Implementation of OpenFlow on NetFPGA

Abstract

Traditional networks are designed and implemented with network devices such as routers, switches, firewalls, etc. Each network device has associated functions and is configured with different standards and protocols for packet transmission. But this traditional model is not the only one that exists, today is beginning to impose a new model of software-defined network, known as SDN (Software Define Networks). While SDN also uses the same network devices, the diiTerence is that these networks are using the advantages of programming software, which means to use a universal control interface; this interface Controls the network devices and progTam delivery services or rou-ting packets. This artide presents the advantages of SDN over the traditional networks and displays basic performance tests conducted in a laboratory environment with implementing OpenFlow in a NetFPGA card, in contrast to performance tests conducted with commercial network devices.
