header ABSTRACT We describe the implementation of an OpenFlow Switch on the NetFPGA platform. OpenFlow is a way to deploy experimental or new protocols in networks that carry production traﬃc. An OpenFlow network consists of simple ﬂow-based switches in the datapath, with a remote controller to manage several switches. Enero 11, 2013 Nombre del artículo

header PROBLEM hoy se ha vuelto extremadamente difícil innovar en las redes de computadoras que usamos todos los días en las escuelas, empresas y hogares. Las implementaciones actuales de la corriente principal de los dispositivos de redes, como switches Ethernet y routers IP son típicamente plataformas cerradas que no pueden ser fácilmente modificadas o extendidas. El procesamiento y enrutamiento de paquetes se limita a la funcionalidad soportada por el vendedor. Enero 11, 2013 Nombre del artículo

header Gateware: There are two reference designs distributed with the oﬃcial NetFPGA release that run on the NetFPGA: an IPv4 router, and a 4-port NIC. All reference designs are based on a generic reference pipeline shown in Figure 4. The reference pipeline captures the main stages of packet processing in a network switch. The Rx Queues pull packets from the I/O ports, the Input Arbiter selects which Rx Queue to service, the Output Port Lookup decides which output queue to store a packet in, the Output Queues module stores packets until the output port is ready, and the Tx Queues send packets out on the I/O ports. The main switching decision usually happens in the Output Port Lookup stage and it diﬀerentiates an IPv4 router from a NIC or an Ethernet switch. We have also implemented a learning Ethernet switch which we will use for comparison in this paper. Enero 11, 2013 Nombre del artículo
