Suppose that Bulk, an online retailer, is subjected to a distributed denial of service (DDOS) attack. Bulks web retail system is comprised of 100 web servers and the attacker recruits 50 zombie devices to constantly send 60-byte SYN packets to the Bulks web servers.

Suppose that each of Bulks servers maintains a table for 256 TCP connection requests, and that in response to a SYN, these servers send a SYN-ACK packet four times, at t = 32 second time intervals, then purge the request from the table if no reply is forthcoming.

1) In packets/second what is the rate at which SYN packets will fill Bulks connection tables?
