摘要： Echo messaging for operation, administration, and management of a service-based distribution path and associated services are disclosed. Service-based distribution paths or transport tunnels include services mapped or bound to a path associated with the transport tunnel. Echo messaging provides OAM capabilities to monitor the operational state of a service-based distribution path, including determining configuration, connectivity, and other characteristics of the path and associated services that transport data. OAM functions provided by echo messaging enable OAM functions despite service volume along a core network, path or set of paths.

摘要： In one embodiment, the present invention is directed to a method for inserting errors into data to facilitate validation of an error detection algorithm. The method comprises: receiving a data corruption command for a plurality of bits; determining, from the data corruption command, a plurality of bit fields within the plurality of bits for data corruption; determining a minimum and maximum number of errors for each of the plurality of bit fields; determining a total number of errors to be inserted; inserting the minimum number of errors into each of the plurality of bit fields at random locations; and randomly inserting additional errors into the plurality of bit fields subject to the maximum number of errors until the total number of errors are inserted.

摘要： Integrated circuit devices include data inversion circuits therein that are configured to evaluate at least first and second ordered groups of input data in parallel with an ordered group of output data previously generated by the data inversion circuit. The data inversion circuit is further configured to generate inverted versions of the first and second ordered groups of input data as versions of the first and second ordered groups of data in parallel at outputs thereof whenever a number of bit differences between the first ordered group of input data and the ordered group of output data is greater than one-half a size of the first ordered group of input data and a number of bit differences between the second ordered group of input data and the version of the first ordered group of input data is greater than one-half a size of the second ordered group of input data, respectively.

摘要： An apparatus and process for measuring, testing, and/or characterizing high-speed bit streams includes repeating a serial bit steam and repetitively undersampling the repeated bit stream at a plurality of timing locations. Samples for each timing location are separately accumulated, and accumulated values are examined to determine the probability of the bit stream being high or low at each timing location. Identification of a periodic bit stream as well as measurement of jitter and other timing characteristics can then be measured.
