摘要

多媒体传输中允许的延迟是影响媒体同步的重要因素。自动重复请求(ARQ)是一种非常流行的纠错协议。然而，较长的传播延迟和较高的包错误率会导致较长的总包延迟。如果接收到的数据包的延迟比允许的延迟长，那么它将丢失。这种损耗降低了多媒体应用程序的质量。为了解决这一问题，提出了一种自适应协议中继能力。有了这个功能，协议就可以在中继节点上自适应地终止。但是，协议中继节点之间的纠错仍然需要较小的延迟。分析了协议中继能力与允许延迟的媒体传输总损耗之间的关系。此外，还描述了该自适应协议中继的标准。

Adaptive protocol relay capability with allowable delay of media transmission

Allowable delays in multimedia transmission are an important factor for media synchronization. Automatic repeat request (ARQ) is a very popular protocol for error correction. However, long propagation delays and high packet error-rates make long total packet delays. If the received packet has a longer delay than the allowable delay then it will be lost. This loss reduces the quality of the multimedia applications. To solve this problem, an adaptive protocol relay capability is proposed. Having this capability allows the protocol to be adaptively terminated at the relay nodes. However, the error correction between the protocol relay nodes still requires a small delay. We analyze the relationship between the protocol relay capability and the total loss of media transmissions with allowable delay. Also, the criteria for this adaptive protocol relay is described.
