Abstract
A method and system for communicating between operating systems using an interface that provides an abstraction layer of one of the operating systems. At least one channel is created that allows messages and data packets to be transferred between the operating systems without converting the data into an operating system's format before sending the data to another operating system. The interface provides commands for each of the operating systems to use to communicate with each other and provides the flexibility to create platform specific extensions to the provided commands. The interface also allows a first operating system to demand load devices on a second operating system by extending demand load functionality of the second operating system to the first operating system. A second channel is created that is used to only send data and data related control messages on the channel, eliminating the need to distinguish between general control messages and data specific control message.
