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, wherein the sequence number generator calculates the value for the sequence number according to the equation, which uses the values for the set of coefficients and a dependent variable and wherein the dependent variable is provided by a counter comprising at least one of a loop counter, a count-up counter, and a count-down counter; and a data generator for generating and sending a data stream that includes the generated sequence numbers over a network.
