Environment/Versions Spirent TestCenter PGA Answer Attached a sample for this use case. In the sample, the user create the 3 stream blocks and configure what ever attributes are desired per block (burst, frame size, content).  Set the TX port generator to Priority Based mode. CBR traffic is set to Priority 0, additional blocks are set with a value of 1-31. Port Based mode may see bursty traffic. Priority Based will be better at Constant Bit Rate. The lower the number, the more guarantee that the stream block pattern will be reproduced in the presence of congestion. Attachments Attachment VBR and CBR.tcc
