Question:
SYN Attack. How large must be server's memory be to withstand a SYN attack? To answer this, suppose the following:
- Suppose that the initial value of RTO is 3 sec., and RTO is multiplied by two if a packet loss occurs.
- Suppose that a TCP server will only resend a SYN-ACK four times if an ACK does not arrive before RTO after the previous SYN-ACK was sent.
- Suppose that the server reserves 100KB of memory when a SYN arrives, and frees the memory after the connection ends, the connection is reset, or the connection fails (e.g., if no response for the SYN-ACK arrives after four retries).
- Finally, suppose that the server is connected via a 10-Mbps link and SYN packets are 40B.
