The phone company keeps a record of every incoming and outgoing call on every line, and performs all sorts of analysis on time of day and carrier, and who gets paid for it. [...] ISPs need to spend the money to make this a reality and keep accounting data for at least several days or a week.
The volume of IP datagrams exceeds the volume of calls worldwide by orders of magnitude. The cost of a router is orders of magnitude lower than the cost of a phone switch. The quantity of data required to log all packets going by is only about a factor of ten less than the total data crossing the network. Imagine the size of the disks involved. In sort, this is not the way to stop SYN attacks. Perry
