 We measured the received and mirrored packets when
increasing the send packets by “iperf –b Npps”.
 It seems that the overhead of mirroring is small if the number
of send packets is less than about 70k pps.

3.  We measured the performance of the flow based tunneling
implementation by “iperf –b Npps”.
 It seems performance is a little bit degraded compared with
previous slide.

4.  We compared between the original(community) version and
the flow based tunneling version when the UDP packet length
is 1400Byte
 It seems that the received packets with mirror and mirrored
packets are almost half of the packets without mirror, it is
because the physical network was saturated.
 Each data of flow based tunneling is almost same because of
the separation between the production and the mirror traffic.
