Abstract: In embodiments of the present disclosure, there is provided a solution for establishing queues between threads in a user space. After creating a first thread on a first application and creating a second thread and a third thread on a second application, a socket connection between the first application and the second application is established in the user space of the operating system. Then, a first queue is established between the first thread and the second thread, while a second different queue is established between the first thread and the third thread. Embodiments of the present disclosure can avoid lock-based queue sharing by setting a separate queue for each pair of threads. Thus, the luckless queue mechanism according to embodiments of the present disclosure can improve the performance of the operating system significantly.

Abstract: A technique provides a solution for establishing a socket connection in a user space. After receiving a request for establishing a socket connection from a first application, the monitor sends the connection request to a second application, wherein the first application and the second application run on the same computing device. Then, the monitor coordinates establishing, in user space of the operating system, a peer-to-peer socket connection between the first application and the second application. By establishing a socket connection in the user space of the operating system, embodiments of the present disclosure can achieve a user space socket connection between different applications within a single computing device, thereby improving the performance of the operating system. In addition, embodiments of the present disclosure use the monitor (or controller) to coordinate inter-application connection establishment and resource allocation, thereby ensuring security of the operating system.
