Inode key value structure, this file gets the IP Four tuple combination is socket level address, in order to determine the direction, need to use Ipgroup-dir Store orientation information, {local_addr+remote_addr:1} indicates uplink (upload) and {Remote_addr+local_addr:2} represents the downstream (download). Ipgroup-payload The key value structure of IP four-tuple and packet load is obtained by Pcap packet , and the Ipgroup obtained by this method is TCP/IP Ipgroup of the protocol layer , ge
