Abstract
A packet comparator includes a match packet buffer and a first in first out (FIFO) buffer that stores a reference packet stream. Once a packet in the reference stream and a candidate stream are matched to the match packet, the reference stream and the candidate stream are considered synchronized. Thereafter, the two streams are passed through a compare function and a resultant stream is output from the packet comparator. Possible resultant streams include the results of an exclusive OR (XOR) operation between all, or selected parts, of packets in each of the streams.
