Background Along with gradual evolution of an operating system to multiple terminals, across scenes and distributed directions, the expansion capability of peripheral equipment becomes an important foundation of whether the system can construct complete ecology. Peripheral extensions not only mean compatibility with legacy USB, bluetooth, etc. interfaces, but also involve adaptation to different bus protocols, different modes of deployment, and different application layer requirements. Particularly in a distributed environment, the peripheral of a single device is not limited to local call, but needs to be oriented to networking and cross-node shared access, which puts higher requirements on a peripheral extension method. Therefore, how to implement unified peripheral abstraction, stable driving loading and flexible calling mechanism has become a key topic in system architecture design. In the prior art, the access and the call of the peripheral are mostly realized under a single protocol and a single scene, and the capability of cross-protocol identification and stability quantitative analysis is lacking, so that identification delay and access failure are easy to occur in a complex application scene. Meanwhile, the traditional drive loading mechanism often emphasizes the usability of functions, but ignores the dynamic balance of loading efficiency and system resource occupation, so that partial drive calling times are insufficient to occupy resources for a long time, or system blocking occurs in a high concurrency scene. In addition, in the aspect of safety control and call delay management, most of the existing methods are in fracturing treatment, and the integrity and traceability requirements on external call in a distributed environment are difficult to support. These drawbacks make it difficult for peripheral extension methods to meet the high performance, high security requirements of current operating systems.
