20100017410 | TECHNIQUES FOR EXTENDING AND CONTROLLING ACCESS TO A COMMON INFORMATION MODEL (CIM) - Systems and methods for extending and controlling access to a Common Information Model (CIM) are presented. According to an embodiment, access requests for a CIM object manager (CIMOM) pass through a CIM file system (CIMFS) where each access requested is authenticated. The CIMFS maintains and manages a hidden file system representing CIM classes and a CIM class hierarchy on a volume of storage. The structure, metadata, and values for the CIM classes, CIM object, and CIM providers are maintained in a hidden directory on the volume. This information is accessible via the CIMFS to use existing file system management operations. | 01-21-2010 |
20100017422 | FILE SYSTEM INTERFACE FOR CIM - Systems and methods for managing systems using common information models (CIM) are presented. According to a method embodiment, CIM functions are provided, and a file system interface for the CIM functions is provided. An embodiment of a method receives file operation commands through a client interface and performs CIM functions corresponding to the received file operation commands based on a mapping of the file operation commands to the CIM functions. | 01-21-2010 |

20100272124 | METHOD AND SYSTEM FOR REDUCTION OF DECODING COMPLEXITY IN A COMMUNICATION SYSTEM - Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity. | 10-28-2010 |
20110317565 | METHOD AND APPARATUS FOR TESTING TRAFFIC AND AUXILIARY CHANNELS IN A WIRELESS DATA COMMUNICATION SYSTEM - Techniques to test performance of terminals and access points in CDMA data (e.g., cdma2000) systems. A framework of protocols and messages is provided to support systematic performance testing of terminals and to ensure interface compatibility. The framework comprises a Forward Test Application Protocol (FTAP) for testing forward channels and a Reverse Test Application Protocol (RTAP) for testing reverse channels. Techniques are also provided to (1) test different types of channels (e.g., traffic channels as well as auxiliary channels), (2) test bursty data transmissions, (3) support “persistence” testing (i.e., continued testing over connection and disconnection), (4) force the settings of certain auxiliary channels (e.g., so that the error rate of the channels may be determined), and (5) collect, log, and report various statistics that may be used to derive performance metrics such as throughput and packet error rate. | 12-29-2011 |
