The design teams similar communication functions into considered one of seven rational levels. A layer serves the layer higher than it and is served from the layer down below it. For example, a layer that provides error-no cost communications throughout a network provides the communications route necessary by purposes over it, though it phone calls the subsequent lower layer to mail and obtain packets that traverse that route.
The primary purpose of an attacker which is leveraging a Denial of Assistance (DoS) attack method would be to disrupt a web site availability:
[seventy three] Most gadgets with a network will, by default, reply to this by sending a reply to the resource IP handle. If the quantity of equipment to the network that get and respond to these packets may be very significant, the sufferer's Laptop will likely be flooded with website traffic.
