1. @huayangchan # 914
Download the source code of Layotto-0.5.0. When compiling and starting on the local Windows system, some undefined functions and variables are reported, such as undefined: syscall.GetsockoptIPv 6Mreq. This should be a function called only by the Unix system. Why is it called when running on the Windows system? Functions related to the Unix system, and it is said that the source code can only be started on the Unix system?
A: Layotto is based on MOSN and uses Linux system functions, so it does not support compiling on Windows. You can refer to: https://github.com/mosn/layotto/issues/801

The picture shows the online and offline process of the instance (Client). Assuming such a scenario, Client1 is in the offline process. At this time, it has disconnected from the Session Server, but the Session Server hangs up for some reason before sending out the synchronization notification. How is the state of Client1 in the routing table maintained?
A: There is a timer on Data to maintain data related to each Session. If the session hangs up, Data will clean up the data of the hung up session after about 30 seconds, and the client (except the one to be offline) will be automatically reconnected to other sessions. Then the data will be increased by a Version and re-registered to the Session, and the Session will be sent to that Data again.
