719 results about "Interoperation" patented technology

In engineering, interoperation is the setup of ad hoc components and methods to make two or more systems work together as a combined system with some partial functionality during a certain time, possibly requiring human supervision to perform necessary adjustments and corrections.

Enforcing uniform file-locking for diverse file-locking protocols

The invention provides a method and system for correct interoperation of multiple diverse file server or file locking protocols, using a uniform multi-protocol lock management system. A file server determines, before allowing any client device to access data or to obtain a lock, whether that would be inconsistent with existing locks, regardless of originating client device or originating protocol for those existing locks. A first protocol enforces mandatory file-open and file-locking together with an opportunistic file-locking technique, while a second protocol lacks file-open semantics and provides only for advisory byte-range and file locking. Enforcing file-locking protects file data against corruption by NFS client devices. A CIFS client device, upon opening a file, can obtain an "oplock" (an opportunistic lock). When a client device issues a non-CIFS protocol request for the oplocked file, the file server sends an oplock-break message to the CIFS client device, giving the CIFS client device the opportunity to flush any cached write operations and possibly close the file. Allowing NFS and NLM requests to break oplocks ensures that file data remains available to NFS client devices simultaneously with protecting integrity of that file data. A CIFS client device can obtain a "change-monitoring" lock for a directory in the file system, so as to be notified by the file server whenever there is a change to that directory. The file server notes changes to the directory by both CIFS and non-CIFS client devices, and notifies those CIFS client devices with "change-monitoring" locks of those changes.

Method and apparatus providing interoperation of execution images of different versions

A method is disclosed for providing interoperation of a first execution image of a first version and a second execution image of a second version. A compatibility matrix specifies whether the versions are compatible, base-level compatible, or incompatible. In one embodiment, the compatibility matrix may comprise a sparse table that stores a compatibility indicator for all permutations of a plurality of versions of a network operating system. As part of initialization of a system that includes the first execution image and second execution image, version information for the execution images is determined. An entry in the compatibility matrix corresponding to the versions is identified. The execution images are operated in a fully synchronized state when the identified entry of the compatibility matrix specifies that the versions are either compatible or base-level compatible. Individual components of the execution images interoperate according to the results of individual session negotiations. If the versions are incompatible, an alternative redundancy operation mode may be used. Embodiments provide for negotiation of compatible message versions and capabilities among peer components or clients of the execution images as source information to generate the compatibility matrix.

Intelligent scenic spot tourist safety service system based on GIS interoperation and LBS

The invention discloses an intelligent scenic spot tourist safety service system based on GIS interoperation and LBS. The system comprises a client, a server and a service monitoring center. Based on an automatic and intelligent interoperation protocol and a standard between a GIS server and a LBS mobile terminal, aiming at tourists, the system realizes position association, automatic position state perception, active early warning and concurrent linkage of multiple monitoring means. A safe think tank makes a decision so as to realize bidirectional high-efficiency position safety information interaction of the tourists and a scenic spot and a timely and rapid rescue service. The system is combined with A-GPS or Big Dipper, a base station and a WiFi positioning mode to acquire accurate position information of the tourists and working personnel in the scenic spot. On an aspect of a GIS interoperation server, an intelligent and automatic GIS space analysis algorithm is designed. A mobile terminal uses an APP to acquire a function support of the server. Precision and efficiency of safe monitoring and early warning of the scenic spot are increased; forecasting and early warning are performed; accident rescue work of the personnel in each scenic spot is scientifically guided and tourist safety is guaranteed.
