Embodiment Construction

[0037] A preferred embodiment of the invention is used in a residential gateway comprising a microprocessor system, eg running with a Unix-like operating system, including ROM and RAM memory. An operating system includes application programs and utilities that represent real files, and the main control program, the kernel. The method of the present invention proposes specialized virtual files designed to match the desired result, making these files available in the file system such that they do not pollute the file system namespace and do not interfere with the real files inside the file system. The content of the virtual file depends on the user's requirements, and as such, the content can be regarded as an agreement, for which a convention must be reached between the two parties.

[0038] The present invention therefore describes a generic method that can be used in file system implementations to avoid that applications using such file systems have to emulate missing functio...

Abstract

The method for operating a file system comprises the steps of designing a virtual file to provide a result from the file directory for which a multitude of system calls is required, distinguishing the virtual file by a unique name from the real files of the file directory, and retrieving the result from the file directory by opening the virtual file and reading the content of the virtual file. The virtual file is designed in particular for a file system operation.

Description

technical field [0001] The present invention relates to a method and device for operating a file system including a file directory, and in particular to a home gateway using the method. Background technique [0002] Home gateways, which connect an end user's home network to the Internet, are widely used in intervals. Home gateways typically provide broadband services via Digital Subscriber Line (DSL) and telephone communications known as POTS (Plain Old Telephone Service), and additionally include wired transport (e.g. Internet) and wireless transport (Wi-Fi) for home networks . To provide services, a residential gateway includes a microprocessor system (CPU) running on a Unix-like operating system. [0003] An operating system includes applications and utilities along with a main control program (kernel). The kernel provides services to start and stop programs, handle file systems and other common "low-level" tasks shared by most applications, and schedule access to avoi...
