Abstract: The present invention discloses a detection method of security equipment based on ALG protocol to realize TCP stack information leak, including: S1, a client sending a detection packet containing an ALG protocol stack to a server; S2, the server responding to the detection packet, wherein a response packet of the server in response to the detection packet includes basic information of a software to be detected and protocol stack information of the security equipment; S3, the client receiving the response packet. The detection method constructs a detection packet containing a protocol stack of a security equipment to enable the security equipment to return the corresponding protocol stack information, thereby recognizing the transparent deployed security equipment to achieve a genuine purpose of network equipment recognition.

Abstract: The present disclosure provides systems, methods, and computer-readable media for managing graphics processing unit (GPU) allocation for a virtual machine (VM). A first GPU driver, associated with a first GPU, is offloaded from an operating system (OS) of the VM. Then, the first GPU is deallocated from the VM. A second GPU is allocated to the VM, and a second GPU driver, associated with the second GPU, is loaded in the OS of the VM. To restore a GPU context from the first GPU within the second GPU, a GPU command log from the first GPU is replayed to the second GPU.

Abstract: A method for implementing GPU virtualization. The method is applied to a physical host and the physical host includes: a hardware layer including a GPU, a Host running on the hardware layer, and N back-end GPU Domains and M front-end VMs that run on the Host, where there are service channels between the N back-end GPU Domains and the M front-end VMs. The method includes: transferring, by an mth front-end VM, a GPU command to an nth back-end GPU Domain based on the service channels; and processing, by the nth back-end GPU Domain, the GPU command by using a GPU, to obtain corresponding processing result data, where the type of the operating systems running on the nth back-end GPU Domain and the mth front-end VM is same. The invention helps to optimize performance of a GPU virtualization system.
