Abstract:
1. A method for use by an encoding node configured for encoding packets for transmission toward a decoding node, the method comprising: receiving, at the encoding node, a control packet of the decoding node, the control packet identifying a reference packet stored in a packet cache of the encoding node that is missing from a packet cache of the decoding node; processing the reference packet stored in the packet cache of the encoding node in a manner for preventing use of the reference packet by the encoding node for encoding packets for transmission to the decoding node; identifying, at the encoding node, a region of a target packet that matches a region of the reference packet stored in the packet cache of the encoding node; and preventing replacement of the region of the target packet with an encoding key identifying the reference packet based on a determination that the reference packet is marked in a manner indicating that the reference packet is not to be used for encoding.
