Dual bank traffic generator

摘要

There are disclosed traffic generators, methods, and computer readable media to generate packets for testing a network under test. A first parameter memory bank may be active when a first bank select data has a first value and inactive when the first bank select data has a second value. A second parameter memory bank may be inactive when the first bank select data has the first value and active when the first bank select data has the second value. One or more engines may generate packets based on parameters stored in the active one of the first and second parameter memory banks. A processor coupled to the first and second parameter memory banks may write parameter data into the inactive one of the first and second parameter memory banks.

1. A traffic generator to generate packets for testing a network under test, comprising:
a first parameter memory bank, the first parameter memory bank active when a first bank select data has a first value and inactive when the first bank select data has a second value; a second parameter memory bank, the second parameter memory bank inactive when the first bank select data has the first value and active when the first bank select data has the second value; one or more engines to generate packets based on parameters stored in the active one of the first and second parameter memory banks; and a processor coupled to the first and second parameter memory banks and configured to write updated parameter data into the inactive one of the first and second parameter memory banks, wherein the one or more engines store one or more state variables in a state memory, and at least some of the state variables are reset to respective predetermined values when the first bank select data changes between the first value and the second value.
