Abstract
A method includes selecting one or more green addresses, each being a different IP address from a block of IP addresses, associating the green addresses with the IP address of the server, and receiving a packet from a client directed to an IP address of the block of IP addresses. It is determined whether the destination address matches the one or more green addresses or is a yellow address. When determined that the destination address matches the one or more green addresses, the packet is sent to the IP address associated with the matching green address, bypassing any DPI. Otherwise, the packet is sent to a scrubber to analyze the packet using DPI and handle the packet or perform a redirection of the client. The redirection causes subsequent requests from the client to be sent to the IP address associated with the green address, bypassing any DPI.
