(For a long time, remote sites connected through low-speed links have used dedicated server hardware for optimal performance. However, due to cost pressure, lack of skills and the need to better deal with safety issues. Integrating server functions into the main data center is the main method to realize server integration. Unfortunately, since the widely used client protocols (such as CIFS for Microsoft file sharing and outlook mail transmission) were originally designed for LAN, it takes a lot of request response cycles to complete the task. The long response time has a serious impact on the user experience, even in the case of low link utilization.)
