    摘要： A method and a network device for achieving end-to-end latency guarantees, where the method includes: receiving, by a network device in a core network, a latency guarantee service (LGS) request message from a source node in a data network (DN), the LGS request message requesting to transmit traffic to an end device and comprising one or more of a LGS indicator, an end-to-end packet delay budget (PDB) requirement, a maximum flow rate, and an end device identifier; determining a remaining PDB for the core network and a transport network; sending an LGS slice selection request to a network function, including one or more of the remaining PDB, the maximum flow rate, and the identifier; and receiving an LGS response from the network function, which identifies an LGS slice for the requested traffic and indicates whether the LGS slice is able to satisfy the remaining PDB and the maximum flow rate.

    摘要： 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.

    摘要： A media data coding mechanism is disclosed. The mechanism includes partitioning media data into a plurality of blocks. A transform is applied to the blocks to obtain a plurality of quantization coefficients. The quantization coefficients are sorted into quality layers of decreasing priority based on frequency, wherein each subsequent layer includes data to incrementally increase quality of a reconstructed media data. Quantization coefficients for all blocks are positioned in a media data packet according to quality layer in order of decreasing priority. The media data packet is stored.
