Cisco Open SDN Controller

AB.

The Cisco Open SDN Controller is a commercial distribution of OpenDaylight that delivers business agility through automation of standards-based network infrastructure.

It abstracts away the complexity of managing heterogeneous network environments to improve service delivery and reduce operating costs.

As open-source-based software, the Open SDN Controller continuously advances through ongoing innovation and support of the OpenDaylight community.

The Cisco Open SDN Controller is a software-defined networking (SDN) controller that enables network administrators to manage and automate network functions. It is an open-source controller that provides an open and programmable network infrastructure for agile application delivery and enhanced network automation. Below are the two true statements about the Cisco Open SDN Controller:

A. It is a commercial distribution based on the OpenFlow controller: This statement is false. The Cisco Open SDN Controller is not a commercial distribution based on the OpenFlow controller. It is an open-source controller that supports OpenFlow, NETCONF, and other southbound protocols to program the network infrastructure. Therefore, this statement is incorrect.

B. Your own, new network service functions can be added via Java APIs: This statement is true. The Cisco Open SDN Controller provides a comprehensive set of northbound APIs that enable network administrators to create and add their own network service functions. The APIs are written in Java and provide a simple and flexible interface for network automation. Therefore, this statement is correct.

C. Security is enforced by using the Open Services Gateway Initiative framework: This statement is false. The Open Services Gateway Initiative (OSGi) framework is not used to enforce security in the Cisco Open SDN Controller. Instead, the controller provides security mechanisms such as role-based access control (RBAC) and secure transport protocols to ensure network security. Therefore, this statement is incorrect.

D. It can be used in multivendor environments: This statement is true. The Cisco Open SDN Controller is designed to work in multivendor environments and supports a wide range of networking devices from different vendors. It provides a vendor-agnostic platform for network automation and orchestration, enabling network administrators to manage and automate their networks seamlessly. Therefore, this statement is correct.

E. The controller is available as an appliance only: This statement is false. The Cisco Open SDN Controller is not available as an appliance only. It can be deployed as a virtual machine or installed on a physical server, providing flexibility in deployment options. Therefore, this statement is incorrect.

In conclusion, the two true statements about the Cisco Open SDN Controller are:

• Your own, new network service functions can be added via Java APIs.
• It can be used in multivendor environments.
