cation data Operational Layer Edit-conf. Message Layer <pc>, <pe-replay> Notification SSH, TLS Secure Transport Layer For configuration and notification of data content layer is responsible. Operation, retrieval, editing of data is functionality of Operational layer. Encoding of remote procedural calls and notification is provided by Message layer. Forsecurity and reliability of data delivery Secure Transport Layer is responsible (Casado et al., 2006) Some of the open sources to implement the SDN are described in the following table (refer Table 1). Table 1. Open sources for implementing SDN with description S. No. Tool Name Description and Availability of Tool Apache licensed and java based application. Application of Open Flow protocol over virtual and physical Floodlight switches. Controls to switch forwarding tables, traffic monitoring and controlling. Work with physical and hypervisor switches both. Application of hardware abstraction layer(HAL) and set of Indigo network libraries for integration and management of network and controlling the network traffic. Developed as cloud network controller (M. Casado et al, Open Stack Networking 2007) Neutron Focusing on network as a service (NaaS) Multiple layer based switch used for network virtualization. Open V Switch Based on application of Netflow, sFlow etc. Includes services of Linux kernel 3.3 Based on Linux services but platform independent OpenDaylight Support of OpenFlow protocol Downloaded: 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 Learning With Software-Defined Area ARCHITECTURE OF SOFTWARE DEFINED NETWORKING Development of Software defined networking is started from development of java era. One main reason of this growth was compatible nature of Java, which shows that how effectively java well suited with distinct interfaces written in different platforms and languages. SDN working is based on two important platform components. These are network and topology virtualization. These both components develop customized collect
