摘要:
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.

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.

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.

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. Each agent may record the changes to a respective journal file, and as the dynamic replication process detects that the journal files contain data, the journal files are transferred or copied to the back up server so that the captured changes can be written to the appropriate ones of the target data files.
