通常，流控制传输协议（SCTP）延迟数据段的发送。对于特定情况，这会导致非最佳协议行为。因此，协议规范定义了几种例外情况，允许包含用户数据的SCTP分组的接收方发送相应的确认而不延迟它，但所有这些例外情况都只考虑了用户数据接收方的状态，因此不能涵盖所有相关情况。为了克服这种限制，作者提出了一种通用机制，允许包含用户数据的SCTP分组的发送方指示相应的确认不应被延迟。本文分析了在几种情况下使用这种发送方机制的好处。
In general, the Stream Control Transmission Protocol (SCTP) delays the sending of acknowledgments. For specific cases, this results in non-optimal protocol behavior. Therefore, the protocol specification defines several exceptions that allow the receiver of an SCTP packet containing user data to send the corresponding acknowledgment without delaying it. However, all these exceptions only take the status at the user data receiver side into account and thus cannot cover all relevant situations. To overcome this limitation, the authors have proposed a generic mechanism allowing the sender of an SCTP packet containing user data to indicate, that the corresponding acknowledgment should not be delayed. This paper analyzes the benefits of using this sender side mechanism under several conditions.
