deep packet inspection?
 

hey guys what is the meaning of deep packet inspection? how we can do it?

As I know deep packet inspection also called complete packet inspection and information extraction or IX) is a form of computer network packet filtering that examines the data part of a packet as it passes an inspection point, searching for protocol non-compliance, viruses, spam, intrusions.

DPI is something network admins can do to investigate the nature of a TCP or UDP packet. In doing this they can find out if it is file sharing packets, DDOS, etc. despite what the packet header "says" the packet is.
