DAG high performance network cards
Posted by creining | Filed under Security
I recently read about the use of DAG cards for high volume network traffic capture. I found out that they are manufactured by endace and that the network cards, according to endace, are “specifically designed for network surveillance applications”. From the graph they provide on packet loss between different cards it appears that they perform superiorly. Of course, that graph doesn’t represent independent testing but it is intriguing nevertheless. Their product page states that DAG cards can be used with some popular applications such as libpcap, tcpdump, snort, and ntop. The site does mention though that DAG cards are only supported on “Linux 2.4 and FreeBSD 4, to which Linux 2.6, FreeBSD 5 and Microsoft Windows XP/2003 Server (with WinPCap support) will be added shortly.” It would be interesting to get my hands on one of these DAG cards to test it out.
