	At the DESY site in Hamburg/Germany the linear accelerators FLASH and European XFEL are successful operated by the control system DOOCS. DOOCS based on the client’server model and communicates with the matured SUN-RPC. The servers are build with a framework which consists of several C++ libraries.

At the DESY site in Hamburg/Germany the linear accelerators FLASH and European XFEL are successful operated by the control system DOOCS. DOOCS based on the client’server model and communicates with the matured SUN-RPC. The servers are build with a framework which consists of several C++ libraries. The clients use a DOOCS client library implementation in C++ or Java. In the past years the public interface (API) of the C++ client library was refined. But modern C++ features like futures are not provided in the API. Massive multi-processing, parallel communication, and optimized names resolution could improve the overall communication latency. The usage of the standard C++ library, the limit of external dependencies to SUN-RPC and OpenLDAP, and the reduction of the code size, may increase the maintainability of the code. This contribution presents an experimental new client C++ library which achieves these goals.
