ow, monitoring and controlling of data packets, developers created a map for automation in networking domain in decade of 90's. According to growth of the network the map is pictorially represented as shown in Figure 1. To explain standards and working of SDN, Open Networking Foundation (ONF) developed a multivendor standard which is known as OPEN FLOW (N. McKeown et al., 2008). Often term standard is replaced with protocol in networking. So OPEN FLOW defines an interface protocol which works between Open flow controller and Open flow switch. Open flow architecture. Open flow switch contains following functionalities: Downloaded: 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 Learning With Software-Defined Area Figure 1. Open flow protocol with 1.3.0 switch specification Open Flow Controller Secure Channel Group Table Flow Table Flow Table Identification of data packets and categorizes them based on packet header information. Processing and modifications inside those packets. Option selections based on drop the packet or push the packet towards destination machine. Like open flow protocols, there are many programmable effort are performed by developers. In this section we will represent some popular standards used in programmable network approach. To implement programmable open flow switch IETF (Internet Engineering Task Force) implemented specific protocol called as General Switch Management Protocol (GSMP). This protocol is an asymmetric protocol and used for maintenance of states of labeled switches like frame relay, ATM etc. Network configuration protocol is a network management based protocol which was developed by NETCONF working group. Functionality of network group is categorized into four layers (refer to Figure 2), which are as follows: Downloaded 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 Learning With Software-Defined Area Figure 2.
