iles over the network. Differentiated Service: Architecture that is used to classify and manage traffic to provide quality of service within the network. Integrated Service: Also an architecture that is used to classify and manage traffic for providing quality of service within the network. IP Precedence: Of three bits that is used to set the priority of a packet on higher importance in case of congestion.

Quality of Service: Quality of service can be defined as network ability to achieve maximum bandwidth by dealing with network performance parameters like latency, error rate, etc. Shaping: A technique that is used to enforce lower bitrates than what the physical interface is capable of. Type of Service: It specifies a datagram's priority and request a route for low- delay, high-throughput, or highly reliable service.

B. Pant University of Agriculture and Technology, India Anushree Sah University of Petroleum and Energy Studies, India ABSTRACT The chapter surveys the analysis of all the security aspects of software-defined network and determines the areas that are prone to security attacks in the given software- defined network architecture. If the fundamental network topology information is poisoned, all the dependent network services will become immediately affected, causing catastrophic problems like host location hijacking attack, link fabrication attack, denial of service attack, man in the middle attack. These attacks affect the following features of SDN
