A method searches and tests for performance optima in an operating system (OS) configuration space. The method includes generating a plurality of OS configurations. For at least a first OS configuration, of the generated OS configurations, the method further includes: fetching a plurality of OS modules based on the first OS configuration; building a first OS image from the fetched OS modules; and testing the first OS image to determine a first value of a performance metric.

Fast operating system configuration option space exploration via cross-OS grafting

A method for establishing a TCP connection between a first end-point and a second end-point includes: establishing a first TCP connection between the first end-point and the second end-point; the second end-point dynamically deciding on redirecting the first TCP connection via a chain of proxies that interconnects the first end-point and the second end-point; based upon a case of a redirection decision by the second end-point occurring, the first end-point establishing a new TCP connection with the first proxy of the chain of proxies; and establishing a segmented TCP connection between the first end-point and the second end-point via the chain of proxies and transferring data between the first end-point and the second end-point through the chain of proxies.

Method and server for establishing a TCP connection

Methods and systems for building an optimized image for an application are provided. An operating system is decomposed into granular modules. An initial configuration file to a build system is provided. The build system builds an initial image including initial modules for the application based on the initial configuration file. A monitoring system monitors performance indicators for the initial image. Using a machine learning algorithm, a subsequent configuration file based on the performance indicators is derived. The build system, builds a subsequent image for the application.

Method and system for automated building of specialized operating systems and virtual machine images based on reinforcement learning

A method for operating virtual machines on a virtualization platform includes: embedding control information in a predetermined memory area of a front-end virtual machine where at least one virtual device is to be initialized, the control information being required for initiating a communication with a back-end virtual machine where at least one back-end driver runs; retrieving, by the front-end virtual machine, the control information from the predetermined memory area of the front-end virtual machine; and performing the communication between the front-end virtual machine and the back-end virtual machine via a direct communication channel to exchange information for initializing the at least one virtual device of the front-end virtual machine, by communicating with the at least one back-end driver via the direct communication channel. The direct communication channel is established based on the control information embedded in the predetermined memory area of the front-end virtual machine.
