摘要： An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP's). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要： A method and system for encoding a mark-up language document is provided, in which, the structure of the mark-up language document is condensed by removing those parts of the structure that are fixed, and by expressing the variable parts of the structure in terms of whether or how often they occur. A template that specifies which parts of the structure are fixed and which parts are variable may be provided to both the device that is transmitting the mark-up language document and the device that is receiving the mark-up language document.

摘要： A method for detecting a spurious timeout in a TCP network which can be used to avoid unnecessarily triggering the TCP rate adaptation is disclosed. Upon detection of a timeout on a given packet, a shortened packet version of the possibly lost packet is retransmitted. The retransmitted packet is at least one byte shorter than the original packet. The node receiving this retransmitted packet will acknowledge the receipt of the packet as specified in the TCP protocol. The acknowledgment will contain the sequence number of the lowest byte the receiving node has not yet received. Because the retransmitted packet is shorter than the original packet, the sequence number of this as yet not received byte will be less than or equal to the last byte of the original packet if the original packet was not received indicating a valid timeout. If the sequence number in the acknowledgment is greater than the last byte of the original packet than the original packet was received correctly and the timeout was caused by a lost acknowledgment and is considered a spurious timeout. In the case of a spurious timeout the congestion control mechanisms in the TCP protocol need not be used.

摘要： A network emulator provides both per-connection and non-connection-based emulation. The emulator includes a host computer, and a kernel-mode emulator driver and user-mode application component running on the host computer. The application component supplies configuration parameters to the driver. The driver includes a packet filter list that filters a captured packet, a virtual network link that receives the packet from the packet filter list, a link group list that applies an emulation procedure to the packet, a timer management component that manages a timer associated with the emulation procedure, and a packet dispatcher component that sends out the packet. A connection pool component facilitates per-connection emulation.

摘要： A unique sync mark is applied by an encoder to the beginning of each frame in a data packet of a Windows Media™ Audio bitstream by a Microsoft® Windows Media™ Audio (WMA) codec. The WMA decoder handles errors at the frame level for each data packet. When a frame in a data packet of a WMA file is corrupted, the decoder can continue to decode the next frame by searching for the next sync mark at the beginning of the next frame. Accordingly, error propagation is confined to a single frame and the decoder can simultaneously handle bit errors and packet erasures when decompressing a received audio bitstream.
摘要翻译：唯一的同步标记由编码器应用于Windows Media TM音频（WMA）编解码器的Windows Media TM音频比特流的数据分组中每帧的开头。 WMA解码器处理每个数据包的帧级别的错误。当WMA文件的数据分组中的帧被破坏时，解码器可以通过在下一帧开始搜索下一个同步标记来继续解码下一帧。因此，误差传播局限于单个帧，并且当解压缩所接收的音频比特流时，解码器可以同时处理比特错误和分组擦除。
