摘要
(WO201791255) A system and method for the randomization of packet headers is disclosed.  A controller is used to provide random values, also referred to as nonces, that replace the source and destination addresses that typically appear in a packet header.  The controller also provides routing rules to the switches and routers in the network that allow these devices to properly route packets, even though the source and destination addresses are not present.  In some embodiments, network devices that support software-defined networking (SDN) are employed.  The number of times that a particular nonce is used may be variable.  In some embodiments, a nonce is used for exactly one packet header.  In this way, packets may traverse a network using nonces in place of actual source and destination addresses.  Because the nonces are changed periodically, detection of traffic patterns is made significantly more difficult.

(WO201791255) 1. A method of transmitting a packet from a source to a destination in a network comprising: replacing a source address and a destination address in the packet with a set of nonces prior to its transmission; transmitting the packet from the source; sending routing rules to a network device disposed in the network, the routing rules defining the operation of the network device with respect to the set of nonces; receiving the packet at the destination; and providing the destination with the source address and destination address that correspond to the set of nonces.
