Silly window syndrome (SWS) is a problem in computer networking caused by poorly implemented TCP flow control. A serious problem can arise in the sliding window operation when the sending application program creates data slowly, the receiving application program consumes data slowly, or both. If a server with this problem is unable to process all incoming data, it requests that its clients reduce the amount of data they send at a time (the window setting on a TCP packet). If the server continues to be unable to process all incoming data, the window becomes smaller and smaller, sometimes to the point that the data transmitted is smaller than the packet header, making data transmission extremely inefficient. The name of this problem is due to the window size shrinking to a "silly" value.

- 糊涂窗口综合症（Silly window syndrome），亦称愚蠢窗口综合症、愚笨窗口综合症，是TCP实现不良导致的一种计算机网络问题。当发送程序缓慢地生产数据，接收程序缓慢地消耗数据，或者两者同时存在时，滑动窗口运作会出现严重问题。如果一个服务器无法处理所有传入的数据而存在此问题，它会要求客户端减少一次发送的数据量（TCP網路封包的滑动窗口）。如果服务器仍然无法处理所有传入的数据，窗口会随此问题越来越小，有时甚至将使传输数据小于数据包头，使数据传输变得极为低效。这个问题的名字取自窗口缩小到“愚蠢”的值。当该综合症发生时，连接上交换的数据段是小数据段而不是全尺寸的数据段。 基于窗口的流量控制网络协议，特别是使用非固定段大小的（例如TCP），都有可能陷入糊涂窗口综合症。 处理每个封包都存在一定量的，封包数增加会增加网络通信的开销，可能使数据处理量进一步减少。最终的结果就是。 (zh)

| - Silly window syndrome (SWS) is a problem in computer networking caused by poorly implemented TCP flow control. A serious problem can arise in the sliding window operation when the sending application program creates data slowly, the receiving application program consumes data slowly, or both. If a server with this problem is unable to process all incoming data, it requests that its clients reduce the amount of data they send at a time (the window setting on a TCP packet). If the server continues to be unable to process all incoming data, the window becomes smaller and smaller, sometimes to the point that the data transmitted is smaller than the packet header, making data transmission extremely inefficient. The name of this problem is due to the window size shrinking to a "silly" value. Since there is a certain amount of overhead associated with processing each packet, the increased number of packets means increased overhead to process a decreasing amount of data. The end result is thrashing. (en)
