This and the technological evolution leads to traffic which is becoming more and more important. With the increasing bandwidth, the observation and control of the traffic also needs to be accomplished at a higher speed. This new challenge is being encountered by using hardware implementations of monitoring algorithms.<\/p>\n<p>During our third-year project at T\u00e9l\u00e9com Bretagne we worked on such a hardware implementation using a NetFPGA, a PCI board containing an FPGA and four Ethernet ports. Starting with a simple Ethernet hub that we added to the existing structure of the NetFPGA, we continued with the implementation of a detection of TCP SYN packets. In order to count these SYN packets, needed for the detection of SYN \ufb02ooding attacks, we used a special stream mining algorithm to reduce the memory needed : the CMS algorithm.<\/p>\n<h3>More information<\/h3>\n<p>Everything we did about this project is available online <a title=\"NetFPGA project Trac (in French)\" href=\"http:\/\/trac.benoute.fr\/netfpga\">on the Trac of our project<\/a>. <a title=\"NetFPGA project final report (in French)\" href=\"http:\/\/trac.benoute.fr\/netfpga\/raw-attachment\/wiki\/Livrables\/rapport_technique.pdf\">The final report<\/a> is also available (in French, sorry).<\/p>","protected":false},"excerpt":{"rendered":"<p>During my third year at T\u00e9l\u00e9com Bretagne, I worked on a project with two colleagues to develop an hardware accelerated network monitoring tool using a NetFPGA.
