Embodiment approach

[0046] At the outset, it should be understood that although an exemplary implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of known or available techniques. The present disclosure should not be limited to the exemplary implementations, drawings, and techniques shown below, including the exemplary designs and implementations shown and described herein, but rather be within the scope of the appended claims and their full range of equivalents. make changes within the scope.

[0047] The present disclosure provides various embodiments for reducing the need for packet retransmissions. In particular, this disclosure describes a packet scrubbing operation that enables an intermediate router or network node to either discard an unimportant data payload portion of a packet's payload, or add or restore a data payload portion to a packet's Payload, to modify the size of the packet midway. Packet deliver...

Abstract

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.
