Discarded packet indicator

摘要

A source device (10) sends information to a destination device (12) through intermediary network elements (14). If an intermediary network element (14) needs to discard one or more packets of information, it sends a smaller informational packet to the destination device (12). Upon receiving the informational packet, the destination device can immediately begin correctional procedures.

1. A network comprising:
a source device for sending information; a destination user device for receiving the information from the source device; and one or more intermediate network elements for passing the information between the source device and the destination user device, wherein each of the intermediate network elements include circuitry for:
identifying at least one packet, having a header and a payload, within the information for discard based on a payload a video packet priority indicator within the header;modifying the header of the at least one identified packet to include a discard indicator, and modifying the at least one identified packet to remove the payload, thereby forming at least one modified packet; andsending the at least one modified packet to the destination user device.
