Abstract
Description
With rapid development of information technology, information security becomes more and more important in enterprises, governments and service providers networks. As we are transferring from traditional networks to SDN (Software Defined Network), the IT budget will be reduced dramatically due to the cutting cost of purchasing expensive security devices and deploying security services. In contrast with traditional networks, SDN offers centralised management, flexible deployment and programmability. Some SDN controllers were created to take the advantage of SDN’s flexibility, but it is not flexible to add new modules with designated firewall functions on these controllers. A new network programming language, Pyretic, was
developed to solve this problem. (As cited in abstract.)
