    摘要： Disclosed is system and method to implement an on-demand file repair protocol. In the protocol, a traffic source sends all data packets of a data file to a traffic sink. The traffic source then sends to the traffic sink an indication that the sending of the all data packets is complete. If data packets are missing, a request is received from the traffic sink for retransmission of missing packets. The traffic source then sends fountain codes of the missing packets to the traffic sink.

    摘要： Methods and systems for determining placement of a virtual serving gateway. The method includes obtaining a set of input information. The input information includes network information and configuration information providing one or more parameters for placing the virtual serving gateway, and includes at least one mobility insensitivity criterion. Placement of the virtual serving gateway at one or more physical hosts is determined in accordance with the network information and the configuration information. The virtual serving gateway is distributively placeable across physical hosts. A set of output information is generated. The output information includes information identifying placement of the virtual serving gateway at the physical hosts, and a hosting percentage for each physical host.

    摘要： Real-time video can be efficiently and reliably streamed over wireless networks by fountain encoding a stream of video packets at the frame-level. Specifically, deep packet inspection may be performed on the stream of video packets to identify a set of video packets corresponding to an intra-coded frame (I-frame). The set of video packet may then be fountain encoded together as a data segment to produce a set of fountain encoded packets corresponding to the I-frame. Video packets corresponding to other frames (e.g., P-frames, etc.) may also be encoded on a frame-by-frame basis. This may allow a user equipment (UE) to begin displaying earlier frames in a group of pictures (GoP) while fountain encoded packets for subsequent frames are still being received, thereby reducing latency and improving the overall user experience.
