Abstract: Described herein are various principles for operating transfer protocols using adaptive flow control techniques. In accordance with some of these principles, a client may adaptively negotiate with a server regarding a window size to use when communicating datagrams using a connectionless content unit transfer protocol like the Trivial File Transfer Protocol (TFTP). In some implementations, a client may inform a server whether to increase or decrease a window size. In these implementations, the client may increase the window size upon determining that a previous window size has led to successful transfer of content without any loss of datagrams and the client may decrease the window size upon detecting a loss of a datagram. Because of the limited resources available in some environments in which these techniques may be used, in some implementations a window size may be increased by small amounts but may be decreased drastically upon detecting a loss.

Abstract translation: 这里描述了使用自适应流控制技术来操作传送协议的各种原理。 根据这些原理中的一些原则，当使用无连接内容单元传输协议（如简单文件传输协议（TFTP））传送数据报时，客户端可以自适应地与服务器协商关于使用的窗口大小。 在一些实现中，客户端可以通知服务器是否增加或减小窗口大小。 在这些实现中，客户端可以在确定先前的窗口大小已经导致内容的成功传送而没有任何数据报的丢失的情况下增加窗口大小，并且客户端可以在检测到数据报的丢失时减小窗口大小。 由于在可以使用这些技术的一些环境中可用的资源有限，在一些实现中，窗口大小可以增加少量，但是在检测到丢失时可能会急剧下降。
