A method for communicating a data packet, the method includes receiving a data packet that supports a packet wash operation. The method determines whether the data packet can be forwarded along a network path towards a destination node without any modification. If the data packet cannot be forwarded along the network path towards the destination node without modification, the method determines whether conditions are met for performing the packet wash operation on the data packet. If the conditions are met, the packet wash operation is performed to generate a washed data packet. The packet wash operation generates the washed data packet by modifying a size of a payload of the data packet based on a packet wash specification that associates attributes to a plurality of data payload portions of the payload of the data packet. The washed data packet is forwarded along the network path towards the destination node.
