But as networks get flooded with millions of unwanted e-mail, peer-to-peer traffic, and denial of service attacks, network operators need tools to control how much traffic comes onto their networks. "Adding intelligence in the network will cause a lot of these problems to go away," Christy said. "It's much more effective to simply control who gets access to the resources.". The TurnTide router works by using a basic feature of TCP/IP: the "handshake" method. When a packet is sent to a destination, the source waits for a confirmation that the packet has arrived. If the confirmation packet is delayed, the source will stop sending more packets. It will continue sending test packets until it gets a response. Once the handshake has been completed, the source sends the rest of the packets in the stream.

By controlling the confirmation response, TurnTide can limit how much traffic is being sent from a particular source, Because most spam applications are impatient, they will give up and stop trying to send mail after a short period of time, In contrast, legitimate mail servers will continue to send test packets until they get a confirmation, Network administrators can also tune the TurnTide box so nevertheless, she persisted. iphone case that traffic that is known to be from a good source gets a rubber stamp of approval and is allowed to come through without being rate-shaped at all..

"Because we control the resources on the network, there is a real practical limit on how many e-mails a spammer can send," said David Brussin, the chief technology officer at TurnTide. "The spam business is based on volume, so if they can't get millions of messages through, they'll go somewhere else.". The TurnTide method has its drawbacks. Because the device must learn the characteristics of the traffic, it still allows some spam messages to get through the network. Brussin recommends that network operators continue using spam filters to catch this trickle of junk mail. He argues that by reducing the overall amount of spam on the network it will help spam filters work more efficiently, because they have fewer messages to examine.
