作者好:
1,根据文档好像是为1g宽带做做的,而我的带宽只有1m,而中国大部分adsl用户也只有2m到4m,所以希望作者考虑一下国内的情况,能针对不同的低带宽有所优化,建议在传输过程中udp能不段优化对实际带宽的估计,然后有针对性的优化应的发包调节粒度...

I use libevent in my application, which manages watching for changes on file descriptors, signals, and timeouts for most of my application's components, but not for UDT. Because UDT is at the application level, kernel calls like select() don't operate on UDT's sockets, so my application has to periodically check on the status of UDT with for instance UDT::selectEx() with msTimeOut=0.
I'm...

如果只需要5秒钟，可以只用下面一个条件
if (m_iEXPCount * ((m_iEXPCount - 1) * (m_iRTT + 4 * m_iRTTVar) / 2 + m_iSYNInterval) > 5000000)

if (currtime > m_ullNextEXPTime)
{
// Haven't receive any information from the peer, is it dead?!
// timeout: at least 16 expirations and must be greater than 3 seconds and be less than 30 seconds
if (((m_iEXPCount > 16) && (m_iEXPCount * ((m_iEXPCount - 1) * (m_iRTT + 4 * m_iRTTVar) / 2 + m_iSYNInterval) > 3000000))

Hi,
I'm running UDT 4.6 on Linux with async sockets. However when using "select" to query sockets for being readable, my program uses about 5 to 10% CPU even if the sockets are not readable and the call to "select" times out (30 seconds). The list of sockets contains only two entries. Is there anything I need to setup to reduce the load?
Best regards,
Joachim.

用recvfile接收服务器传下来的文件，如果服务器非正常退出（比如掉线），那么客户端需要60秒才能收到connection broken的信息，请问谷先生这个超时的时间应该在哪里更改？.

本人在调试中发现了udt运行时出现内存异常。（Windows 平台）
怀疑是跨dll访问stl对象引起的。
UDT中select 和 selectEx函数的参数 readfds, writefds, exeptfds是stl对象的指针跨dll传递。
请问这是否存在问题？有什么最好的解决方案？.
