Abstract: A system, method and computer program product for controlling virtual private servers includes a plurality of virtual private servers running on a host computer. An address and a unique identifier can be associated with each virtual private server. A control procedure(s) is within each corresponding virtual private server, and can be used to control that virtual private server in response to control commands. A control interface is outside the virtual private servers and can be used for control of the virtual private servers in response to control commands. The virtual private server can be a Virtual Private Server. The control command can be executable by both the control procedure(s) and the control interface, or can be executable by the control interface if the control procedure(s) is unreachable, or can be executable by the control interface if the virtual private server has failed, or can be executable even if the virtual private server is inaccessible.

Abstract: A system for maximizing the efficiency of a load balancing server for an asymmetric web farm utilizes a TCP stack and data packets to send and receive client service requests. An internal buffer enables each web server in the web farm to balance their loading based on the contents of the client service request. Data switching between the address portion of the user space and the address portion of the kernel space within the load balancing server is eliminated.
