    • Embodiments of the invention disclose a method, apparatus and system of translating a source binary code into a target binary code. The translation according to embodiments of the invention may include determining whether or not a previously translated code block that relates to a source fragment to be currently translated may be reused for execution by a target processor. A reusability status of the previously translated code block may be determined based on a reusability status of a group of previously translated code blocks. In some embodiments, when no previously translated code blocks relating to the currently translated source fragment are found, the source fragment may be translated into a new target code block, which may be executed by the target processor. The new target code block may then be added to a group of previously translated code blocks.
    • 本发明的实施例公开了将源二进制代码转换为目标二进制代码的方法,装置和系统。 根据本发明的实施例的翻译可以包括确定与当前被翻译的源片段有关的先前翻译的代码块是否可以重用于目标处理器执行。 可以基于一组先前翻译的代码块的可重用性状态来确定先前翻译的代码块的可重用性状态。 在一些实施例中,当没有找到与当前转换的源片段相关的先前翻译的代码块时,源片段可以被转换成可以被目标处理器执行的新的目标代码块。 然后可以将新的目标代码块添加到一组先前转换的代码块。

    • Media processing of real-time protocol (RTP) packets used in time sensitive applications makes efficient use of network resources, e.g., by dropping or resizing the packets, but hinders measuring and reporting end-to-end reception quality. Because media processing causes a difference between what is sent and received, end-to-end reception quality cannot be measured validly without accounting for this difference. Accordingly, a method and corresponding apparatus are provided to track changes to RTP packets of an RTP session caused by media processing, modify RTP packet information of the RTP packets based on the tracked changes, correct RTP control protocol (RTCP) packets corresponding to the RTP session based on the tracked changes, the corrected RTCP packets being a measure of the end-to-end reception quality of the RTP session, and report the end-to-end reception quality of the RTP session by forwarding the corrected RTCP packets. Thus, end-to-end reception quality can be validly measured and reported.
    • 在时间敏感应用中使用的实时协议(RTP)分组的媒体处理使得有效利用网络资源,例如通过丢弃或调整分组大小,但是阻碍测量和报告端到端的接收质量。 由于媒体处理造成发送和接收的差异,端到端接收质量无法有效测量,而不考虑这种差异。 因此,提供了一种方法和相应的装置来跟踪由媒体处理引起的RTP会话的RTP分组的变化,基于跟踪的改变来修改RTP分组的RTP分组信息,对应于RTP的正确的RTP控制协议(RTCP)分组 会话基于跟踪的变化,校正的RTCP分组是RTP会话的端对端接收质量的量度,并且通过转发校正的RTCP分组来报告RTP会话的端到端接收质量。 因此,可以有效地测量和报告端到端的接收质量。

    • Media processing of real-time protocol (RTP) packets used in Voice over Internet Protocol (VoIP) and other time sensitive applications makes efficient use of network resources, e.g., by dropping or changing the size of certain packets, but hinders measuring and reporting end-to-end reception quality. Because media processing changes RTP packets between a sender and receiver, causing a difference between what is sent and received, end-to-end reception quality cannot be measured validly without accounting for these changes. Accordingly, a method and corresponding apparatus are provided to track changes to RTP packets of an RTP session caused by media processing of the RTP packets, modify RTP packet information of the RTP packets based on the tracked changes, correct RTP control protocol (RTCP) packets corresponding to the RTP session based on the tracked changes, the corrected RTCP packets being a measure of the end-to-end reception quality of the RTP session, and report the end-to-end reception quality of the RTP session by forwarding the corrected RTCP packets.
