The present invention provides methods, systems, devices, and computer program instructions for enabling low-power wireless devices (such as wireless telephones and personal digital assistants, or PDAs) to connect to a fast wired or wireless voice/data network. A novel relay point device, referred to as an “extension point”, is defined that flexibly extends the effective reach of network access points. Use of extension points enables the network infrastructure to be expanded (and subsequently re-configured, if necessary) simply and cost-effectively, requiring little or no additional physical wiring. The defined techniques provide an infrastructure that is scalable, supporting a large number of end users without substantial degradation to connection establishment time and data rates. Using the disclosed techniques, end devices are able to reach network services, and to communicate with other end devices, beyond the nominal working range of these devices and without limitation to the numbers of such devices.

The present disclosure describes a method for monitoring the quality of service of H.264 multimedia communications. The present disclosure achieves the in-band QoS monitoring of the H.264 multimedia communications, thereby reducing extra overhead introduced by the QoS monitoring. The present disclosure makes direct use of the extension message mechanism of the high level media protocol H.264 per se to bear QoS report information without use of any extra channel, so as to achieve an “in-band” QoS report mechanism. The H.264 message extended mechanism, e.g., an SEI message, is used to self-define user data for transmission of the QoS report to monitor a transmission quality of the H.264 multimedia communications, without influence upon communications of any existing device in the H.264 protocol while reducing extra bandwidth overhead. Various protection measures are also provided based upon the use of the H.264 in-band report to improve the reliability of the RTCP/UDP.

A multi-lingual tag extension mechanism suitable for use with the JAVASERVER computer software Pages platform. Rather than creating a closure abstraction, the present invention “in-lines” a body evaluation for the tags. A doStart ( ) method processes a start tag and determines if a body needs to be evaluated. If so, a body evaluation buffer is passed to a doBody ( ) method for body evaluation. Once the body evaluation is complete, a doEnd ( ) method completes the processing by synchronizing the variables. The scripting details of the present invention match any nesting of the tag, so the at the structure corresponding to the original scripting is preserved. Furthermore, the present invention is not dependent on the specifics of the scripting language used to form the Web page.

A computer OS with an extended file attribute (EFA) is proposed to extend, without modifying a legacy virtual file system, the legacy file attribute of legacy files where each legacy file includes a file content and a legacy file attribute. The OS has a file attribute extension mechanism for adding EFA to the legacy file attribute. The file attribute extension mechanism includes: a) During EFA creation, adding EFA to legacy file attribute by concatenating an encoded file content extension to the file content. b) During EFA access, decoding the encoded file content extension and accessing the EFA. Also included is an Application Programming Interface (API) mechanism for generating system call to access each file. In turn, the system call firstly calls the legacy virtual file system to access each file plus legacy file attribute and concatenated encoded file content extension, and secondly accesses EFA via the file attribute extension mechanism.
