Abstract
The reliability of a high-speed digital data traffic channel is determined by establishing end-to-end synchronization by use of confirming error detecting data transmitted on a side channel from an originating end, comparing the traffic data and the error detecting data and from time to time re-confirming the validity of the synchronization.
Claims20
A method for determining end to end reliability performance of high speed digital data channels having two originating ends comprising:
- (a) establishing for at least one direction end to end synchronization by use of data transmitted by a side channel
- (b) confirming the validity of the synchronization
- (c) calculating and transmitting over the side claimed data including CRC data from an originating end
- (d) performing a comparison of the data and CRC data
- (e) from time to time reconfirming the validity of the synchronization.
A method for determining reliablity performance of a high speed data chennel adapted to transmit data between at least two ends comprising a transmitting end and a receiving end, said method comprising:
- (a) establishing, by use of data transmitted over a side channel between said two ends, the time synchronization of data transmitted from said transmitting end and data received at said receiving end
- (b) confirming the validity of the synchronization
- (c) calculating and transmitting over a side channel data representative of a portion of the data in the high speed channel
- (d) performing a comparison of said portion of the data in the high speed channel and said data transmitted over said side channel
- (e) from time to time reconfirming the validity of the synchronization.
