Abstract: Systems and methods are provided for resolving domain name services (DNS) queries for address information about hosts on a network. The queries are posited from remote users across a satellite or other remote link to a network, and are monitored as they pass through a central node logically present between the remote link and the network. A list of statistically significant hosts on the network is maintained and transmitted from the central node to the plurality of remote users across the remote link. By providing the remote nodes with a current list of popular hosts and associated address information, subsequent domain name services queries placed for the statistically significant hosts may be resolved without communicating across the remote link.

Abstract: Systems and methods are provided for resolving domain name services (DNS) queries for address information about hosts on a network. The queries are posited from remote users across a satellite or other remote link to a network. In response to a domain name services request from the client containing a name of the server, a placeholder address is generated and provided in response to the client. After a subsequent request for a connection to the server is received, the name of the server is re-associated with the placeholder address and the connection request containing the proper host name is forwarded across the data link. A hub processor receives the request for connection, resolves the name of the server to an address on the network, and establishes a connection between the client and the server using the address on the network.

Abstract: A method and system for detecting matching strings in a string of characters utilizing content addressable memory using primary and secondary matches is disclosed.

Abstract: The current invention involves a forward error detection system, especially for use with Low Density Parity Check codes. A parallel SISO structure allows the decoder to process multiple parity equations at the same time. There is a new SISO decoder which allows for the updating of the Log-likelihood-ratio's in a single operation, as opposed to the two pass traditionally associated with the Tanner Graph's. In the decoder, there is a mapping structure that correctly aligns the stored estimates, the stored differences and the SISO's. There is also the ability to deal with multiple instances of the same data being processed at the same time. This structure manages the updates and the differences in such a manner that all calculations on a single piece of data that are processed in parallel are incorporated correctly in the new updated estimates.

Abstract: A method and apparatus for decoding a linear block encoded string of information bits comprising: converting the string into a plurality of codewords. Performing hard and soft decisions on each codeword to generate a hard and soft decision vector. Computing the syndrome and finding the location of the two minimum values by Galois Field Arithmetic. Designating these values LOW1 and LOW2 and xoring with a Nc1, thus generating Nc2. Swapping Nc1 with Nc2 and determining the lowest soft decision value, Min1 and a next lowest value, Min2. The two bit locations creating Min1 are designated as MinA and MinB. MinA being replaced with Min2 minus the value MinA. MinB being replaced with Min2 minus the value at MinB. Generating an output codeword by subtracting Min1 from all other bit locations values and 2's complementing all soft values with 0 in their location. Creating the new soft value vector.

Abstract: The invention provides systems and methods for continuous back up of data stored on a computer network. To this end the systems of the invention include a synchronization process that replicates selected source data files data stored on the network and to create a corresponding set of replicated data files, called the target data files, that are stored on a back up server. This synchronization process builds a baseline data structure of target data files. In parallel to this synchronization process, the system includes a dynamic replication process that includes a plurality of agents, each of which monitors a portion of the source data files to detect and capture, at the byte-level, changes to the source data files.
