIs) used to manage and communicate with network devices, while RESTCONF and REST are usually considered Northbound Interfaces, and OSGi is a Java framework not directly related to SBIs.
Step-by-step explanation:
The terms in the question that are Southbound Interfaces (SBIs) include the following:
- OpenFlow - It is a protocol designed to manage and interact with flow tables in a network switch or router.
- OnePK - Cisco's One Platform Kit (OnePK) is a set of APIs that allow developers to access the internals of Cisco network hardware.
- OpFlex - This is a protocol that communicates policies to be implemented on a network device; it's part of Cisco's Application Centric Infrastructure technology.
In contrast, RESTCONF and REST are commonly associated with Northbound Interfaces (NBIs), facilitating communication between software applications and the network, rather than between network devices themselves. OSGi (Open Service Gateway initiative) is a Java framework for developing and deploying modular software programs and is not specifically related to network device configuration like SBIs are.
