1. A system for data generation with low-overhead sequence number generation, the system comprising: a data storage entity for storing a set of coefficients for generating a sequence of numbers according to a desired pattern; a sequence number generator for generating the sequence of numbers according to the desired pattern for insertion into a data stream, wherein the sequence number generator reads from the data storage entity the set of coefficients and uses the set of coefficients to calculate a value for a sequence number according to an equation for calculating a sequence number value and wherein, during generation of the sequence numbers, the values of the set of coefficients that are stored in the data storage entity do not change; and a data generator for generating and sending a data stream that includes the generated sequence numbers over a network.
