Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

Abstract: A system and method for maintaining provisioned configuration for an endpoint in a packet switched communications network are disclosed, the communications network utilizing a signalling protocol between the endpoint and at least one gatekeeper. The gatekeeper receives a request from the endpoint, determines the addresses of an assigned gatekeeper and at least one alternate gatekeeper, and transmits the addresses to the endpoint within the signalling protocol. The endpoint sends a message to its assigned gatekeeper, and if the assigned gatekeeper is responsive, the endpoint receives an indication confirming that the Gatekeeper is available. If the assigned gatekeeper is unresponsive, the endpoint registers with an alternate gatekeeper, but periodically sends a polling status request to its assigned gatekeeper, so that when the assigned gatekeeper becomes responsive, the endpoint may then register with its assigned gatekeeper.

Abstract: A system for client initiated authentication comprises a user agent client and a user agent server. The user agent client is operable to communicate a session initiation protocol request. The session initiation protocol request comprises an authenticate header and a require header that comprises a server authentication tag. The user agent server is operable to receive the session initiation protocol request. The user agent server is further operable to communicate a session initiation protocol response in response to the session initiation protocol request. The session initiation protocol response comprises an authorization header having a credential of the user agent server.

Abstract: Described herein is a method and system for multiplier optimization. A gate count savings that does not introduce additional quantization error can be achieved with this method and system. By increasing the number of digits in a multiplication result, partial products within a multiplication can be truncated. When the multiplication result is used in a subsequent operation, the gates required for the increased number of digits in the multiplication result can be made less than the gates saved within the multiply.

Abstract: A cluster of alternate gatekeepers handles the load of a single logical zone. The alternate gatekeepers exchange signals among each other according to a special cluster protocol. Each alternate gatekeeper may be connected and exchange signals with endpoint devices.

Abstract: An apparatus and method for determining inter-frame motion during compression of digital video data incorporates a computationally efficient hierarchical block-matching motion estimation technique in conjunction with a full-search block-matching approach. In the hierarchical block-matching method, a macroblock is filtered and decimated, and a search area is also filtered and decimated. A block-matching search is performed within the filtered and decimated search area. An augmented block in the original search area that corresponds to the block in the decimated search area that provided the best match with the decimated macroblock is then compared with the original macroblock to determine a motion vector. Operating parameters specify the search range based on the type of frame being processed, i.e. P-frame or B-frame, and, in the case of B-frames, the distance of the B-frame from the reference frame.

Abstract: A coding conditions selection apparatus, adapted for inclusion in an MPEG-II encoder chip, and methods for selecting encoding parameters for a macroblock of video data includes an encoder decision block ("EDB") for receiving and concurrently stratifying into a plurality of blocks digital video data associated with a macroblock. Each block may correspond to video data for pels of the macroblock, or a block may correspond to differences produced by subtracting digital video data for pels of a reference frame of video from digital video data for pels of the macroblock. The EDB while evaluating functions, e.g. either a variance or a mean square error, concurrently processes the stratified data for several blocks while avoiding any redundant computations. A plurality of encoding conditions are determined based upon the block function evaluations.

Abstract: A video image frame consisting of a two-dimensional array of picture elements (pixels) is decomposed into a set of rectangular image portions (tiles). Within each tile, variance between pixel intensity values is less than a predetermined value. A tile is encoded by a value set identifying the tile and including a single intensity value for all pixels in the tile. Frame-to-frame variation of the video image is encoded by inter-frame tile comparison and encoding of sub-tiles representative of change from a previous frame to a current frame.
