Hi everybody, we need to develop a new component to analyze all the DNS requests sent to some DNS Servers. We have similar components on our current platform (to process Radius requests, for instance), in Java or Scala but they are expected to process comparatively little traffic. This DNS analyzer would have to analyze up to 1Gbps traffic and from our experience with nProbe, PF_Ring is required when traffic is higher than 0,5Gbps, to distribute network packets among several "zc:ethX" or "dnaX" interfaces from where different processes with different core affinity consume them.
We would like to use Java or Scala development approaches, because our expertise with C is poorer, (using Netty: http://netty.io/) with our DNS analyzer in order to shorten our development time, maybe by encapsulating calls to PF_Ring API. From our experience, Netty greatly rely on network protocol stacks and I think that it would be an unbridgeable drawback. Any reference, suggestion or advice would be greatly appreciated. Thanks in advance and best regards, Manuel Polonio
