The present invention is a system and method for distributed, highly scalable, wide area peer-to-peer network data storage. The functionally equivalent servers in the system are divided into groups. Each server maintains a dynamic list which is polled to determine the availability of the closest neighbor servers. Each server is switched between the groups of servers to optimize network connectivity parameters. Data and directory files are divided into a plurality of pieces which are stored on different servers. Files are uniformly and independently named, utilizing a tree with a common root, logical pathways, and unique file identifiers. When a server receives a client request for file system access, the plurality of file pieces are collected and sent to the client server from the neighbor servers simultaneously in order to optimize bandwidth. Servers with maximum throughput capacity are utilized for highest transmission speed and reduced processing time.

An integrated search engine includes a hierarchical memory configured to support a plurality of multi-way trees of search keys. These multi-way trees, which share a common root node, support respective databases of search keys. The child pointers associated with search keys within the common root node may be allocated at a single key level of granularity, which means that each search key within the common root node may be associated with a pair of child pointers when each search key within the common root node is associated with a different multi-way tree of search keys.

System, method and program product for transcribing an audio file included in or referenced by a web page. A language of text in the web page is determined. Then, voice recognition software of the language of text is selected and used to transcribe the audio file. If the language of the text is not the language of the audio file, then a related language is determined. Then, voice recognition software of the related language is selected and used to transcribe the audio file. The related language can be related geographically, by common root, as another dialect of the same language, or as another language commonly spoken in the same country as the language of the text. Another system, method and program product is disclosed for transcribing an audio file included in or referenced by a web page. A domain extension or full domain of the web page and an official language of the domain extension or full domain are determined. Then, voice recognition software of the official language is used to attempt to transcribe the audio file. If the official language is not a language of the audio file, then a language related to the official language is determined. Then, voice recognition software of the related language is selected and used to transcribe said audio file. The related language can be related geographically, by common root, as another dialect of the same language, or as another language commonly spoken in the same country as the official language.

A seal assembly including first and second rigid shields and a sealing member carried by the first shield and having a first and second annular sealing lip in sealing engagement with respective sliding surfaces of the second shield. The first sealing lip carries in a radial seat thereof a toroidal spring exerting a radially eccentric thrust on the first sealing lip with respect to an elastic hinge defined by a common root portion of the lips, having a center of rotation located along a line extending through a V-shaped sealing edge of the first lip and forming a 20° to 60° angle with a radial plane. The root portion is defined between two opposite annular recesses having a U-shaped cross-section and bottom walls facing each other, substantially aligned along the aforementioned line.

A multiple spanning tree protocol (MSTP) network topology convergence method is disclosed in the embodiment of the invention. The method comprises: a network device acquires through a target port a Bridge Protocol Data Unit (BPDU) message carrying spanning tree protocol (STP) information and updates the STP information of the target port; the network device compares the common root information contained in the STP information of other reception ports with the common root information contained in the acquired STP information, and compares region root information contained in the STP information of the other reception ports with the region root information contained in the acquired STP information; and the network device updates the external path overhead of those reception ports of the other reception ports found through comparison to be consistent into the overhead indicated by the external path overhead information contained in the acquired STP information. Correspondingly, a network device and a system are also disclosed in the embodiments of the invention. With the embodiments of the invention, invalid BPDU messages can be avoided in an MSTP multi-region networking environment with complicated networks, and thus rapid convergence can be implemented among the network devices.

The present invention relates to a communication system comprising a first node and second node adapted for communicating in a network, wherein the first node comprises a first list of keying materials including a plurality of keying materials, wherein the second node comprises a second list of keying materials including a plurality of keying materials, wherein the first node further comprises a receiver for receiving from the second node a second node identifier, a controller being arranged for determining from the second node identifier the position in the first list of at least one keying material having a common root with one keying material of the second list, and for generating an encryption key by means of the keying material having a common root and the second node identifier.
