International Classification:

H04J 1500

US Classification:

370254, 370256

Abstract:

A bridged network and a method for performing bridged network topology acquisition. The bridged network includes network segments and smart bridges having one or more ports. The network segments are interconnected by the smart bridges via the ports. Each of the smart bridges being configured to perform steps to accomplish the network topology acquisition. The method also performs steps to accomplish the network topology acquisition. The steps include an inventory construction that compiles a list of the ports that are connected to each of the network segments. Among the ports that are connected to any of the network segments the inventory construction respecting each port operates cooperatively so as to cause the list respecting each of the ports to converge rapidly to the state in which all the lists are similar and yielding a uniform segment inventory. The bridged network topology acquisition in each of the smart bridges operates cooperatively with the bridged network topology acquisition in other smart bridges in order to create a total network report from most recent segment inventories. The bridged network topology acquisition includes propagation, collection, and distribution.

US Classification:

Abstract:

Managing end stations locations in a bridged network includes providing a smart bridge, and performing communications operations using a network flood active port connections table, a network flood reaching table, a best path forwarding table and a best path sourcing table. An end station locations revision manages a host location (HLOC) table. End stations locations revision is invoked upon detection of changes in any end station location. The end stations locations revision exchanges location revision grandparent (LRG), a location revision child (LRC) table and a location revision wavefront distribution protocol. The locations revision passes the location revision request from the smart bridge over a topology of the bridged network. A location revision wavefront starts at the root and, spreads a location revision request for revising the HLOC of the other smart bridges. The wavefront spreads by wavefront protocol.

US Classification:

707102, 707100, 707101, 7071041

Abstract:

A client-side application (such as a browser, a browser plug-in, a browser toolbar plug-in, etc. on an end user's computer) is used to support the serving of content-relevant ads to the client device. The client-side application may provide such support by sending document information (such as a document identifier, document content, content relevance information, etc. ) to a content ad server. The client-side application may also be used to combine content of the document and the content-relevant ads. For example, the client-side application may combine content of the document and the ads in a window (e. g. , in a browser window), may provide the ads in a window above, below, adjacent to a document window, may provide the ads in “chrome” of the browser, etc.

International Classification:

US Classification:

713176, 705 75, 283 13, 383176, 383308

Abstract:

Methods and systems are disclosed for providing secure transmissions across a network comprising a transmitting device and a receiving device. At the transmitting device, a stream of watermark bits is generated. Next, a plurality of watermarks is generated, each of the plurality of watermarks comprising an index number and a portion of the stream of watermark bits. The watermarks are inserted into each header of a plurality of outgoing packets. At the receiving device, the plurality of outgoing packets are received and it is determined if a received packet is valid based on the watermark in the header of the received packet. The stream of watermark bits may be generated using a stream cipher such as RC4, a block cipher such as 3DES in CBC mode, or other equivalent pseudo-random stream generating techniques.
