Dear Carlos and Iwase,
Thank you very much for your kind response. After reading another papers
about DPI, I found that this process will have a lot of delay for packet
inspection process. Actually, by using SDN, I would like to decrease the
delay, especially for specific traffic. So I am thinking DPI is not fit to
my aim.
After searching some sources, now I am thinking to use Network Function
Virtualization (NFV) to achieve this purpose. I am thinking to send the
traffic flows to a node which enabling NFV at the edge of the network. In
the NFV node, there will be traffic classification and put some marks in
the headers of these traffic flows. What do you think about this methods?
maybe some friends have experienced to combine NFV and SDN. every input are
welcome, thank you
regards,
lisa
