The system and method utilize an algorithm for transmitting the data packets with restoration of lost data during data transfer over UDP Protocol encrypted with DTLS Protocol. Advantageously, the algorithm does not require changes to data for either UDP or DTLS packets, but rather a separate, specifically designed packet is transmitted to the recipient to facilitate and ensure the recovery of any lost data packets over the unreliable network.

Abstract: Virtual computer systems (virtual machines) have become increasingly common with the evolution of virtualization technology, cloud computing, etc. However, as a virtual machine and its associated guest operating system seek to execute and/or access a page of memory through synchronous processes execution of the virtual processor associated with the virtual processing is blocked until the page of memory is locked and available. Accordingly, time is wasted on calls waiting for physical page availability thereby reducing utilization of the host machine and virtual machine respectively. To address this an asynchronous virtual machine environment is established allowing the virtual machine or physical machine to handle additional operations whilst waiting for physical page availability.

The described technique may be used when handling a request to launch a remote session using a specified virtual template. A virtual machine (VM) type associated with the virtual template and that indicates hypervisor compatibility of the virtual template may be determined. A destination hypervisor is selected for executing the remote session. If VM type is not compatible for execution on the destination hypervisor, a converted, native VM image file is generated which is compatible with the destination hypervisor. The remote session is then launched on the destination hypervisor using another VM executed using the converted VM image file.
