The analysis of time reaction in OpenFlow switches in NetFPGA cards and ROFL

In this paper we present the results of the delay measurements of the Ethernet traffic handled by different Open-Flow switches realized in the NetFPGA cards. We investigated three different software approaches: reference software for Open-Flow on NetFPGA cards, xDPd/ROFL prepared for OpenFlow implementation in NetFPGA cards and xDPD/ROFL library prepared for GNU/Linux cooperating with reference NIC with four ethernet ports realized on NetFPGA cards. All three cases have been realized on two versions of the NetFPGA cards - with 1G and 10G ports.
