Abstract
A method and system for protection against denial of service attacks to a server coupled to a network. The server may establish connections with client computers through the network. Packets are received over the network directed to the server. It is determined whether the packets are associated with an established connection. The packets associated with the established connection are separated for processing by the server in a first buffer. The packets requesting a new connection are separated in a second buffer. The packets in the second buffer requesting a new connection are serviced at a lower priority than the packets relating to established connections.
