REQUEST PROCESSING TECHNIQUES

摘要

A computer system implements a hypervisor which, in turn, implements one or more computer system instances and a controller. The controller and a computer system instance share a memory. A request is processed using facilities of both the computer system instance and the controller. As part of request processing, information is passed between the computer system instance and the controller via the shared memory.

主权项

1. A computer-implemented method for processing a request, comprising:
under the control of one or more computer systems configured with executable instructions,
providing, using a virtualization layer, a virtual computer system instance and a controller such that:
the controller includes a layer of a protocol stack lacked by the virtual computer system instance; anda shared memory region is accessible to both the virtual computer system instance and the controller;transferring request data from the controller to the virtual computer system instance using the shared memory region;transferring data responsive to the request from the virtual computer system to the controller using the shared memory region; andusing the controller's layer of the protocol stack to provide a response to the request, the response based at least in part on the data responsive to the request.
