Question

我遇到的罕见头痛问题真的需要一些好的解决方案。

背景是为了满足客户的要求，我开发了一个FileTransfer wcf服务，用于在互联网和企业内部网之间传输文件，因此我使用Windows服务通过提供两个协议来托管它，http和tcp，前者用于互联网内部网的数据传输和后者。但是，不幸的是，Windows服务主机处于恶劣的网络状态，更具体地说，它会随机丢失连接。

为了传输大文件的意图，我将sendtimout，receivetimeout，opentimeout和closetimeout设置为比较大的值，如“00:30:00”，但有时如果连接丢失或不稳定，则必须等待很长一段时间的发送 - 响应。

任何想法或棘手的解决方案？
